While we're talking about programming rovers, could someone give me an
example of a 'spiral drive around behavior' in either RCX Code (v1.5) or
Gordon's Brick Programmer? Or how about code with two rotation sensors
attached to the differential-drive robot's wheels which drive straight
forward a certain # of clicks,clears the count, turns left 90 deg., clears
the count, goes forward a little bit more, clears again, then turns right 90
deg.?
My last attempt had the robot track pretty well straight for 100 clicks, but
when I tried to get it to reverse both wheels from 100 to zero, only one
wheel responded.
Can anybody help?
Regards,
