We're trying to figure out what motors to use to control our arm with the tube grabber on the end, and ran into problems. We tried using a window motor, and it could not lift the grabber on the end of a pole. We then tried two window motors and it still couldn't do it. They were both direct drive, no gearing.
So then we turned our attention to the fisher price gearbox, but couldn't get the motors in them. We'd stick the motors in and screw them in, but when we ran power to it it couldn't turn as if it was jammed. After playing with it for awhile we found that it only works in some weird position that doesn't allow you to screw the motor in. Has anyone else had this problem? we tried all the motors we had with the gear on the end and it happened with all of them.
The grabber is pretty heavy, But we are putting it on a weight loss program
EDIT: Without CIMs, if possible..
make sure to make it look really cool, it makes it easier for teams to remember you, which comes in handy for alliance selections ;) - Holtzman [more]
