A redundant flight recovery system implementation during an octocopter failure

Abstract

This research presents a redundant flight recovery system during a motor failure in an octocopter platform. This proposed recovery system exploits the property that the octocopter can be derived by combining two quadrotor systems. During motor failure, the octocopter switches to a stable quadrotor flight configuration while immediately landing the octocopter to prevent further damage to installed sensor and equipment and the octocopter platform. The redundant system utilizes PID and fuzzy logic controllers to stabilize altitude and attitude respectively.
