Re: Tank Stearing - 4 wheel drive

Most of our weight is over 2 of the wheels. We found out that the
robot turns better when the weight is towards the front, therefore we are sort of stuck with running our robot with the weight towards the front. Question, If we would have kept the weight in the center of the robot, would the robot turn just as good in both frontwards and backwords configuration.

With the balance point midway between the front and rear wheels, the machine should behave the same way going forward and backward if all four wheels are alike. With the center of gravity near the center of the robot, you would need more power to turn, though. When turning a tank drive robot with wheels, you are sliding wheels sideways when you turn. By having a forward or rearward weight bias, you need less power to turn and can use "taller" gearing without tripping breakers and/or smoking motors.
