Building a tug to haul around RV's (bumper pull trailers, 5th wheels, etc.). Looking at wireless driving control with camera. Don't know whether robotics are required or if off the shelf components will be sufficient. Tug will be four wheeled and use asymmetric power forward/backward to left/right wheels to steer. System will be driven with 12 volt DC power. I am a former software developer with good electronics skills so I am just looking for overview and guidance.
