Lego Mindstorms

[Ben Mitchell]

I used the pregeared 9V motor that comes with the mindstorms kit. I have it hooked via axle extnder through a worm gear in a gearbox, driving a 24 tooth slip gear (the wierd white one) I also have a rotational senser hooked up on the same axle as the worm gear.

I don't know if that will slow the motor down. its doing a heavy amount of stuff, but I figure the sensor woulds be most accurate with as many rpm's as possible.

You might wonder why. I built a model of last year's robot with mindstorms. the moter in question is driving a long shaft of toothed plates, and a claw which opens as closes using rubber bands and a wedge.

Thanks for any information.
