Go to Post In my opinion, I wouldnt want gifts or praise from people about my help to a robotics team, all I would want is a thank you, that would make all my hard work and efforts worth while and it would prove to me that I could actually be making a difference in the students lives - Mike Schroeder [more]

OHHHH. This robot's a square, I thought the left side of the picture was just cut off, and now it makes a whole lot more sense. Thanks!

And I think you're right, but I think it'd be a mess to get the powers ratios right, because you've got 2 wheels on the ground fighting one. The weight balance would have to be super weird, or there would need to be a lot of math with traction forces, power draw, motor controller and motor curves, and stuff so you could manipulate power ratios so the forward components cancel when you strafe(and the sideways components do when you don't).
