|Powerful and Robust Quadrocopter Platform|
We're making a heavy-duty quadrocopter because our 3D Printed Quadrocopter is a little fragile. This one will be made from the aluminium tube frame we found in the Level 1 labs, but with new motors and electronics.
Current development is now being done by the ICRS IARC Team.
The code for the quadcopter is published here in the mbed database.
- Source of counter rotating propellers.
- We should get a RC style USB controller.

The quadcopter now flies and is stable. It will be used as a platform for our IARC Team to further develop it.

Gyro is replaced. Motors will now spin in a controlled way upon input. Propellers are mounted. It will be enough to look kinda cool at the freshers fair, but no flying. Estimated 6hrs work left until flight. Unfortunately 2 of the 18A ESC have been fried: 1 completely burnt a phase MOSFET, and damaged 2 others, on the ground rail. Another is also damaged in an unknown way, maybe the same. Both of them short the motor phases when not powered.
- Measure motor curve and derive linear regression to linearize motor output.
- Tune PID gains.

Soldered up wires to a battery connector, and elongated wires to the motors. Connected up motors ESC and battery. Tested motors.
- Gyro is vandalized and needs replacing.

Bought the propellers(3 sets). Should arrive on Thursday 29th October.

Bought a tap and die set, and mounted our bigger motors to the frame. They are mounted slightly offset from the centre of the aluminium tubing, as a result of the motor's base having an odd number of holes. This shouldn't pose any problems though since all motors are equally offset.
