LVBots Challenge 3.0 - May 5, 2007
Our fifth robot competition was held back at Rancho High School in Las Vegas. We had 24 robots competing in the 5 different events, including our new Dead Reckoning competetion.
The Best Of Show award went to Jan Malasek for Road Rage.
We would like to thank our sponsor for their gracious prize dontations:
 Pololu Robotics |
Mini Sumo Results
We had 9 entrants in the mini sumo event.
As we did last competition, the preliminary events were a chance for every bot to have a single battle with every other.
Then the top 4 from the preliminaries went on to a single elimination bracket of best 2 of 3 battles.
| Robot | Builder | Preliminary Wins | |
| 1st Place | Happy Jr. | Byon Garrabrant | 7 wins |
| 2nd Place | Ultra Violet | Jan Malasek | 7 wins |
| 3th Place | Invid | Jon Bosley | 5 wins |
| 4th Place | Borg | Kely Small | 6 wins |
| Striker | Josh Bosley | 3 wins | |
| Bucky 2.0 | Scott Garrabrant | 3 wins | |
| Flat Spat | Kely Small | 3 wins | |
| Dory | Jon Bosley | 2 wins | |
| Mr. Happy | Byon Garrabrant | 0 wins |
Line Following Results
We had 7 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.
| Robot | Builder | Best Time | |
| 1st Place | Jack Rabbit | Jon Bosley | 41.50 seconds |
| 2nd Place | Laser | Byon Garrabrant | 44.47 seconds |
| 3rd Place | Blue Lightning | Byon Garrabrant | 53.11 seconds |
| 4th Place | Quixo | Scott Garrabrant | 1:40.76 |
| What's That Smell? | Jan Malasek | DNF | |
| Mr. Wiggles | Nicholas Bliech | DNF | |
| Big Ugly | Candice Kamachi | DNF |
Line Maze Results
We had 4 competitors in the Line Maze event.
The first 3 bots showed a sign of realization of solving the maze, so all received the 0:10 bonus removes from their time.
| Robot | Builder | Time | |
| 1st Place | CD Mazer | Byon Garrabrant | 7.43 seconds |
| 2rd Place | Quoridor | Scott Garrabrant | 31.34 seconds |
| 3rd Place | Square | Jan Malasek | 1:08.92 seconds |
| Black Pearl | Kelly Small | DNF |
Pool Race Results
Our second Pool Race only brought 2 robots, but they bothg ran very well.
Bots started equally spaced around the track, and had to complete laps around the track, while hopefully passing other racers.

| 1st Place | Road Rage | Jan Malasek | 1:11.66 |
| 2nd Place | Dog's Pants | Ben Schmidel | DNF |
Dead Reckoning
We created a new event for this competition, a Dead Reckoning contest.
Bots needed to drive around 3 bottles without knocking them over, then return to the starting spot as accurately as possible, and as quickly as possible.
| Robot | Builder | ||
| 1st Place | Genesys II | Byon Garrabrant | 5.5" - 53.41 seconds |
| 2nd Place | Dead Vex | Eric | DNF |
