Auto Quad
Sept 2018 - Ongoing
This is a WIP The idea is to buy a cheap chinese quad and eliminate drift + stabilize + direct it using a camera placed on top. I'm using a Syma x20, a nanoquad with significant drift, yet relatively stable in altitude as it has a barometer, and a camera placed on my ceiling to keep the quad in field of view. So far,
  • Using an nRF24 + Arduino to send control messages to the quad.
  • An Aruco marker placed on top of the quad for pose estimation.
  • Meanshift/KLT for tracking whern aruco detection fails.
  • An oversimplified PID control loop to stabilize depth + position.
