Adaptive Interface Mapping for Intuitive Teleoperation of Multi-DOF Robots
The supervisory control of multi-DOF robots by humans is a demanding application. If a single operator is tasked with direct control of a humanoid robot, performing coordinated tasks becomes non-intuitive and corresponds to unsustainable mental loads even for the most skilled operators. In this paper we use reinforcement learning to adaptively change the interface mapping from the operator user interface to the robot in such a way as to reduce the associated operator mental load. Based on the results of the interaction with the robot, we change the dynamical map describing the relationship between user commands and robot actions. The contribution of this paper is the adaptation of the interface map using reinforcement learning with reward functions associated with quantitative performance metrics. We present promising experimental results showing that the use of the proposed scheme can result in an easier to use interface map for a multi-DOF assistive robot controlled via a brain activity sensor.
