I would love some suggestions on keeping this WIP project from tipping over: (2 URLs) The tower stays together, with a technic beam running up the back side. But the whole baseplate flexs and tips over with the weight of the overhanging arm. And (...) (18 years ago, 27-Jan-07, to lugnet.build, lugnet.technic, FTX)

Hi Nathan, (...) the RCX rotation sensor should work on sensor ports like all legacy sensors, provided it is supported by the firmware. It would also be possible to build a rotation sensor for the motor ports, i.e. like a NXT motor without the motor (...) (18 years ago, 27-Jan-07, to lugnet.technic)

(...) 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)

(...) I would like to hope so. Those mounting holes would seem perfect to secure rubber cleats to, especially with the ridges on the hard plastic tread underneath. That one piece woulkd change them from semi-decorative to fully robotic functional (...) (18 years ago, 24-Jan-07, to lugnet.org.us.laflrc, lugnet.robotics, lugnet.technic)

Since they already have mounting holes, it only remains to figure (...) (18 years ago, 23-Jan-07, to lugnet.org.us.laflrc, lugnet.robotics, lugnet.technic)
