Do I have to buy the batteries seperatedly? How long can they last? Want can the robots do since they are so basic not like r2d2, c3po...? I whould like to read some ideas for this RIS 2.0 set specially. (...) (22 years ago, 20-Nov-02, to lugnet.robotics)

(...) Power-to-weight ratio's are far too poor. Electric-powered aircraft have to be built with very careful attention to battery and motor technology with the lightest possible designs. Lego is HEAVY - so no aircraft. (...) Yes - that's fairly (...) (22 years ago, 21-Nov-02, to lugnet.robotics)

One idea that I always wanted to persue was autonomus car racing, nascar style. I thought of setting up a small oval on a 4x8 sheet of plywood and marking the entrance to the corners in one shade, inside boundries(3' from the wall) in a second shade (...)

Now that's a well cool idea! We could set up 'formulas' based on the parts usable by the cars and the programming allowed, something like Formula 3 - standard RIS kit only, regular/NQC RCX code Formula 2 - standard RIS kit only, any (BrickOS, QC, (...) (22 years ago, 22-Nov-02, to lugnet.robotics)

(...) Good idea! I was thinking more in terms of bumpers but taillights and forward pointing light sensors is much better. That would allow a robot coming from behind to setup a pass without hitting the robot in front. Perhaps the sensor input used (...) (22 years ago, 23-Nov-02, to lugnet.robotics)

In general, I don't know how to use the list of inventions on mindstorms.lego.com. All I get is the idea that yeah someone did this and that.

Hi Steve and everyone else, I'm working on a Lugnet page with more information on my helicopter but in the mean time, here are the photos: (URL) you can see, I use a low-torque, hi-rpm motor with a non-lego rotor.
