Performance Test 1:

• Coding used absolute position (tick marks) and coasting for braking method
• Was inconsistent with braking distance; almost always missed first sensor
• Used less energy

Performance Test 2:

• Coding used absolute position (tick marks) and power braking for braking method
• More consistent than coasting, but still slightly inconsistent
• Used slightly more energy, but not much of a difference

Final Performance Test:

• While loops with long bursts of power and braking up the hills and short bursts on the flat surfaces
• Power braking to stop
• Coasting down the hills
• Once perfected, this was the quickest, most consistent, and the most energy efficient

Limitations:

• Battery voltage/ energy used
  • Battery decreases in power throughout the runs so we have to switch batteries
• Inconsistency in braking distance
  • Can be too short or too long when using the same code
  • Changed to a while loop and it worked better

• Inconsistency in different tracks
  • Slightly different lengths for different classrooms, so we have to change the code every time
