FIGURE 14-15 Internal view of Live Wires showing the symmetry of all of its internal components. (photo by Clare Miles) of the battery box. This entire robot was bolted together using button-head screws to allow for easy maintenance. Finally: The Show Chapter 14: Real-Life Robots: Lessons from Veteran Builders 325 We stripped the robot down and shipped it to the TLC studios in seven different boxes. I decided to send it priority overnight a day before the last drop-dead day, which turned out to be a good thing because we had a major earthquake that brought everything to a standstill two days later. Luckily, the airport reopened the day before I was to leave for California, and I was able to get a flight. Dave and I arrived at the studio about 4:00 in the afternoon. We spent that evening watching the previous contestants compete, getting interviewed for TV, and reassembling the robot. Finally, we got to bed about 3:00 in the morning. Four hours later, we went back to the studio for the weigh-in. Figure 14-16 shows a picture of the robot at the weigh-in. I was originally targeting the robot to weigh around 100 to 120 pounds, but the robot came in at a svelt 198 pounds. A bit heavier than I thought, but it was still under the 212 pounds max weight limit. Because Robotica invited more robots to the show than they needed (in case of any no-shows), they had to come up with a qualification round to narrow the number of robots to 24. The first part of the qualification round was to go around the figure-8 course twice and get timed for the run. When our turn came, we put the robot in the arena and it took off. Figure 14-17 shows Live Wires coming around the first bend in the course. At this point, the robot started having problems. One side of the bot stopped working so it started going around in circles. This was a rather disconcerting experience. After the time expired, we gathered up

FIGURE 14-17 Live Wires running through the figure-8 qualification course at the first season of Robotica. the bot and took it apart to figure out why it wasn’t working. It seemed to be missing a beat when trying to drive. So we removed the 30-amp re-setable fuses that came with the Victor 883. Then we started to test drive the robot. It seemed to be running much better, and the momentary power losses seemed to go away.
