Robots think with their hands
The design of cognitive situated robots able to learn to operate in the real world and to interact and communicate with humans, must model and reflectively reason about their perceptions and actions in order to learn, act, predict and react appropriately. Such capabilities can only be attained by embodied agents through physical interaction with and exploration of the real world and requires the simultaneous consideration of perception and action. Representations built from such interactions are much better adapted to guiding behaviour than human crafted rules and allow embodied agents to gradually extend their cognitive horizon.
In the first part of the talk, I present the concept of Object-Action Complexes (OAC, pronounced “oak”) which has been introduced by the European project PACO-PLUS (www.paco-plus.org) to emphasize the notion that objects and actions are inseparably intertwined and that categories are therefore determined (and also limited) by the action an agent can perform and by the attributes of the world it can perceive. Entities (things) in the world of a robot (or human) will only become semantically useful objects through the action that the agent can/will perform on them. The second part of the talk presents current results toward the implementation of integrated 24/7 humanoid robots able to 1) perform complex grasping and manipulation tasks in a kitchen environment 2) autonomously acquire object knowledge through visual and haptic exploration and 3) learn actions from human observation. The developed capabilities are demonstrated on the humanoid robots ARMAR-IIIa and ARMAR-IIIb.
Tamim Asfour is senior research scientist and leader of the Humanoid Research Group at Humanoids and Intelligence Systems Lab, Institute for Anthropomatics, Karlsruhe Institute of Technology (KIT).
His major research interest is humanoid robotics. In particular, his research topics include action learning from human observation, goal-directed imitation learning, dexterous grasping and manipulation, active vision and active touch, whole-body motion planning, cognitive control architectures, system integration, robot software and hardware control architecture, motor control and mechatronics.
He is leading the system integration tasks and the development team of the humanoid robot series ARMAR in the German Humanoid Robotics Project (SFB 588) funded by the German Research Foundation (DFG). He is currently involved in the following projects funded by the European Commission: PACO-PLUS, GRASP and Xperience.
Tamim Asfour is member of the Editorial Board of IEEE Transactions on Robotics and European Chair of the IEEE-RAS Technical Committee on Humanoid Robots. He is member the Executive Board of the German Association of Robotics (DGR: Deutsche Gesellschaft für Robotik). He serves as member on several program committees and review panels.
He received his diploma degree in Electrical Engineering (Dipl.-Ing.) in 1994 and his PhD in Computer Science (Dr.-Ing.) in 2003 from the University of Karlsruhe. In 2003 he was awarded with the Research Center for Information Technology (FZI) price for his outstanding Ph.D. thesis on sensorimotor control in humanoid robotics and the development of the humanoid robot ARMAR. Since September 2010 he holds an Adjunct Professor position at the Georgia Institute of Technology (Georgia Tech), College of Computing, Interactive Computing.
