Autonomous ballooning allows for energy-efficient long-range missions but introduces significant challenges for planning and control algorithms, due to their single degree of actuation: vertical rate control through either buoyancy or vertical thrust. Lateral motion is typically due to the wind; thus, balloon flight is both nonholonomic and often stochastic. Finally, wind is … [Read more...] about Reinforcement Learning for Outdoor Balloon Navigation: A Successful Controller for an Autonomous Balloon
