Building a Fault-Tolerant RL Octocopter: Direct Motor Control for Motor Failure Recovery
By
noleary
Summary
Karolina Dubiel outlines her technical plan for building a fault-tolerant octocopter drone that uses reinforcement learning (RL) to directly command all 8 motors, bypassing traditional PID control loops. The goal is to enable the drone to sustain flight even when motors fail by giving the RL policy full authority to reallocate thrust. The project focuses on six unique failure classes and communicates directly over a serial link at 50 Hz.
