Goal:
The goal of Performance Test 4 was to navigate to the antenna, turn it 90 degrees, return to the bunker, and push the button. Extra points were awarded if the robot could navigate completely to the upper level and back down. Five attempts were allowed for the performance test.
Scoring:
Touch antenna or its stand – 5 points
Turn antenna at least 5 degrees – 5 points
Turn antenna 90 degrees – 5 points
Press final button – 5 points
Bonus – navigate completely to the upper level and back down
Results:
The robot was able to accomplish all of the tasks, including the extra task, in the first attempt. In order to turn the satellite, a wooden block was added onto the the back plate of the robot and was positioned so that it extended out sideways from the robot. The robot was able to drive to the far side of the satellite, hook onto the corner with the wooden block, and then reverse so that the satellite would turn 90 degrees. Then the robot was easily able to navigate to the upper level of the course thanks to the weight modifications that were made to the robot after Performance Test 1. Using RPS checks, the robot was easily able to navigate to and press the final button. Click to view Performance Test Scores.
Analysis:
No improvements were made to the robot after this performance test because none were needed. The robot was successfully able to accomplish all of the tasks due to the addition of the wooden block and improvements made from previous performance tests. The only thing that was changed from this performance test to the competitions was the removal of the wooden block because the robot did not fit the size requirements. The block was not needed for the final competition.
