HI all,

Major progress last night on the drop off sensor array. We put four GP2D120 sensors on the robots bottom, about an inch in front of and behind the wheels. These route to two 12F675 PIC's which have the a/d converters, and are really cheap. Right now, I sample the sharp sensors, which are remarkably uniform and when a drop over 2 inches occurs on any of them, for now an LED lights. This will then be ported into the Bumper/Impact module which has a very high priority in the arbieter. Thats later this week. For now, I can push the bot over an overhang on a table, and the corresponding LED will light indicating the drop off. Will the robot be able to stop in time to prevent certain death? Stay tuned!
