Ardu Gaui Copter

Posted by AVS on September 12, 2010 at 7:30am

Waiting for my new copter legs I decided to see how the Jani copter could be adapted. The frame fits very well on the Gaui. I still have parts to add to the top but it works. I tried larger motors and 10" props but I need to raise two of the motors for this to work. So the picture shows the standard 10a esc and Gaui motors

Sonar and IR to follow. I liked the esc calibration of the Gaui so I have implemented this in my ardu copter code. This means the copter will not start if you have never calibrated the esc's and after that will not start if throttle is not in the lowest position.

Next job automatic PID adjustment!

    i manage to change the whole APM and olipan but now i cannot arm the motors. Weird. When i have done calibration and follow all the procedure. All change need to be done on the Alpha_rc1 code

    What pid values did you set?

    Did you calibrate each esc as per ardupcopter wiki?

    I manage to do arm and configure using configurator. But it went wild when take off, it wil flip over and crash immediately after take off? What could happen?

    By the way, be careful when you arm the motors with AP. It will spin the props. Hold throttle lowest most left to disarm

    AP is armed by holding throttle to lowest most right position for 200ms

    I have a Gaui 330xs setup and decided to plug in ardupilot mega for better perform. But the esc and motor seems to be not working when connected to the mega.

    I have follow the calibration for each esc (all motor and esc is working with rx) but when plug in to mega no respond from the esc. Unable to arm the motor too.
    Can help me?

    Unfortunately one of the esc and morors packed up before I got any stablility that why I would like some auto pid adjustment system :) I thought about fitting 10" props but it would mean two props have to be raised due to overlap. If you do get a stable system I will be keen to hear about. Best of luck

    i have this setup but I ca't get a stable flight. can you tell me you pid setting please

    I am skilled at breaking things and crashing so maybe well qualified :)

    It won't be easy but maybe this is a start? ...

    I thought there should be a clibration flight mode, where the copter gradually/gently tests the lift generated by each motor at various heights. The first height would be ground based for lift off. How much power to each motor causes what giro/accel movement? It might be difficult because close to the ground there is a lot of turbulence.

    The calibration mode, if possible, might have the potential to become quite sophisticated and, subject to cpu power, automatically integrated into all flight modes.

    Maybe I am dreaming :)
