Learning the Affordances of Tools Using a Behavior-Grounded Approach (2009)

Alexander Stoytchev

Abstract. This paper introduces a behavior-grounded approach to representing and learning the affordances of tools by a robot. The affordance representation is learned during a behavioral babbling...

Toward Video-Guided Robot Behaviors (2008)

Alexander Stoytchev

This paper shows how a robot can detect its self-image in a TV monitor and use the realtime video to guide its own actions in order to reach an object that can only be observed through the TV image....

Abstract Combining Deliberation, Reactivity, and Motivation in the Context of a Behavior-Based Robot Architecture (2008)

Alexander Stoytchev

www.cc.gatech.edu/~saho/ This paper describes a hybrid mobile robot architecture that addresses three main challenges for robots living in human-inhabited environments: how to operate in dynamic and...

Robot Tool Behavior: A Developmental Approach to Autonomous Tool Use (2007)

Stoytchev, Alexander

The ability to use tools is one of the hallmarks of intelligence. Tool use is fundamental to human life and has been for at least the last two million years. We use tools to extend our reach, to...

Behavior-Grounded Representation of Tool Affordances (2005)

Stoytchev, Alexander

This paper introduces a novel approach to representing and learning tool affordances by a robot. The tool representation described here uses a behavior-based approach to ground the tool affordances...

Computational Model for an Extendable Robot Body Schema (2003)

Stoytchev, Alexander

The body schema is a perceptually derived model of the body which the brain uses to register the location of sensations on the body and to control body movements. This model of the body is not static...

Robot Behavioral Selection Using Q-learning (2001)

Martinson, Eric, Stoytchev, Alexander, Arkin, Ronald C.

Q-learning has often been used to learn primitive behaviors, or to coordinate a limited set of motor skills. However, the complexity of the algorithm increases exponentially with the number of states...
