Week 12

We took the drone out for a test flight. This test flight did not include the arduino or the avoidance code at all. This test flight was solely connecting the sbus of the receiver into the RC of the pixhawk the ESCs are also fully connected into the pixhawk. However it wasn't successful as two of the motors was spinning way faster than the other two. Also, when the throttle is on a fixed position, the two motors that was spinning faster was increasing in their speed despite the throttle not being increased. We thought that it might have been the problem of the drone not on a flat surface. If it is not on a flat surface, the pixhawk will try to compensate for the tilting of the drone . To solve it, we tried looking online for solutions and it was to re calibrate the motors and pixhawk. We tried re calibrating the motor lots of times but however still was not able to solve the issue. We than decided to reset the whole pixhawk and to try again. Still, the issue wasn't fixed. We used a motor voltage tester to check if the motor was in working condition and the results showed that all the motors are working properly and spinning properly, giving the right sound. Thus, we had to look into other options. Next on the list was the ESC board, we borrowed the ESC from another group to test on our motors and still, we had the same issue, the motors were not spinning at the same speed. At this point, we were clueless on what was wrong as everything was tested individually and all worked.
