Omni on the cheap.

If I wanted to make an inexpensive omni/kiwi platform with the wheels perpendicular to a radius drawn from the center (like 229 and 867 did), could I control it by a standard RC (stick type) remote and use this http://robotcombat.com/marketplace_robotlogic.html (scroll to bottom of page) I know there's not much info on this thing, but from your take on it do you think it could control the 229 or 857 omni/kiwi bot?

And I can use this with regular ol' RC speed controls (forward and reverse type) right?

How would it work? If I have a two stick remote (think Vex controller) then one stick would be both axes for translation and the other would be only one axis for spin?


For more on the "cheapness" of this project I'm thinking I can run on inexpensive Chinese (Nothing against the Chinese) 9.6V drill motors @9.6V (500 rpm) and 4" dual transwheels (plastic). And since it is only 9.6V, maybe I can use a regular RC speed control for each motor. The one I found is rated for 16A continuous 60A peak? Is that enough? I'm thinking it would be for such low traction wheels and an overall weight <35 lbs probably. In RC terms the speed control is rated for a "15 turn" motor which would be a "mild modified" I know the drill motor is a little larger than and RC motor, but it does have more turns (probably in the range of 30). Do you think 16A continuous is enough?
