My project involves a user controlled wireless robot where the user would draw the path the robot has to take, and this is then transmitted to the robot which then follows this path. Right now I am focusing on the hardware design, so I want to implement the robot following a preprogrammed path. Based on my knowledge I would have to use PID algorithm for this as the path could involve curves rather than just straight line. So I am assuming a robot chassis with an encoder and compass module should be sufficient for this? Any thoughts would be much appreciated. Also any help on implementing the PID algorithm. Thank you
