|

Hope this is not off-topic, but I have a 8735 motor. The problem is that in runs for a little while (on full juice from the battery box), but then stops. It is a new motor, but when I try turn the stem by hand, I couldn't (without pliers). Is the (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

(...) I've been trying to start up a local Lego robotics group to do something like that - but so far, response from parents in the area has been disappointing. (...) They certainly do seed the junkyard for *some* of the activities - in the rocketry (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

(...) I think they are already doing that. Watch Battlebots carefully and you'll see many of the contestants aren't using a model aircraft type radio control - but instead have a computer joystick plugged into a laptop. Once in a while you'll see (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

(...) I love this show also, they build 'robots' that have human computers, but they could be a robot easily, most of the time with a good enough software package. In the US version, there were brand new engines that had been installed on crashed (...) (24 years ago, 5-Apr-01, to lugnet.robotics)

(...) Yes, I've noticed this too - they like to run it through their fingers and make bracelets and whatnot from it. Perhaps it would be a good executive stress toy? :-) Jennifer Clark (24 years ago, 6-Apr-01, to lugnet.robotics, lugnet.technic)

(...) Lack of floating point support could also be a bit of a problem. You could try legOS. I think you have about 32k available for programs, and there are very few restrictions. You could also do all the hard work on a PC. It's pretty easy to (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

My 10 year old son used to tell the kids at school that he built Lego robots that could really drive around and do things and the other kids would roll their eyes and mouth "Geek...Nerd..." etc. Now they are *VERY* (...)

I must sadly agree with you, Steve... Though what Dean suggests would bring some real technological ingenuity to a drab genre, no fully-autonomous robotic device is going to beat a human-controlled telerobotic device for quite some time.
