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

Current development is now being done by the ICRS IARC Team.


The code for the quadcopter is published here in the mbed database.

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.
