P-R&D #1: In this lab, basics of programming were applied and tested.
  1. There was slight resistance in the performance of the electric motors. When the program began, the wheels started out slow and then came up to speed.
P-R&D #2: In this lab, the reflective sensors were built and tested.
  1. Some of the commands in this lab may limit the success of the AEV in its completion of the scenario. For example, the brake command does not immediately stop the AEV. It simply turns off the motors and the AEV runs until it slows to a stop. Also, for the go to relative and absolute position commands, it is based off the calculation of marks. The calculations could be easily messed up so it is important to check work several times.

P-R&D #3: In this lab, the data extraction tool was used and the AEV was tested on the track.

Energy v. Distance

  • The AEV continually uses more energy until it has traveled a distance on 1 meter. After 1 meter, the AEV was no longer receiving power from the motors and using energy. However, the AEV coasts to a stop once the motors turn off. The energy levels off after 1 meter, which indicates when the AEV started coasting to a stop.

Energy v. Time

  • The AEV continually uses more energy as time passes. Once 8 seconds have passed, the AEV energy levels off. As with the Energy v. Distance plot, the leveling off of the energy is a result of the AEV coasting to a stop.
 
Power v. Distance
  • The power to the AEV increases until the power reaches about 5-6 watts. Then, the AEV moves forward with 25% power for about 0.12 meters and then decreases the power to 20% until the AEV has traveled about 0.36 meters. The large spike in the graph around 0.5 meters is when the motors reverse. After the motors reverse, the AEV travels at 25% power for about 0.5 meters before all power is shut off and the AEV coasts to a stop.

Power v. Time

  • The motors take about 4 seconds to accelerate to 25% power. Then, the AEV travels at 25% power for 1 second and 20% power for 2 seconds. The large spike in the graph at 6 seconds is when the motors reverse. After the motors reverse, the AEV travels at 25% power for 2 seconds until all power is shut off and the AEV coasts to a stop.
