Grounding Perception: A Developmental Approach to Sensorimotor Contingencies

Sensorimotor contingency theory offers a promising account of the nature of perception, a topic rarely addressed in the robotics community. We propose a developmental framework to address the problem of the autonomous acquisition of sensorimotor contingencies by a naive robot. While exploring the world, the robot internally encodes contingencies as predictive models that capture the structure they imply in its sensorimotor experience. Three preliminary applications are presented to illustrate our approach to the acquisition of perceptive abilities: discovering the environment, discovering objects, and discovering a visual field.

Events! (Reactivity in urbiscript)

Urbi SDK is a software platform for the development of portable robotic applications. It features the Urbi UObject C++ middleware, to manage hardware drivers and/or possibly remote software components, and urbiscript, a domain specific programming language to orchestrate them. Reactivity is a key feature of Urbi SDK, embodied in events in urbiscript. This paper presents the support for events in urbiscript.
