(...) 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)

(...) Nathan, Yes, there are ways to do just about everything you asked. I don't think the RC motors will run at full power when connected to an NXT (which can be done via conversion cables) Personally, I'd suggest gearing up one or more NXT motors, (...)

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)

(...) Awesome! Great videos! BTW if you want to know how to make bigger tires, try inserting old school 1" Lego tires into the crevices around the large grey "hula hoops" from the star wars kit. This will make tires at least 8" (20 cm) in diameter (...) (18 years ago, 24-Jan-07, to lugnet.org.us.laflrc, lugnet.robotics, lugnet.technic)

(...) Yes, and no. 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). The width is (...) (18 years ago, 23-Jan-07, to lugnet.org.us.laflrc, lugnet.robotics, lugnet.technic)
