Hmmm, indeed, or perhaps if we monitor the time it takes for a Leg to hit the
ground and then install a logic command that will take action if the leg does
not hit the ground in a predetermined amount of time. If the leg's foot sensor
does not detect the presence of solid ground within the time it normally takes
to hit the ground, it can be presumes there is no ground and this could be
managed and corrected. So when a foot does not "feel" the ground ahead of it in
a predetermined amount of time; the time it normally takes to hit the ground, it
can begin the self preservation/course reversal actions.
Could we still do this then?

Or install a command that will trigger the reverse seqence, should the foot not
send a tounch down signal within the expected arrival time.
cool right. I got my hand in the cookie jar.

| (...) Detecting the table edge is not the problem. We can do that with a sensor in the hip/leg in addition to one in the foot. Then, when the leg is extended, and the foot is not touching, there is an error. The problem (as I see it) is that it must (...) (21 years ago, 21-Apr-04, to lugnet.technic)
