Brain-Swarm Interaction and Control Interfaces


Abstract: This project focuses on understanding how multi-agent robotic systems can be controlled and coordinated by one human supervisor. More specifically, we focus on understanding how human supervisors perceive and plan high-level functions for a swarm of semi-autonomous agents. We define basic principles of communication and utilize them in building the language of supervised autonomy between the human operator and the multi-agent system. The overarching goal of the research is to unveil brain mechanisms that perceive multi-agent systems information, and model them in order to define methods for extracting centralized and/or de-centralized control commands for a multi-agent system.


Results: We have identified specific brain areas and patterns of activations related to collective behaviors of swarms of robots. Swarm cohesions seems to be represented in the brain of human supervisors (see paper 1 below). We have built a system that transforms ElectroEncephaloGraphic activity of the human brain to collective behaviors of robotic swarms. The system can output continuous variables for the control of the robots. Moreover, the system is combined with a joystick controller, to allow for a hybrid brain-machine interface between the humans and a robotic swarm. The system has been demonstrated via real-time control of a swarm of quadrotors using brain activity and joystick control.
