| | Great FLL Video
|

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 (...)

I'm not sure I understand what you mean by 'use locomotion' nor am I suer how a race would work, but your ideas are appreciated. I hadn't thought about not using electricity at all. The only train stuff I have is a couple of blue rails... another (...) (19 years ago, 9-Dec-06, to lugnet.robotics)

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, Think of it like a robot arm. You can't get the precise control without the onboard sensors. It operates almost like an extension of your fingers. Also you wouldn't be able to program autonomous routines. It also enables self centering on (...) (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)

Thanks for the offer. I hadn't thought about the programming yet. STil need to watch your videos to see how yours works. At the moment I'm trying to learn NQC. I thought the whole setup might be controlled with a single RCX (as appears to be the (...) (19 years ago, 8-Dec-06, to lugnet.robotics)
