I need help. I'm trying to take a steering wheel (w/o the pedals) and using a chicklet. I want the steering wheel to turn the robot 180 degrees left when the wheel is turned 180 degrees left. So for the right side. But not more than 180 degrees in any direction. The robot is a three-wheel design with two wheels being powered. I want the wheel to turn the robot in a tank form one wheel going one direction and the other going the other direction. Also I want to have a separate joystick next to the wheel to use only with the y-axis and control the forward and backward speed of the robot. I'm sorry if this may seem confusing but any insight on how to fix the problem will be greatly appreciated.
