LVBots Challenge 3.5 - Dec 1, 2005
Our sixth robot competition was held back at Jack Lund Schofield Middle School in Las Vegas. We had 28 robots competing in the 6 different events, including our new Walking competetion.
The Best Of Show award went to Bruce Romeo for Disco Boy.
We would like to thank our sponsor for their gracious prize dontations:
 Pololu Robotics |
Line Following Results
We had 13 robots competing in this event.
Robots had to make 3 laps around the track without falling off, and were given 2 chances to do this.
We started with preliminary races to determine the top 4, and then had a single elimination bracket to
pick the winners.
The line following track had 12 straight tiles, and 24 curve tiles, for a total 3 lap length of about 2821 cm.
