I am building an autonomous electric vehicle that simply needs to travel a variable distance (8-12 meters) very fast (aiming for 3 seconds) with preferably +- 3cm error to the left/right.
I figure that I am going to need strong DC motors for this since speed is 10x more important than error. So I was wondering if I want maximum speed, should use 4 moderate DC motors (1 per wheel) like this:
or if I should use 1 really high-torque DC motor and have a 1-wheel-drive set-up ? like this
Also, I plan on using an Arduino to control the set-up and most likely an electronic speed controller.
Thank you for reading. =)
