Figure 1: Distance(Meters) vs. Power(Watts)

 

Figure 2: Time (Seconds) vs. Power(Watts)

 

In Figure 1, the motor power is increased from 0 watts to about 4.89 watts, a 25% increase in power. Then the power was cut to 20% for approximately 1 meter. After, the direction was reversed, the motors were increased to 25% power. After about 0.35 meters, the brake function slowed down the AEV for the rest of the run.

In Figure 2, Power increased at a fairly linear rate from time=0 seconds to time=3 seconds. The power then remained constant for 1 second, followed by a 5% decrease in power. The vehicle then remained at 20% power for 2 seconds until the reverse function was applied. The power spiked at time t=6 seconds due to the need to fight the forward momentum and reverse the AEV. After the vehicle was reversed, the power remained at 25% for about 2 seconds, until the brake function was applied, going another 2 meters before it stopped.
