An ongoing focus of our group is developing machine learning techniques for robotics. Manually programming new robot behaviours is very challenging. A robot that can learn its own behaviours can better and more quickly adapt to new situations and tasks, without relying on domain experts and programmers. This learning is very beneficial for robots for home environments, as end users could instruct their robots to learn new skills, rather than rely and wait on teams of experts to design and implement new software.
We have developed several robot learning systems using learning from demonstration, explanation-based learning and reinforcement learning. Often these are combined, for example, using observations of another agent to create an abstract description of a behaviour and then using that to guide trial-and-error learning to refine the behaviour. This hybrid paradigm has been applied to locomotion for bipedal robots and rescue robots. It has also been used to learn how to use simple objects as tools, for example, learning that a hook shaped object can be used to retrieve another object that is out of reach of the robot’s hand.
