Formula for controlling the movement of a tank-like vehicle?

Question

Anyone know the formula used to control the movement of a simple tank-like vehicle?

To \'steer\' it, you need to alter the force applied the left and right \"wheels\

Answer 1

It's not a matter of force - it depends on the difference in velocity between the 2 sides, and how long that difference holds (also the tank's width, but that's just a constant parameter).

Basically, you should calculate it along these lines:

• The velocity ratio between the 2 sides is the same as the radius ratio.
• The tank's width is the actual difference between the 2 rasiuses (sp?).
• Using those 2 numbers, find the actual values for the radius.
• Multiply the velocity of one of the sides by the time it was moving to get the distance it traveled.
• Calculate what part of a full circle it traveled by dividing that into that circle's perimeter.
