(...) Thanks a lot, Rosco. I think I'm going to go with Stefano Prosseda's variation, which you also mention on your webpage (URL) clearly didn't quite understand the concept and now see how my design had way too many gears only to accomplish (...)

(...) snip (...) Here's yet another shrunken dual differential design. It uses worm gears to drive both differential housings as a space saving measure. This also the adds the feature (?) of a bit more gear reduction. There's a few pics of the (...) (23 years ago, 20-Mar-02, to lugnet.technic, lugnet.robotics)

(...) For ~US$32k I'm guessing that some slight enhancements could be expected. The section referring to its ability to sing was amusing - just give it the music and lyrics (ie - program it) and it will sing on demand. Yeah, I had an Amiga once, (...) (23 years ago, 20-Mar-02, to lugnet.robotics)

(...) Excellent color coding in your pics. Regrettably, I have no practical advice. When I built the differential drive in Dave Baum's book, I was dumbfounded by the principle. I look forward to to seeing what is clearly a demanding project. - Kyle (23 years ago, 20-Mar-02, to lugnet.technic, lugnet.robotics)

(...) Well, I think several people have delved into this, but here's my contribution (URL) It doesn't solve the "dual speed" problem, but it's fairly small, and can be reduced further. ROSCO (23 years ago, 19-Mar-02, to lugnet.technic, lugnet.robotics)

Hi all, I've got an intriguing little MOC coming up that hopefully will interest both the technicheads and the robogeeks. It is a tracked vehicle with a twist, but you'll have to wait to learn all the details ;-) In the meantime, here is something I (...) (23 years ago, 19-Mar-02, to lugnet.technic, lugnet.robotics)
