the competition to encourage high school age kids to
participate and learn that technology can be fun as well as
useful.”
Here are some highlights from this competition. The
first robot to successfully navigate the course was Auton
made by Srinivas Raj (Figure 14). You can get extra points
if you don’t use a GPS to guide your robot. In fact, two
robots — built by the brothers, Nathan and Richard Burnside
— won their divisions by using dead reckoning on gyros that
were sampled at a 1 kHz rate and integrated with a 32-bit
value. Since their times were both around 20 seconds, the
gyro drift was negligible (Figures 15 through 17).
