I'm looking for a sonar based tracking unit to make some thing follow me around. I was thinking of making something to pull around 140lbs on a cart for a school project. Maybe a library book cart that follows a person around. I'm great with hardware but this code stuff I just don't have a grasp on just yet. I thinking of using electric wheel chair parts like a jazzy power chair. 2, 12v 12AH batteries one for each motor.
Thanks for your help.
