Videos

Navigation in indoor environment

The video presents a surveillance task in our lab. It shows the navigation approach of OrbiOne robot (RB1-robotnik robot) in our apartment.

The robot navigates different apartment rooms in order to check user availability (living room and bedroom), visits (apartment front door after the doorbell rings) or alarm situation (fridge open-door alarm).

Quiz Game and Context Awareness

Trivia game between user and robot. The conversation is interrupted by a ringbell.

Research

Arhictecture

We have a three layer architecture based on ROS and BICA [1]. The lower layer corresponds to ROS, and is in charge of hardware management. The intermediate layer provides the robot skills in order to carry out specific duties (perception, navigation,...). The top layer presents BICA. It is a component-based for generating behaviors architecture. This node coordinates the various capabilities of the robot depending on the task to be carried out by the robot. Figure 2 shows the overall architecture of the software we have developed for participating in the RoCKIn competition.
