CoaX (tm)
Robotic coaxial helicopter built for research and education


Features

The Coax helicopter is an open, cost-effective and easy to use system. Educational applications include' autonomous navigation, non-linear systems, system linearization, frequency domain analysis, estimation theory, Hardware in the loop (HIL), multivariate systems control dynamics modeling and identification.

  • 2 x dsPIC133, one for sensor data-fusion and one for control and communication
  • Two brushless motors for the main rotors and two servo moters for the swash plate-based steering
  • Control system through open-source API to give high-level commands
  • Simulate algorithms on ODE or Simulink simulators, and use exactly the same code to control the real helicopter
