The most important feature of a competition robot is its reliability. This is how often the robot executes successfully what it is meant to do.
You will see us using reliability and consistency interchangeably. They both measure the success rate of a robot doing the same task over and over.
You must measure your competition robot consistency for every program that you create.
The method is as follows:
- Start the program 10 times.
- Count the successful attempts. The ones that achieve the end goal without errors or penalties.
- Divide the number of successful attempts by the number of attempts. Multiply the result by 100.
- The number you got is the percentage of success rate that you measured for your robot.
You can even assign a grade to your robot or program using the percentage you calculated, following the table:
- A 89% - 100% (9 or 10 successes out of 10 tries)
- B 76% - 88% (8 successes out of 10 tries)
- C 63% - 75% (6 or 7 successes out of 10 tries)
- D 50% - 62% (5 or 6 successes out of 10 tries)
- F 0% - 49% (0 to 4 successes out of 10 tries)
