Chapter 69 — Physical Human-Robot Interaction

An assistive, decision-and-control architecture for force-sensitive, hand-arm systems driven via human-machine interfaces (MM1)

The video shows the "grasp" and "release" skills demonstrated in a 1-D control task using the Braingate2 neural-interface system. The robot is controlled through a multipriority Cartesian impedance controller and its behavior is extended with collision detection and reflex reaction. Furthermore, virtual workspaces are added to ensure safety. On top of this, a decision-and-control architecture, which uses sensory information available from the robotic system to evaluate the current state of task execution, is employed.
