(...) The more I thought about this, the more I liked this idea: I wanted to make a really high-mobility vehicle, but the problem with wheels is they are really stopped by steps greater than their own radius (well, partially, ignoring pushing from (...)

(...) Yes, and no. The problem is they are hard plastic with ridges, so if a tread ridge catches on a rough portion of the surface, they push fine... but if the surface is smooth, they'll just slide (very low coefficient of friction). The width is (...) (18 years ago, 23-Jan-07, to lugnet.org.us.laflrc, lugnet.robotics, lugnet.technic)

The second set of arms on Mike's robot gives it better mobility. They make its overall tread length much longer, so it can treat stairs like a ramp instead of, well, stairs, and that makes it faster at climbing them. The arms also let it raise the (...)
