Exercise 4- Design Analysis Tool

Power (watts) Vs. Time

From time 0(s) to 3(s), the power increases from 0% to 25% using the ‘celerate’ function. The motors are run at this power for 1 second causing the flat line. The motor power then changes to 20%  using the ‘motorSpeed’ function. The motors run at this power for 2 seconds using the ‘goFor’ function.The power spikes after this because the ‘reverse’ function causes the AEV t0 stop and reverse directions simultaneously.  The motors then run at 25% for 2 seconds using the ‘goFor’ function. Lastly, the ‘brake function is used to brake all motors causing the power to go to zero.

Power(watts) Vs. Distance(meters)

The power Spikes before the distance reaches .11(m). This is because the AEV had to accelerate from zero and doesn’t cover much distance before reaching 25%. The Power roughly stays the same from .11(m) to .27(m). The distance changes at a similar rate. This is because the AEV reaches it’s 25% from the ‘celerate’ function then only changes to 20% using the ‘motorSpeed’ function for 2 seconds. the power then spikes because of the ‘reverse’ function and the motors run for 2 seconds. The graph before and after the spike are similar because they it only changes from 20% motor power to 25% motor power instantaneously. The power then falls to zero because all motors brake using the ‘brake’ function.
