 | | How much can you shrink a dual differential drive? —Miguel Agullo
|
| | | 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)

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 (...)

I look forward to to seeing what is clearly a demanding project. - Kyle (23 years ago, 20-Mar-02, to lugnet.technic, lugnet.robotics)

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)
