Research

This project pursues three complementary research lines on design of 4-hands system, robot control and study of human motor control.

These are:

  • Design of 4-hands system: Development of robotic  feet interfaces and robot controllers to tele-operate the two extra robotic arms via haptic interfaces.
  • Shared Control: Robot Control Strategies to endow the robotic system with task autonomy, while the human supervises the interaction of the manipulation in both motion and force.
  • Human Motor Control: Study of underlying mechanisms of coordination among hands and feet in such supernumerary scenario. This with the goal of understanding human limits and develop training strategies using robotic technologies.

Autonomous force and motion generation 

Human Motor Control

Study of coordinated and uncoordinated control of the two feet
Example of Foot Position Control for Reaching one fixed target. In this illustration, when a target appears, the operator has a delay in reaction after which he/she modifies the position (from the previous aim), he/she reaches the target with an overshoot mistakes. Then, the operator carefully tries to correct the error before timeout, ending up on a static error. The relevant features are extracted for analysis: reaction time, overshoot error, mean velocity, etc.
