8. Coding Strategy: Final Results
Decelerating before every checkpoint
Quick breaking
Reduce energy consumption
Motor speed with and without R2D2
25% without cargo and 30% with cargo
Longer deceleration and shorter reverse with R2D2
Momentum
Reduce crashing
Clare
-Decelerating before each checkpoint made the vehicle easier to break while also reducing energy consumption. We were able to reduce both coasting and the high power needed to previously break.
-The motorspeed with the R2D2 was slightly increased to provide the needed force for the extra weight. This let the vehicle move quickly enough to complete the scenario in the allotted time limit.
-Finally, a longer deceleration command was used on the returning half of the trip. This was because if the AEV stopped too quickly, the R2D2 would still have a forward momentum and would possibly crash into the AEV. Additionally, the longer deceleration allowed for increased efficiency by being able to have a shorter reverse motorSpeed command.
