Hacking a Toy RC Car Rx Board - Remote Controlled Raspberry Pi Powered Robot Platform


I am researching remote control methods for a Raspberry Pi based Robotics Platform for a Robotics competition in April next year. (Pi Wars).

Before I run off and purchase an RC Transmitter and Receiver and some RC switches as in this Instrucatble I thought I'd have a look at some of the junk I have laying around.

I have a couple of old RC cars that I dismantled a while ago and found this small Rx board on my workbench.

Turn your raspberry pi robot into internet controlled telepresence robot.

Hi guys, 

My name is Jill, and I've been working on an open telepresence platform (letsrobot.tv) for any kind of robot you can think of, and i wanted to open it up to more people. It's kind of a cross between telepresence and live-streaming. You can basically hook up any robot that can run our software to the site for anyone on the internet to control. We have an API & documentation to help you get started.

Raspberry Pi Project

Hey guys,

I'm starting out a project in which I want to build a Raspberry Pi Self Driving Robot. The basic tasks the robot will perform are:

  • Lane tracking using RPi Camera and OpenCV3 + Python
  • Obstacle detection with Ultrasonic sensor + input from RPi Camera(if possible)

The materials I currently plan to use in this project are:

Custom robot transmitter and a few robots (Rpi, nodemcu and arduino)

Hi good people!

I have alot of robotic projects,and now I'm trying to make the one remote to control them all.

I have a lasercut box with a raspberry pi 3 inside, with the original 7 inch touch display, there is also two 3 axis joysticks. The touch display will do everything that I can't do with the joysticks. I currently have a quadroped robot using Phoenix Code controlled with a PS2 joypad. The interfacing on the touch display will be made in Kivy and python.

PWM on High Current(amp) Actuators

I'm trying to move up into the category I originally got into robotics for in the first place: bigger buddies!

I have a Raspberry Pi I'd like to use to control some linear actuators, which are 12v and lift about 225lbs. I'm unaware of their amp usage: a search for similar rated ones said ~4-5A. They were purchased from an online auto parts place, so it's unlikely they'd know.

Raspberry Pi Dagu Rover 5 4WD driving issue

Hi there,

I'm very new to robotics & I'm having an issue getting the Rover Wheels to spin properly. I've been able to get it to turn only in 1 direction, but only 1 channel at a time. When I attempt more than 1 channel, either they both slow down drastically or 1 stops turning while the other spins very slowly. (I guess this is a sign of power drain)

Below are a list of the parts that I'm using:

OpenCV error - Xlib, libv4l2, VIDEOIO error

Hi, I tried 2 types of code, do you know how to solve that problem? :)

How to build your first robot?

Dear: LMR

Just to let you know guys it wasn't that long ago I asked my Dad if we could start a robot club at school. My dad brought it up to my princible and he did not have a problem with it. This robot club is probably going to teach people in highschool to build there first robot. I have no idea what robot I am going to teach highschoolers to build.

Serial vs I2C communication

Hi, please, can you tell me difference between I2C and Serial communication and which is the best for communication Raspberry Pi 2 with Arduino (T'Rex Controller). Thanks

Raspberry pi and robots

Hello I was wondering how good a of a platform the Raspberry pi is for robots. Is their anything special I have to download to the pi in order for it to communicate to the robot? Or does it have those features right out of the box.
