@jackwhirl yeah similarly, but each wheel is independent. and there is no steering column or pinion. The wheels are attached to the frame and pivot on an axis at the center of the wheel
How much force is required to turn the front wheel of a 4 wheel robot that weighs 200lb. Assume the wheel is 6inches wide, has a diameter of 12 inches (rubber). I would like to know how much force is required to turn a single wheel left or right when it is in stationary (non-moving) position...
