How should I get started with maze solver ?

Hey I'm interested in learning and building a maze solver robot but I'm not sure from where to start. I have some experience with basic electronics and programming (C, CPP and a bit of Python) and I'm part of a combat robotics club at my college. I want to understand the key components, algorithms, and design considerations for making a small maze solver using Arduino nano. Should I start with a simple line-following bot first? What sensors and microcontrollers would you recommend? Also, any good resources or beginner-friendly guides would be appreciated.

THANKS !!

Looking for BLDC motor

hi everyone, i am quite new to robotics, so i am not sure how i should look for something like this.

i am looking for a lightweight/small (like 3 cm diameter max) bldc which has relatively high torque. i want to be able to drive it in both directions. the application of the motors will be in being able to resist the rotational force of a finger, so i dont "need" much rpm. the torque should probably be something in the range of 2-4 kg / cm. does something like this exist? i am not currently satisfied with brushed motors as i get a lot of friction and the motion is not smooth. do you have any suggestiosn?

Window cleaning robot

Hi, I would like to buy a window cleaning robot. First of all are these robots good? Second I wanna buy a very good one, the budget is maximum $500. I have a house that has some windows upstaires that can't be opened, is there any way I can clean them easily? And also I have some windows that are very big. In conclusion, I want a robot that is very good and has a big battery since I have a lot of big windows.

Looking to get serious with a 3D printed arm.

I'm looking to get serious about learning kinematics, simulation and such with a quality 3D printed arm.

The one pictured is pretty cool for a hobbyist like myself, but I am looking to up my game.

Any good FREE 3d printed arms out there? Preferably one that you yourself have printed and built.

Thank you in advance.

How much AI are you guys using in your sideprojects?

With this rapid development with AI, agents and everything.

How much are you guys really implementing AI in your projects?

I find it difficult to really get done, tho im a noob in this. But are there any sources for AI with just software for robotics?

Looking for robotics project ideas for a bottled water company

Hi everyone,

I'm a student exploring robotics projects and I'm particularly interested in how robotics can innovate within the bottled water industry.I'm looking for something that I can build.

I’d love to hear about any experiences you’ve had or projects you’ve seen that align with these themes. Thanks in advance!

Fusion 360 tips

Hello everybody, I know this might be unrelated but specifically for robotics, Do you guys have any tips on fusion? I'm new and I want to know how to design better. Here is a question how do you design in a way where you can build it like it's built and split it up into components? Any other tips that really helped you in your experience would be great!!! I watched a couple YouTube videos but I like reddit more imo.

Career Option? Deformable object manipulation

Hey everyone, I’m a PhD student in robotics (from ME background) and was recently assigned to work on deformable object manipulation—things like handling soft objects (food or human body). The problem is, I really dislike contact mechanics, and my advisor isn’t an expert in this area either, so I don’t have much support.

This has been frustrating and overwhelming, and I’m starting to worry about my job prospects. I prefer industry research over academia or pure engineering roles, but this field feels like it’s still in its infancy. I’m unsure if there are good career opportunities for someone specializing in this area.

Currently I'm doing literature review and exploring RL and graph learning methods currently. I have a co-advisor from computer vision side, not exactly clear how much vision-based training I'll have access to. My primary advisor seems to not willing to let me to lean too much on vision side as he thinks his expertise is in ME therefore should be the focus which limit my ability to dive deep into vision-based approaches.

So, I’d love to hear from people in the field:

  • How does the job market look for deformable object manipulation in industry research?
  • Are there companies actively hiring in this area (robotics, AI, soft manipulation, etc.)?
  • Would it be better to pivot to something more established, or is this a valuable emerging field?

Any advice, insights, or personal experiences would be greatly appreciated! Thanks in advance.

Best Option to create a simulation environment for an AMR that just runs firmware

I am currently working on autonomous mobile robot at my work. All of its control is written in C as a firmware/embedded layer. However, we currently just have the single robot to test on.
I'd like to create a simulation environment for the robot without having to rewrite the entire codebase to use something like ROS nodes for me to use Gazebo.

Looking for ideas on either better/simpler ways to integrate ROS into our code and use Gazebo, or alternatives that offer better solutions.

Our robot code is running linux with a real-time kernel patch if thats relevant.

Robot reacts emotionally to pep talk about relationship with printer. This is autonomous behavior. All models run on the robot.

Got 2 profast motors from jsumo and each draws 5A+ at 7.8v in stall

Hello i got these motors https://www.jsumo.com/profast-12v-3600rpm-fast-gearmotor it says stall current its 1.2A and 150mah idle at 12V. But when testing i got 5A+ draw on each motor on stall and 600mah idle with my lab bench suply at 7.6V!! if i connect these to my robot its gona burn the power supply and motor drivers (4A max total consumption)... is there any way to use them?? (at 12v they burn my fingers)

Measuring device

Hey all, I’m looking to make a device for my job, essentially it will be servo motor attached to a ballscrew and linear guide with a stopper that I want to control and move to certain measurements. I’d like the stroke length approximately 1800 mm. I’m looking at a 2510 ball screw with a nema 34 servo motor. The only thing I don’t have a clue about is how to control it. Ideally I’d like a tablet or a smartphone to control it and i need it to move to whichever distance I put in the controller. If that makes sense lol

Alternatives to the dynamixels to make the low cost robot by AlexanderKoch

I want to make a desktop arm that is both cheap but still has decent usability. I come across this low cost robot by AlexanderKoch, but it uses 6 dynamixels which can be very expensive (for a college student). Is there any other alternatives like the feetech sts3215??

Starting to build an InMoov robot

Hello all, I'm new here so I was planning to start building the inmoov robot but I've some doubts regrading it. So like is their any complete tutorial articles or videos available online, and where should I get the CAD files I've checked their website but I haven't seen any good tutorials. Can someone help me to build it.

sort of an ELI5 question: using bots like Boston Dynamics Spot and UniTree Go, what are the challenges in getting it to auto recognize and throw away trash? Specifically confined areas like a construction site.

I am completely ignorant of the challenges in autonomous robotics. I assume there are several challenges or someone would have done it by now. If I was going to put together a fund to solve it, what are those challenges?

GPS Tracker Size and Weight Feasibility

I’m working on a robotics project that requires a GPS tracker small enough to fit inside a dart. Ideally, it would be no larger than 1 inch x 0.5 inch x 0.2 inch and weigh less than 10 grams. Curious to hear thoughts from anyone with experience in miniaturized electronics, GPS, or low-power tracking solutions. Would current technology even allow for this?

Anyone got an open-source Hidden Markov Model?

For context, me and my research group wanted to use CNN, RNN, and HMM as a way to translate slurred or unclear speech for speech impediments

CNN and RNN are sorted already, we plan to just follow a tutorial from Medium, since they're already conditioned for sound differentiation

However, I'm not really sure about HMMs, since, well, they're all GitHub links and me and my buddies don't know crap about machine learning (yet) so we have no idea if its reliable

So... anyone got a reliable HMM program that they are willing to share? I can assure everyone that we will properly credit your work, if, of course, it works

Thanks to anyone who can help
