Spring 2016 GRASP Seminar Series: George Konidaris, Duke University, “Robots, Skills, and Symbols”

April 15, 2016 @ 11:00 am - 12:00 pm


Robots are increasingly becoming a part of our daily lives, from the automated vacuum cleaners in our homes to the rovers exploring Mars. However, while recent years have seen dramatic progress in the development of affordable, general-purpose robot hardware, the capabilities of that hardware far exceed our ability to write software to adequately control.

The key challenge here is one of abstraction. Generally capable behavior requires high-level reasoning and planning, but perception and actuation must ultimately be performed using noisy, high-bandwidth, low-level sensors and effectors. I will describe my research on constructing robot control hierarchies through the use of learned motor controllers, or skills.

The first part of my talk will address autonomous robot skill acquisition. I will demonstrate a robot system that learns to complete a task, and then extracts components of its solution as reusable skills, which it deploys to quickly solve a second task.  The second part will briefly focus on practical methods for acquiring skill control policies, through the use human demonstration and active learning. Finally, I will present new results establishing a link between the skills available to a robot and the abstract representations it should use to plan with them. I will then discuss the implications of these results for building true action hierarchies.
