Data Analysis

In the first part of test, the AEV are ordered to run 6 seconds with a speed of 25 and then reverse the motor direction and run 1 second with the speed of 40. The data recorded in the first running are too deflected so we abandoned them. The voltage of battery decreased about 0.10 voltage after each running, and the distance AEV travelled decreased as the decreasing of the battery voltage. In the second part of test, the AVE was ordered to run 5 second with a speed of 35 and then reversed the motor direction and ran 3 second with the speed of 40. The voltage of the battery decreased about 0.01 volts after each running. The distance AEV travelled decreased as the decreasing of the battery voltage.

 

Conclusion

After running two different codes on two different batteries the results showed that the batteries were fairly consistent and the voltage only dropped a very small amount. It also showed that our AEV design is efficient and does not provide a lot of stress on the battery. This will help us when the payload is added to the AEV to keep the battery lasting longer and stronger.
