Re: How can we drive on this new floor?
One thing to watch for when designing the robot is turning ability when using skid steering (tank drive).
If you notice the coefficients of friction for the wheels, you will see that inline dynamic is .05 while transverse dynamic is .10. In a skidding situation the wheel will be twice as resistant to going sideways as it is to going forwards.... That means, as I read it, that your wheel is not going to want to slide sideways very easily if you use 4wd tank drive. In fact anyone planning on going with skid steering will probably want to really look at using at least six wheels to minimize the amount of skidding required in a turn. Jason
