(...) You're kidding, right? It's almost impossible to build a geartrain using the chain that doesn't have tons of reversal delay. The links seem to be designed in such a way that they don't work well with technic beams and gears. I always have (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)

Dean, it's probably dumb luck that the two drives on the piece I'm working on have little slack. Yet, with LEGO beams and blocks you can't use every gear combination; there are published beam/block/plate combinations that let this or that pair of (...)

(...) If you use a tensioner arrangement, then it works OK. I haven't really played around with much more than simple weight tensioners (mostly for conveyer use...the catapilar treads are great for that!), but imagine you could come up with a (...)

(...) Believe me that I have tried a lot of combinations. Also your and my idea of "little slack" may be quite different. But it is true that I have never done an exhaustive study on the subject. I usually just give up on getting it perfect and rig (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)

I think it would be a much more painful experience to watch autonimous robots out there bashing away at each other. Both from an entertainment and philosophical level. From an entertainment standpoint, I imagine it would be painfully dull. Given the (...) (24 years ago, 5-Apr-01, to lugnet.robotics)

I came here to post about Robotica, but I should've known it was done already! But I'll still discuss it:) Dean, I agree completely. This is for entertainment, and not just entertainment for robotic designers, but for the public. I actually like (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

(...) It's not the unit price, but the primary motivation for Lego products: It's a toy for kids. Yes, it has found some applications in education and amateur robotics, but it's still a toy. To build exact mechanisms, you not only have to deal with (...) (24 years ago, 6-Apr-01, to lugnet.robotics)

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. [And I will (...) (24 years ago, 6-Apr-01, to lugnet.robotics)
