Sparky was crated for the June, 2 2001 robotics competition (See Pictures) in San Diego (SDRS events). The event was to go around 4 obstacles and return to the exact starting position. There was an advance round in which the robot has to circle the obstacles and also come back to the same starting point. I only participated in the first event. The robot did OK, it got second place (Well out of 2 robots that enter the competition. Mine and Alex Brown). To determine the distance to the starting point I was doing dead reckoning and sonar reading in which I tried to mach the sensor values obtain when the robot first started. But the timing for the dead reckoning was off and the robot kept on missing the target. Well, there is always next year. Now I use the robot as an EBOT for the Robotics Society of Southern California.
Here is a detail explanation of how I build the robot and the algorithms.
