The PRASYS team – Perception, Robotics and Autonomous Systems
The research work of this Lab-STICC team (UMR CNRS 6285) focuses on the development of algorithms for mobile autonomous robots used to perceive the physical environment.
Such systems are based on three pillars: perception, action and the interaction between the two. Any autonomous perception system must be able to simultaneously analyze the data collected in relation to its immediate environment, become familiar with this environment and, depending on what this environment is, autonomously organize the steering and navigational aspects of its mission. This recent issue stems from the field of robotics in which the robot-environment interaction occurs via the sensor, which requires a study of the action-perception mechanisms.
Two main areas of focus have thus been defined: perception and action. Interaction between these two areas of focus is then essential for the system to be autonomous.
- Research focus 1: Autonomous action
- Research focus 2: Autonomous perception
Perception (research focus 2) is the process by which the system attempts to understand its observations and devise a relevant representation, not only of the environment’s current state, but also of its uncertainty. Using the perception’s results, the system must then reason out the actions (research focus 1) it must implement to achieve its mission goals, according to certain criteria such as efficiency, safety, speed, and energy consumption.
