Abstract
Thermal soaring, a technique used by birds and gliders to utilize updrafts of hot air, is an appealing model-problem for studying motion control and how it is learned by animals and engineered autonomous systems. This simulation-based deep-RL system reveals learning bottlenecks in thermal soaring, defines a new efficiency metric, compares learned policy to soaring vultures' data, and finds that trained network neurons divide into function clusters that evolve during learning, posing thermal soaring as a rich model-problem for learning motion control.
