I've just received a 2nd hand lego motor (peeron #71427), and to my surprise and (... well let's leave it at that) it's jammed. I remember seeing a website that showed the internals and possibly a way to solve this (except for complaining to the (...) (19 years ago, 11-Dec-06, to lugnet.robotics)

(...) Thanks for the heads-up about this! (And also the pointer to the v1.04 firmware update, too!) It is amazing how far TLC has come since the early days of the RCX.

I saw this video of New Hampshire's state champion FLL team, the Flying Geeks. They flawlessly accomplish all of the missions -- the robot even makes a pit stop back at the base to pick up a new tool without the kids snapping it to the robot. Check (...)

Hey John, That's a really nice bot. I'd like to write an NBC program to make it autonomous using the Ultrasonic sensor. Have you thought about posting building instructions or at least pictures showing how you built it? Dave (19 years ago, 9-Dec-06, to lugnet.robotics)

I see your point. Trouble is I don't have a 2nd RCX nor any real rotation sensors. Using the speed computers doesn't allow me to know if I'm rotating forwards or backwards. Still the device is impressive enough to give it a try. I'll just go with (...) (19 years ago, 9-Dec-06, to lugnet.robotics)

Hi, It occurs to me that if you use a pair of rotation sensors to manually control the structure the sensors that are embedded into the structure aren't really necessary ... or are they? What if you simply included a couple of clutches to protect (...) (19 years ago, 8-Dec-06, to lugnet.robotics)
