(...) For our purposes, this may not matter. However, couldn't the rear wheels be steered with a reciprocator? So as the steering wheel turns to the right, the rear wheels start turning right, then turn back to the left? So at, say 1/4 turn, the (...) (25 years ago, 18-Dec-00, to lugnet.robotics)

Another problem with all wheel steering is the problem of "switch over." Honda had a prototype of an all wheel steering car which used the mechanism of turning the wheels in opposite directions at slow speeds for improved turning radius and turning (...)

It seems to me that the touch sensors have very different caracteristics. One has ~ 390 ohms and another ~ 480 when pressed to the bottom. Also, when pressed just gently, they seem to have a higher resistance. Is this correct? Is there anyone who (...) (25 years ago, 17-Dec-00, to lugnet.robotics)
