As soon as the robots step out in the real and uncertain world, they have to adapt to various unanticipated situations by acquiring new skills as quickly as possible. Unfortunately, on robots, current state-of-the-art reinforcement learning algorithms (e.g., deep-reinforcement learning) require prohibitively large interaction time to train a new skill. In this talk, we explore methods to allow a robot to acquire new skills through trial-and-error within a few minutes of physical interaction. More precisely, we elaborate on how model-based robot learning can be used in conjunction with the priors from simulators to allow relatively complex robots, such as a hexapod, to adapt to broken legs and fault in the sensors within a minute of interaction and accomplish the task.
