Giskard

PDXBot.02 Summary
A programming error, quite frankly, was the competitive demise of Giskard. I allocated only half a byte to store the ground sensor contrast reading instead of an entire byte. The less glossy competition ring didn't register on its ground sensors, as the test poster ring at home did. I corrected the problem after the first match, only to forget to wait for the robot to flip down before calibrating the sensors. It ran out of the ring by itself in both matches.

As a fun fact, the tires are actually peanut butter lids with rubber bands wrapped around them. The servos are the same as from Junk and Just Big Boned, which get 90 oz./in. torque and have metal gears. It was named after a robot from Isaav Asimov novels.
