I used 6 servo motors, if you have a loose and smooth cube, very little force is required to turn it.
Here's a link to the one I did: http://www.eecs.umich.edu/courses/eecs373/Labs/Web/W05/Rubic%20Cube% 20Web/index.html As long as it turns faster than 1 turn per second should be the basic goal. I had to go into and mod the motors to do what I wanted though... and there's nothing wrong with over-volting them a bit :0. I had it run a human method (CFCE), but if you can implenment an optimal solver, that would be great. Are you planning on doing color recognition too? -Doug --- In [email protected], "invisible000man" <[EMAIL PROTECTED]> wrote: > > hi, > my friends and i are planning to attempt to build a cubing robot.... > > we were just wondering what motor would be good? > logically, we were thinking that a low rpm, high torque motor would be > preferable, but we aren't sure about the numbers (like specific rpm and > torque values) > > also, does anybody happen to have an estimate for how much it will cost > to buy all the supplies necessary to build the most rudimentary cubing > robot?
