The team ran five test of Power and Coasting breaking. For simplicity, the team decided to publish the first two tests of both type. Looking at the graphs, we see that the coasting breaking is more efficient. By coasting, the AEV was able to travel a farther distance with less energy. A downside that is seen though is that Coasting is very unpredictable in the total distance that it travels. Along with that, it takes almost twice as long to stop with Coasting than it does with Power Breaking.
Although Coasting is more efficient, the other drawbacks that are present outweighs this one advantage. The team is deciding to go with Power Braking for the AEV project.
Power Breaking Code:
reverse(1);
motorSpeed(4,35);
goFor(4);
brake(4);
reverse(4);
motorSpeed(4,35);
goFor(1.7);
Coasting Code:
reverse(1);
motorSpeed(4,35);
goFor(4);
