[thoughtful]

hey,

how powerful is the Denso-Window motor, and which motor do you guys think of the most strong one. Can a single Window Motor lift the whole robot up(130 lbs), if no than which one can. I know this is a lat to be asking this.

We had a mechasim that uses a single window motor to move an pivoted arm, with a light grabber, but when we hold on the ball the thing wont go up. But it works pretty good when not holding on ball. Also the arm is about 56 inch, but if we put the ball at about 30 inch it work okay. THe arm is mounted on a 60 teeth sprocket(drilled through and bolted) the window motor has a 20 sprocket so basically a 3:1 ratio. Any comments to help us on this, fast replies will be appreciated.
