Differential wheeled robot simulator

This Processing application is ment to simulate a differential wheeled robot, very used nowadays. This app will be usefull in our Robotics Workshops!

Differential Drive Simulator in Processing

I missed the github class so here it is the good’old zip
Here’s the link to the repo, you’re welcome to contribute ;)

There are still a couple of enhancements on the list:

  • real metrics and scale
  • connect to motor encoders
  • record a path on the virtual world and let the real robot follow it
  • become real simulator of the arduino code used in our robotics workshops

The video is reproduced a lot faster than the program really performs  :p

Some control keys are available:

The overall program is quite simple to use, just pass the mouse over the joystick area to control the bot.

The program basically maps joystick values X and Y to a differential drive system where two motors are used to drive a robot.

There is also a representation of a robot and its path according to the motors differential rotation.
