(...) The NXT motors have built-in rotation sensors, so you could detect a stall condition with no other hardware. You could use the ultra-sonic (distance sensor) or light sensor to detect when the blade passes in front of it, to determine when the (...) (18 years ago, 26-Jan-07, to lugnet.technic)

(...) Thanks Steve for the information and the advice. Although gearing up the NXT motors may result in a loss of torque, it sounds like a good option. Another option might be to control the switch for the RC motor with one of the NXT motors (which (...) (18 years ago, 26-Jan-07, to lugnet.technic)

I bought the Mindstorms NXT kit at BrickFest 2006 in hopes of designing a Lego chipper. Although the sensors would make the design possible, the blade of a chipper has to turn at an extremely high RPM- and with a lot of torque. The NXT motors turn (...) (18 years ago, 24-Jan-07, to lugnet.technic)

The problem is they are hard plastic with ridges, so if a tread ridge catches on a rough portion of the surface, they push fine... but if the surface is smooth, they'll just slide (very low coefficient of friction).
