Controlling AUX port with MAVROS #62

Open fselius opened 8 years ago

fselius commented 8 years ago

In order to drop the ball on target the Odroid needs to be able to control the AUX port of the Pixhawk. The mavlink command MAV_CMD_DO_SET_SERVO seems to do just that, need to figure out how to issue the command and verify that it does activate the servo.

Can we use this to change the camera position?

fselius commented 8 years ago

Yes!

noamyogev84 commented 8 years ago

i think this command should be followed with a param indicating which servo you would like to trigger.

fselius commented 8 years ago

Correct, it takes two parameters - the servo pin as you mentioned and the output value 1000 to 2000.

ok then. I'll implement it as a service call 'set_servo' is the string value. also, the channel number and the passed value (param1,param2) will be defined inside NavConfig.json.

fselius commented 8 years ago

Is it possible to set the passed values (param 1 & 2) when you call the service?

To activate the servo and drop the ball we'd like to call set_servo(param1 = 1, param2 = 1800), to stop the servo we'd like to call set_servo(param1 = 1, param2 = 1500). To change the camera orientation we'd call set_servo(param1 = 2, param2 = 2000) etc.

Yup

we need to keep in mind it might not be instantly, have to check it carefully

ball drop servo

guys, are there any configurations that need to take place in the mission planner regarding the servo? still stuck on that issue. http://copter.ardupilot.com/wiki/common-optional-hardware/common-servo/

is there any chance that the numbering of the channels are not 1-1? maybe aux 1 is channel 8 ? @serbuh @shadows89
