My new project is to build a Mission Planner GPS-based tracker. With a fully operational set of gear for UAV + FPV , I bought a 6-Ch Maestro servo controller recently and followed the instructions in the arducopter wiki page, but it did not work. Here is my set up :–
- Maestro servo controller connected to PC USB port. 5V power is provided to the servo controller and 2 servos connected to Ch 1 & 2. All these are confirmed to work as witnesses in the Maestro Control Center.
- 3DR radio Ground Module with a directional antenna is connected to another USB port of the PC.
- A GPS USB dongle at 4800 baud rate is connected to the third USB port of the PC.
- A fully operational Video Rx hooked up to a monitor screen in a tripod.
a) I have not yet built the gimbal part of the tracker, so the servos are just lying on the table, loosely connected to the servo controller.
b) The GPS USB dongle has locked over 9 satellites and running as shown on the PC.
c) During testing, I powered up my quadcopter with a 3DR radio Air Module and connected to the Ground Module via the mission planner and there was heartbeat as confirmed in the PC.
d) After powering up everything, I opened up the Antenna Tracker page in Mission Planner, clicked on one of the 2 com ports for the Maestro Servo Controller, then clicked “connect”, the range figures for both pan and tilt all disappeared. By then, I have clicked both the “connect” buttons for the 3Dr radio MAvlink AND the Maestro Servo Controller. Is this correct ?
Now when I moved my quadcopter over the PC, the servos did not move.
Can anybody help ? Does the Video Rx matter, as the signal received by the Video Rx is only for the monitor screen ? Is there a mistake in my basic setup ?
Appreciate any help.
