gday everyone

for school i am going create a rc esky. i am basically going to make a metal frame with 4 wheels and sit the esky on top. though i need some help with the design of the steering. i dont know what to do. i would like to have it rear whell drive and the front wheels steer. it should be powered electronically. could anybody give me a tutorial to follow.

anything would be greatly appreciated

cheers

what i would suggest is your use 3 wheels to powered and one caster. instead of physically tuning the wheels use differential control

thanks for a reply.  i like your thinking. can you show me how i can use this without using tracks?

i mean, how do i get power to the rear wheels. plus, what sort of motor(s) do i need to push the weight of a full esky.
