APM Quadcopter Autonomous Flight

I and my friend Jaeyoung tested GPS Autonomous flight mode of APM with two quadcopters which embed APM boards.

One embed APM 2.6 board and another embed Pixhawk board. Both uses ArduCopter firmware. A mission of Auto-flight is taking off from launch site – moving to waypoint – hovering for 2 minutes – returning to launch site.

Constant Yaw Rate Quadrotor

A new flight mode was implemented on to the modified Arducopter firmware that is capable of maintaining constant yaw rate while the quadrotor is able to be controlled by the pilot in respect to the inertial frame. Such a flight mode can be used in localization applications (SLAM) or imaging. Sensors that have a narrow…
