Turning; easier one way or the other?

[Max Lobovsky]

You aren't wrong, but I believe FizMan was talking about a "crab drive". In that case, I'm not sure why you care much about tank steering because you can just turn your wheels to turn like a real car, or even cooler, move by translation by having all the wheels have the same orientation relative to the robot and changing that orientation.

[FizMan]

I wish Max, I wish. Unfortunately, the way I'm developing the drive, that's not possible. But the benefit of the crab drive is, assuming the game won't demand it much, we won't need to turn often.

[Max Lobovsky]

FizMan, That sounds like you are talking about translating, not turning. How would you move in more than one dimension without turning? By translating, I mean point all 4 wheels in the direction you want to go, and drive.

[FizMan]

Oh yes, we are translating for the most part. BUT... unless the game is beyond my scope of comprehension, I'm going to assume that being able to TURN the robot as well will be undoubtably required... (for example, orientating the robot so that your bar hanging hook is pointed in the right direction)
