Hello, I'm at the point now where I need to get rechargeable batteries for the RCX. The alkaline's are just now making it anymore.

I think that my "Smart Acrobot" was pretty creative. :) I took the LEGO Acrobot that can flip over and keep driving and added a light-proof box with a light sensor and a handful of yellow bricks inside of it. This way, the light sensor either sees (...) (25 years ago, 31-Jul-01, to lugnet.robotics.rcx)

Hi Jeff, Tell me more about your fuzzy logic line follower. My line follower was always losing track of which side of the line it is on and turning in the wrong direction. It would then stop and use an expanding sweep based on the ideas of Dave (...) (25 years ago, 31-Jul-01, to lugnet.robotics.rcx)
