What about an impact sensor that sits somewhere in the interior of the robot?
Something similar to whatever triggers car alarms and/or car air bags.
Perhaps one could be constructed using three touch sensors that would give a
good indication of where the impact occured.
This of course removes the possibility of stopping before the impact.

| One idea I was having was something like a ring that could shrink and grow, sort of like have four sections, two of which can slide into the other two, then, no matter what part you press on now, the whole ring compresses into a smaller diameter. (...) (26 years ago, 4-Dec-98, to lugnet.robotics)
