I had mentioned to someone that I hated how my executive dysfunction was stopping me from learning and practicing ROS 2, and they said that if it's giving me difficulty, maybe I should just do single scripts for now until I build up.

I'm very confused by what exactly that means. I'm still completely new to the world of robotics.

I'm in the process of developing a prosthetic leg for a small bird (around 1.5 cm long and 5 mm in diameter), part of the mechanism is fully mechanic and the "knee" part is electronic. The problem is that I'm having trouble finding the right actuator.

The samllest motor I've found is from the Petter Muren 1 gram ornithopter (1g Ornithopter Designed by Petter Muren - RC Groups), but haven´t been able to even find the name of that motor.

Ideally I'd love a pre made servo, but have considered making it myself.

Any ideas?

Hi, I'm an EE bachelor in my third year and i want to start making some projects to get more into robotics, computer vision and ML.

I'm quite proficient with c and cpp and I've done some 2D game development on FPGA with systemverilog, i have very solid foundations in math, physics, practical knowledge in analog circuits and a lot of theoretical knowledge in digital circuits.

I want to know what kind of tools or online courses one might suggest for me as all i've seen online is for complete beginners..

When I need something at the moment I usually order from Amazon as it’s easy and comes the next day, but it’s probably far from cost effective. I’ve never bought anything from AliExpress, but see it mentioned here and there. Is it cheap? Trustworthy? Does it takes ages to ship? What are people’s experiences? Are there better alternatives?

I’m working on a personal project right now for a self-balancing one wheel bot. My question is I want to know if it’s possible to lock two positions on a 3D plane, so that the bot can stay upright and not need to move in order to remain still. Picturing a pitch roll and yall gimbal, how would you lock two positions? Being that the robot will move forward and back when needed, the idea is to have the robot remain balanced at all times. Any ideas? would two separate gimbal be needed? Multiple gimbals?

Hi im indeed need your help very much , I'm still having a hardtime letting the robot go to from 1 position to 2nd position. And it seems that I can't send the pictures here but I feel like this is the details that you would like to know . I simulate this in coppeliasm using my own simple 3 DOF SCARA robot . Just a beginner level type of robot

Hi all, I'm working on building a 2-wheeled bot that uses n20 encoder motors to drive it forward. I'm using an Adafruit DRV8833 motor driver.

The motors are mounted on opposite sides of the bot, and need to turn in opposite direction to give the bot forward motion (ie. the left motor clockwise and the right motor counter-clockwise).

I have a question about the wiring and code options I can use to acheive this - and want to know if there is an option that is recommended.

Option 1:

Wiring:

Option 1 Wiring

Code:

void forward() {
  // Drives left motor 
  digitalWrite(AIN1, LOW);
  digitalWrite(AIN2, HIGH);


  // Drive right motor
  digitalWrite(BIN1, HIGH);
  digitalWrite(BIN2, LOW);
}

Option 2:

Wiring:

Option 2 Wiring

Code:

void forward() {
  // Drives left motor
  digitalWrite(AIN1, LOW);
  digitalWrite(AIN2, HIGH);

  // Drive right motor
  digitalWrite(BIN1, LOW);
  digitalWrite(BIN2, HIGH);
}

Both of these options work for my bot, and drive the motors in the appropriate directions.

I'm wondering if there is a recommended or most used option out of these two.

Hi all,

I just started my first job this week and it's my literal dream role - Senior Robotic Controls Engineer. However, I feel like I somehow "cheated" my way into this role and I wanted to know what everyone's first experience in industry was like. Apologies in advance for the long post!

Some background - I just graduated with an MS in MechE (concentration in robotics/controls). I'm the youngest on the team by 10+ years, everyone else is Staff/Principal. I've interned at the company before, but doing totally different work on a totally different team. The company works on multi-DOF robotic arms.

I took a robot dynamics course at the beginning of my Master's which went into arm dynamics (FK/IK, etc,). But my work since then has been modern/robust/classical/optimal control in various devices and mobile robots. In my interviews, it was clear my experience was not arm control - I answered questions about what I was currently working on and low-level controls very well, but stumbled on arm specific topics. I said I would need to brush up on them for sure.

I was pleasantly surprised to be hired. But in these past few days, I've been embarrassed about not being able to answer some basic questions about arm control from my mentor. I kicked myself when I found them in my dynamics class notes. I reviewed right after I stumbled in my interviews, but clearly not enough considering how long ago that class was. I've been checking in with my mentor as I review, and let him know it just took me a bit to make the switch back to arm control after spending the past year in mobile robots.

I am a very hard worker and am confident I can catch-up, but I'm starting to wonder what exactly I can contribute to the team. Everyone else has years of experience - my hiring feels like they took a chance. Did anyone else feel this unsure starting their first role in robotics? What were your experiences like your first few days and weeks? Any advice? Thank you all!

TLDR: I'm working on arm control in my very first job, and I've forgotten a lot! What am I doing here?

Hey everyone. I am a soon-to-graduate Mechanical Engineering PhD student from a top tier university who collected a Robotics masters along the way. I am hoping to transition into industry after graduation, and I'm really interested in Gecko Robotics because I am super interested in machines that climb (my thesis is about rodent tail usage during climbing)! I was wondering if anyone with experience at Gecko Robotics has any insight for me on:

1. What the workplace culture is like?
2. What the interview process was like?

Thanks in advance. Super excited to see what people say. Thanks.

hi ,

i have been thinking from a long time about making a robot and i started searching about it and ive got the idea of a simple chat robot .

a robot that can understand ( slang language) and reply like a normal person .

and for movement i have zero knowledge sooo any help would be aappreciable

im thinking about an rasspi 4 with a language model or any api or something like that .

it might be hard or even impossible but is there anyway to do this ?

thanks for reading : )

How can someone who is not very smart and has zero experience get started in robotics? Please read the rest before answering. I'm not looking for advice from PhD holders suggesting I return to college, as traditional colleges often cater to highly advanced students in engineering. I'm specifically interested in finding an affordable online bootcamp or training school that allows me to get training in this field while working a full-time job.

What advice would you give to someone interested in pursuing a career in robotics? What’s the best path to break into the field?

Hello everyone! I'm curious if entry-level roles in robotics are feasible for someone without an engineering degree (robot operator roles, entry-level field engineer roles, for example). I have 4 years of experience in tech, primarily in software and support, and I’m looking to transition into robotics. From my initial understanding, I’m particularly interested in the hardware side of robotics.

If entry-level roles aren’t feasible without an engineering background, I’m also open to returning to university, but I would love some guidance on what that path might look like.

Any guidance on how to make this shift effectively would be greatly appreciated!

I wanted to learn/use the Nvidia Isaac Toolkit, but in the documentation, its mentioned that I only runs on Ampere or higher NVIDIA GPU Architecture. I have a gtx 1660 laptop GPU. Can anyone suggest any workaround or other cloud-hosted tools that I can learn/use on ...

I'm trying to create a fighting robot that's 6 inches tall. I want it to be able to move and fight like the boxing robots "Noisy Boy", "Atom" and "Midas" from the movie Real Steel but at a 6 inch scale. I want the motions to be smooth and realistic. I didn't know where to start so I asked ChatGPT for help. Is it possible to make something like this if you followed the instructions? I know nothing about robotics or coding but want this vision to come to life. If you could build it for me or help me build it that would be great thank you!

1. Concept

1. Mechanics:
   • Up to ~12–15 Degrees of Freedom (DoF) for realistic human-like movement:
     • Arms: Shoulder (2–3 DoF), elbow (1–2 DoF), wrist (1 DoF).
     • Legs: Hip (2–3 DoF), knee (1–2 DoF), ankle (1–2 DoF).
     • Torso: Waist rotation (1 DoF), maybe an upper torso bend (1 DoF).
     • Head/Neck: Optional 1–2 DoF for expression.
2. Compact Actuation:
   • Rather than basic plastic-geared servos, consider advanced smart servos or even custom direct-drive mini actuators.
3. Onboard/Offboard AI:
   • For truly “intelligent” fighting, a local microcomputer or an offboard machine-learning pipeline that commands the robot in real time.
4. Realistic Fighting Styles & Motion:
   • Keyframe-based animation plus inverse kinematics (IK) for fluid transitions.
   • Advanced AI for move selection, combos, reactive blocks.
5. Multi-Sensor Feedback:
   • IMU (accelerometer, gyroscope) for balance/detecting hits.
   • Possibly a micro-camera or time-of-flight (ToF) sensor for environment perception.

2. Parts & Materials

Actuators (Servos or Custom Mini Actuators):

1. Robotis Dynamixel XL-320 or XL-330 Series:
   • Key Features: High precision, feedback on position, speed, load, temperature. Daisy-chain wiring.
   • Pros: Great for advanced control and “smooth” motion. Feedback loops help for dynamic movements.
   • Cons: Possibly larger than typical micro servos, but still relatively small.
   • Cost per unit: $40–$80 each
2. LewanSoul (Lobot) LX-16A Smart Servos:
   • Key Features: Serial bus interface, position/voltage/current feedback, metal gear.
   • Cost per unit: $20–$40 each
3. Custom Brushless Direct-Drive Mini Actuators
   • Note: Typically, these are found in high-end robotics labs. They’re incredibly small, expensive, and often custom-fabricated. If you want “ultimate performance,” you could explore collaborating with a specialized manufacturer or using micro brushless motors with tiny planetary gearboxes.
   • Cost: Can be $100+ per joint.

Number of Actuators Needed: ~12–15 total for full realism.

Electronics & Control:

1. Main Controller Board
   • Option A: Raspberry Pi Zero 2 W
     • Enough power to run some level of TensorFlow Lite or advanced Python scripts.
     • Wi-Fi/Bluetooth built in.
   • Option B: NVIDIA Jetson Nano (2GB or 4GB)
     • More AI horsepower, but physically bigger. Squeezing it into a 6-inch shell is extremely tight. Often used in advanced robotics.
     • Could be integrated offboard with a tether or custom enclosure.
   • Option C: Espressif ESP32 + External AI
     • Do motion control on the ESP32, and connect wirelessly to a more powerful offboard system that runs the AI.
2. Secondary Microcontroller or Smart Servo Controller
   • If using Dynamixel or LewanSoul servos, you can use their dedicated controllers or a standard board (e.g., Arduino Mega) with a half-duplex UART or a custom serial bus.
   • Servo HAT/Shield from SparkFun or Adafruit if using conventional PWM servos.
3. Power Distribution
   • For 12–15 advanced servos, you need a stable power supply (likely 7.4V LiPo or 11.1V LiPo stepped down to servo voltage).
   • Consider a high-current BEC (Battery Eliminator Circuit) or DC-DC converter that can handle 5–10A or more.
4. Batteries
   • 2S or 3S LiPo packs with ~800–1200mAh capacity for short run times. For high servo load, you may want 1000–1500mAh.
   • Charger: Must be a specialized LiPo balance charger.
5. Sensors
   • IMU (MPU-6050, ICM-20948, etc.): For orientation, acceleration, and basic hit detection.
   • Small Depth/ToF Sensor (VL53L1X): For distance measuring or potentially detecting an opponent.
   • Tiny Camera (OV2640 or similar): If you want vision-based AI 

Frame & Mechanical Parts:

1. High-End 3D-Printed Materials
   • Resin (SLA) printing for finer detail or Carbon Fiber Nylon (FDM) for higher strength.
   • You will need precise servo mounting geometry.
   • Optional: Use CNC-milled aluminum for critical structural parts if budget/weight constraints allow.
2. Linkage & Hardware
   • High-quality metal servo horns, ball-bearing joints, and miniature universal joints where needed.
   • Tiny screws (M1.6, M2, M2.5) with locknuts.
3. Armor/Outer Shell
   • Could be 3D-printed polymer for a stylized “Real Steel” look.
   • Possibly snap-on plates for easy servo access.

Approximate Costs:

• Servos (15x): $600–$1,200 total (using Dynamixel or advanced LewanSoul).
• Controller (Pi Zero 2 / Jetson Nano): $15–$150.
• Misc. Microcontroller Board / Controllers: $20–$80.
• Power System (Battery + DC-DC + Charger): $100–$200.
• Mechanical Frame & Hardware: $50–$300 (depending on materials).
• Sensors: $50–$100.

3. Build Phases

Steps:

1. Servo Bench Testing
   • Power a single advanced servo (e.g., Dynamixel XL-330).
   • Send position commands via a microcontroller or PC-based interface.
   • Check torque, speed, range of motion.
2. Simple Joint Prototype
   • Design and 3D-print a single arm or leg segment with 2–3 servos.
   • Test movement in free space to ensure no binding.
   • Confirm the servo’s load capacity is enough for your planned limb length and mass.
3. Electronics Setup
   • Select your main microcontroller (e.g., Raspberry Pi Zero 2).
   • Install the Dynamixel or LewanSoul library (or corresponding servo library).
   • Write a simple test script to move each servo from 0° to 180° (or min to max) slowly.

Phase 2: Advanced Prototype

Steps:

1. Full Robot Skeleton Assembly:
   • Print or CNC the entire frame.
   • Mount each servo carefully, ensuring alignment.
   • Route wiring (Dynamixels allow daisy-chain; LewanSoul uses a similar bus). Keep cables tidy.
2. Balance & Weight Distribution:
   • At 6 inches, every gram counts. Place heavier components (battery, main controller) near the torso center to aid stability.
3. Electrical Integration:
   • Attach battery + DC-DC converter, ensure stable 7.4V or servo-appropriate voltage.
   • Connect the microcontroller / Pi Zero 2 W with a servo bus line.
   • If using separate servo power lines, tie grounds together with controller ground.
4. Code: Basic IK & Pose Control:
   • For lifelike motion, use pre-defined keyframes or inverse kinematics (IK) for arms/legs.
   • Example approach:
     1. Define a series of “joint angles” for a punch, block, or idle stance.
     2. Interpolate between these angles over time to create smooth transitions.
   • Optional: Implement a small IK solver for arms or legs. (Libraries exist, or you can code your own using geometric approaches.)

Phase 3: Final Integration & Cosmetics

Steps:

1. Shell / Armor Plates
   • 3D-print or mold external shells to replicate a “Real Steel” aesthetic.
   • Ensure quick access for battery swaps and servo maintenance.
2. Sensor Integration
   • Install IMU in the torso (less vibration). Use extended cables as needed.
   • If using a micro camera or ToF sensor, mount it near the “head” or chest.
   • Make sure to calibrate the IMU for accurate orientation data.
3. Cable Management & Final Power Tests
   • Use braided cable sleeves or spiral wraps.
   • Double-check battery runtime under load. Possibly set up a “sleep mode” or minimal power usage approach.
4. Protective Measures
   • Over-current protection or fuses for high-end servos.
   • Use standoffs and rubber grommets to minimize mechanical vibration on the Pi or microcontroller.

Phase 4: Advanced AI & Combat Logic

Approaches:

1. Offboard AI + Onboard Motion Execution
   • A separate powerful machine (desktop PC or laptop with GPU) runs a real-time model.
   • It sends high-level commands (e.g., “punch_combo_1,” “block_high,” “sidestep”) via Wi-Fi/Bluetooth.
   • The robot’s onboard controller executes the servo motions for each command.
2. Onboard AI with Raspberry Pi Zero 2 W or Jetson
   • TensorFlow Lite or PyTorch Mobile for a small neural network.
   • A “state machine + neural net” approach:
     • State Machine handles sequences: idle -> punch -> retreat -> block -> idle.
     • Neural Net decides transitions based on sensor input (IMU hits, camera detection of an opponent’s move).
3. Motion Synthesis with IK
   • Implement a real-time IK solver to adapt foot placement or arm extension to varying conditions.
   • This is advanced but can produce more fluid “alive” motion.

Advanced Example: Reactive Blocking

1. The IMU senses a sudden jolt from the right side.
2. AI logic decides “opponent is attacking from right.”
3. The robot quickly transitions from idle to a “right block” stance by interpolating angles for the right arm.
4. Meanwhile, the left arm might prepare a counterpunch.

4. Iteration, Prototyping & Problem-Solving

1. Servo Overheating
   • High-torque moves in a tiny frame can overwork servos.
   • Solution: Add “rest” poses, limit maximum torque settings, or add small vents/fans if absolutely needed.
2. Battery Drain & Power Spikes
   • Many servos accelerating simultaneously can cause voltage dips.
   • Solution: Use a larger-capacity LiPo or add supercapacitors. Stage motions so not all servos accelerate at once.
3. Wiring Collisions
   • Tightly packed limbs cause wires to snag or pinch.
   • Solution: Route cables carefully, use custom cable lengths, add protective sheathing.
4. Balancing & Falling Over
   • A short robot is tricky to balance with high-speed moves.
   • Solution: Widen the stance or foot size, keep center of gravity low, or adopt smaller ranges of motion at the ankles and hips. Tweak servo speed/acceleration for stable transitions.
5. Software Bugs / Delayed Responses
   • Complex code for AI plus servo control can cause lag.
   • Solution: Optimize your loops, possibly use a multi-threaded approach or a real-time OS.
6. Mechanical Wear & Tear
   • Repeated punching motions at high torque can strip gears.
   • Solution: Use metal-geared servos or direct-drive brushless actuators. Periodically inspect and replace worn parts.

I'm 17 (U.S.) and I'd really like to try out robotics. Where do I start? My end goal would be to both construct and program robots. I am pursuing this for a couple reasons: 1) Interest. I just think it'd be a fun hobby. 2) I am considering a career in engineering and would love to see if I end up liking robotics, programming, circuits, etc... for majors I'm considering (the two I'm considering related to robotics are Electrical Engineering and Mechanical Engineering).

How do you guys build robots? Do you guys have specialized roles (like AI guys are different and the electronics guys are different, mechanical guys are different) or generally work on almost every aspect of robots? If I want to enter robotics then how much salary can I expect and what course should I study for masters? I feel like my mind is not focused on something particular in this field. My major is electronics and communication engineering and I have worked in an embedded systems company for 2 years. So I feel like I should be able to develop electronics part of the robot or otherwise I am not a good engineer. But just by building electronics a robot isn't built. It's only a dumb machine if there is no AI. So I also feel like I should dive deep into hardcore artificial intelligence and learn most difficult topics of it. What should I do can any of you guys help me out? Do people generally work as all round roboticists or do they work only on 1 aspect? Shoud I do a masters or a PhD? I am also looking to network with great people in this field

As I am an student of robotics and automation engineer as I decided to buy an laptop to learn 3d modeling and simulation should I go for the 2050 or 3050

Hi all, I am a computer science tutor, and I'd like to expand my offerings to include a 4 hour robotics class taught to 13+ aged students at a local adult education center.

To accomplish this, I need a good fit for a line follower robot kit that meets the following requirements

Programmable in ideally python, but c or c++ is acceptable

Quick to assemble

Tools required are minimal, ideally just a screwdriver or two.

Additionally, in order to hit my goal for tuition cost, I'd like to shoot for a budget of around 40 dollars a kit.

In my research, it seems like a decent line follower kit is around 65, but I'm wondering if this community knows of say, some open source kits (or easily sourcable parts lists) that would meet these requirements.

Thanks!

Hi everyone,

I hope this message finds you well. I recently came across a fascinating project where someone controls a small, remote-controlled robot to explore a city from a distant location when you control the robot in shanghai and another cities The robots is Are not like a normal tele-presence robot It's like a home/school made robot with a built-in camara

I believe this project was featured in a YouTube video when a person visits shanghai with that robot and visit a sewing shop and asking for something

And the last thing that i renember is that they have a discord server in that discord server you can control the robots and socialize with other persons and plan to visit another cities or give opinion of the cities that they visit

If anyone knows which project I am referring to or if they can mention several that are the same project, I would appreciate it.

Thanks

Hey, people

I'm trying to start a robotics project for portfolio, experience and to engage in robotics per se, cause I'm working in a engineering setting with small access to work with it.

My vision is to build a quadcopter in a simulation, to start to tinker around with different codes for path planning, sensoring, etc.

I've only experienced running ROS directly out of my physical notebook, with simulations in gazebo. But it is my intention to try running it with ros2 with a Docker/Windows setup in a fairly robust RAM/Processor PC

What would be my options for different simulation solutions? I've only known local simulators but have read about applications running in cloud servers. Are there any sensors, actuators, coding practice or other recommendations you could give me?

I am currently doing my second year in robotics engineering and i have to make a project on c++ as my end sem project. So I need ideas for c++ project based on robotics (as my domain is robotics).. but it should be more of a c++ project than a robotics project.. and I want the ideas to be advanced and challenging since it's for my end Semester.

Hello,

I am currently preparing for an exam, and I’m looking for examples of exercises related to the kinematic modeling of a 6-DOF spherical robot. Specifically, I need help with:

Direct Geometric Model (DGM)

Inverse Geometric Model (IGM)

Direct Kinematic Model (DKM)

Inverse Kinematic Model (IKM)

I am using the modified Denavit-Hartenberg method, and I would like to know where I can find similar exercises or solved examples to practice. If you have resources, examples, or advice, please share them with me.

Thank you for your help!

For a science fair im making an ornithopter to win one of the contest that will be held that day. However, I need to program the microprocessor (Esp 32) for it to work properly. It needs to take off, follow a route (at a certain altitude) and land. But this is my first time so could I get so help or a tutorial I could watch to get a better understanding

Title. Im an Electronics Engineering major. Ive had some basic programming knowledge(upto writing basic sorting algorithms, fibonacci etc) but i never really understood computers at a deep level. I originally wanted to study physics but that option is off the table now, so i wanna learn and dedicate my time on topics close to my field.

I started with the cs crash course by PBS studio and the explanation is amazing!! I found the working of the hardware very interesting and want to learn more about how computers and robots operate at a deeper level(Both software and hardware wise). Help will be appreciated
