This week, I compare two different motor configuration as shown below.
The test is run under the setup:
A commander controls the blimp to touch both sides of the wall and then go to its starting position,
the time cost is recorded. Each configuration of the motors will be tested 10 times and the average time will be the evaluating result.
The mean time of first configuration (on the left) is around 31 seconds. The mean time of second configuration is around 38 seconds.
The reason of the difference is probably due to the fact that, for the first configuration, two motors play the role in forward motion while for the second configuration, only one motor controls the forward motion which may cause the speed to be different.
