The goal of the LeTourneau Autonomous Robotic Competition (LARC) senior design team is to design and build an autonomous robot to enter into the 2015 IEEE Region 5 Robotics Competition. The competition is held at the annual Green Technologies conference with the goal of bringing academic, industrial, and other areas together to focus on environmental issues. The robot must comply with the competition rules, and the robot must complete the task 100% autonomously.
The following restrictions are required for all robots that enter the competition:
Challenge: The challenge has two parts in each round. The robot must perform part 2 immediately after part 1. A team member shall have 1 minute to set their robot before each run.
Part 1 - The robot searches the maze to find the shortest (critical) path from start to end within a fixed time limit for each round. During the search, the robot scores points by entering new squares and by identifying easter eggs. Easter eggs are symbols on the walls. They may be letters, numbers, or other special characters. Identifying and reporting easter eggs earns points in the qualifying and final rounds and additional time bonuses are also earned in the final round (see scoring).
Part 2 - If the robot completes the maze in part 1 within the allotted time (i.e. the robot makes it to the end cell of the maze) and then lights a red LED, the robot will be allowed a critical path run. In the critical path run, points will be awarded for correct moves along the critical path and deducted for moving off the critical path.
Scoring - Qualifying rounds (1, 2, 3)
Scoring - Final
Robots will advance to the final round based on their success in the qualifying rounds. Qualifying round 1 is a 5x5 maze. Qualifying round 2 is a 6x6 maze. Qualifying round 3 is a 7x7 maze with a few speed bumps. The final round is a 7x7 maze with more speed bumps than the third qualifying round. To determine the winner of the final round there are specific tiebreaker rules outlined below.
