The Golem Group presents a generic model for solving service robot tasks. The model proposes an abstract solution for the managing of diverse kinds of behaviors in systems based on human-robot interaction. The model is implemented in Golem-II+, which coordinates its multimodal capabilities to perform communicative interactions independently of the domain and the concrete task. It also includes communicative strategies for error prevention and recovery.

1. TASK DESCRIPTION
Golem-II+ carries out different tasks with a
generic interactive model. The model is based on
interaction protocols named Dialogue Models
(DMs). The DMs describe sets of situations in
which the expectations, intentions and actions
related to a specific task are represented. In a
DM, each situation (S) is an informational state.
To move from Si to Sj the match between an
expectation (α) and an action (ß) has to be
accomplished.
The Interaction-Oriented Cognitive Architecture
(IOCA) integrates perception, thought and action
with computational structures and processes. It
offers a flexible framework to design complex
tasks. The DMs are integrated into a cognitive
architecture in order to coordinate the robot's
capabilities and its interaction with humans.

The Golem Group presents a generic model
for solving service robot tasks. The model
proposes an abstract solution for the
managing of diverse kinds of behaviors in
systems based on human-robot interaction.
The model is implemented in Golem-II+, which
coordinates its multimodal capabilities to
perform communicative interactions
independently of the domain and the concrete
task. It also includes communicative strategies
for error prevention and recovery.
Golem-II+ is able to:
* listen and interpret linguistic instructions
* explain the information requested by the
user about the domain
* navigate through its environment
* visual object recognition
* grasp objects
* recover from misinterpretations
The system interacts with the user in an
intentional level. The robot's actions are
causally related to the expressed intentions
during the communication process.
