The MultiWiiCopter is a open source software project aiming to provide the brain of a RC controlled multi rotor flying platform. It is compatible with several hardware boards and sensors.

The first and most famous setup is the association of a Wii Motion Plus and a Arduino pro mini board.

List of supported features:

• multi Rotor type
• BICOPTER
• TRICOPTER
• QUAD +
• QUAD X
• HEX Y6
• HEX FLAT +
• HEX FLAT X
• OCTO X8
• OCTO FLAT +
• OCTO FLAT X
• Gimbal
• when associated with an accelerometer, MultiWii is able to drive 2 servos for PITCH and ROLL gimbal system adjustment
• the gimbal can also be ajdusted via 2 RC channels
• Camera trigger output
• a servo output can be dedicated to trigger a camera button. A servo travel pattern is defined in this case
• GUI:
• Coded with processing, java core: Linux/MAC/PC compatible, USB connection
• exhaustive parameter configuration
• graphical visualization of sensors, motors and RC signal

• Flight mode:
• one of the following mode
• angle velocity driven (accro mode)
• absolute angle driven (level mode)
• optional mode, compatible with the 2 previous one
• altitude assisted mode (baro mode, compatible with the 2 previous mode)
• head lock assisted mode (magneto mode)
