The use of a spring loaded system using rubber bands or such would be
a good idea for two position systems. But I can't think how to do it
for transmissions like my current two that four positions.
I think I'm going to try a motor with a worm gear pushing the lay
shaft back and forth in my first design.
The second transmission needs something more akin to a clock
escarpment to lock it's rotating part in each of the four positions.
Still working on it... :-)

Each spoke ends with a free to move wheel (the axis of the wheel is arranged (...) (25 years ago, 16-Feb-99, to lugnet.robotics)
