One 12v, 3 amp (no load) motor with 6in wheels.
I'm building a 4WD robot, but I'm a little confused about how to optimize the robot for turning. I need to turn the robot 90 degrees, and I need the center of the robot to stay in the same spot as it turns. Anyway, were should I place the wheels? Should I put them far from each other, or as close a possible? The Robot will be 2ft wide and 3.5ft long.
Ideally, you would also be able to angle the wheels such that they tracked the circle as the vehicle turned in-place
than possibly not sure if you have the access to scrap wood or not but you might want to make a couple of wood platforms with those dimensions and test different mounting positions for the wheels that way when you found a place that works with the radius you want you will have the measurements and everything
The best orientation… wheels are at the extreme corners of a square base
Regardless, it really tears up the ground, and if used on hard surfaces
I posted the link to them above, but I will post again. http://www.parallax.com/product/27971
This looks good on paper but the device seems to be under revision which sounds bad to me.
If turning is difficult, the bot might be hinged in the middle and rotated left/right to help with turning. Another setup below.
