Hello! I am a graduating chemical engineering student and our technopreneurship project covers assistive device for blind people’a independent navigation. We would like to ask for intensive advice whether our plans are possible in a technological scale. Thank you

Hii, i am not from the electrical background but I wanted to know if someone can get me the code that runs in Water Flow Sensor or place to find the code it will be helpful! thank you

The Robots are taking over 😳🥲 https://youtube.com/shorts/H2oJYfy_kg4?feature=share

Hello, this semester im in a analog electronic course and we have to work in a project during the semester, im looking for ideas for interesting, challenging but not impossible projects. I´ve been thinking about topics like power electronics, traction and stability control systems , propulsion control system (engines), telemetry systems, and if you can suggest something related to robotics (motor control, sensors, actuators) i would be really greatfull because i want to take my first steps in that field. As a restriction i cant usea digital electronics devices (that´s a different course)

For one of my hobby projects I need a way for sensors to locate one another in a small region ( distance small enough that GPS is essentially ineffective ). Let's say I have "Sensor A" and "Sensor B". From Sensor A, i wish to locate the angle and distance of Sensor B with respect to Sensor A and vice versa.

Are there any such sensors that do not use GPS ( ineffective over small distances ) or Cameras ( expensive ) ?

Also is what am trying to achieve possible with any other combination of circuitry or sensors ??

Thanks in advance ✌️

Im a high-school senior wiring up my first hockey robot. I don’t think the wiring is an issue because the motors are spinning and the controller is responding. the issue I am having is the function of each stick. I want the robot to use “tank” controls. When bound the left stick moves the robot forward and reverse. The right stick turns left and right but they’re inverted. I have spent all day trying to find a solution and it has been a MASSIVE headache. If someone could help me that would be greatly appreciated!!! I’m using a DX6E and a AR620.

So I have a RC truck with a PIXHAWK controller and a trailer with a metal detector and an old cellphone to capture data. I'm running missions to scan areas and pinpoint the GPS location of any hits. I lost interest but I'm thinking about resurrecting the build. The system is plagued with interference in that something is causing navigation precision problems. I have a ground station to fix the GPS variance but the system still has very poor tracking.

The Question is: What will help shield the sensors from noise. also, I have underground power lines where I live so that may be part of the problem. That is my guess but, I'm not sure of the source of interference nor how to shield it. I tried aluminum foil and an aluminum plate as well as a long mast on the GPS receiver....

I have a question for anyone who knows the answer, I bought a pneumatic actuator to just play around with but I cant mount it on anything because there is a rod inside the hole on the tail thread and I have no idea how to get it out, I have tried brute force and asking politely so I am out of ideas, if someone could help me ill be forever grateful

Hey, I am new here can I ask if anyone had experience using a dynamixel servo motor and is able to interface it with the Universal Robot 5 before? If possible can you share how and what circuits did you use to connect them together?

Hi everyone ,im stuck on a project.

My task is reading the magnetic field of negative cable of a DC tig welding machine with a magnetic sensor. (min 20 max 200 amps)

im using Arduino and reed relay and hall effect sensor. and i manage to see magnetic field on torch cable (+)

But i asked to see on magnetic field on chassis (clemp cable) (-). reed relay and hall effect sensor doesnt see that.

should i use npn capacitive sensor?

why reed relay sees magnetic field on positive cable. but doesnt see magnetic field on negative cable. whats sensor should i use to see.

i dont need to see the magnitude of magnetic field. i need just (1 and 0)

briefly

" Why does a reed relay sensor or magnetic hall effect sensor, which sees a magnetic field from the positive cable of a 100 amp DC welding machine, does not see a magnetic field from the negative cable"

thank you

I’m new to this thread and electronics in general. Trying to build my first line follower. All online tutorials mention IR Sensor. However, while trying to buy them online, i keep seeing products that mention IR Sensor for obstacle avoidance robot. My question is: are the IR Sensor used for line follower and obstacle avoidance robots the same? If not, any particular model number etc I should look for?

Does anyone know about the electronic equipments used to study the characteristics of glaciers and high altitude environment. I need to do a seminar on any topic related to electronics and recently I found intrest in mountains, glaciers, etc. I heard in a youtube video where some team used to place electronic equipment in the Himalayas to research purposes.
