HUMAN-ROBOT INTERFACE SYSTEM WITH BIDIRECTIONAL HAPTIC FEEDBACK
This abstract first appeared for US patent application 19004290 titled 'HUMAN-ROBOT INTERFACE SYSTEM WITH BIDIRECTIONAL HAPTIC FEEDBACK
Original Abstract Submitted
A bidirectional haptic feedback system, including: a flexible membrane configured to be mounted on a handheld controller; sensor-actuator units arranged on the flexible membrane, the sensor-actuator units respectively including a damping mechanism configured to mechanically isolate vibrations between adjacent sensor-actuator units; a control system configured to: generate vibration signals within selected frequency bands within a proximity to a natural resonant frequency range of the sensor-actuator units to drive the actuators of the sensor-actuator units to deliver haptic feedback to a user based on a state of the robot; simultaneously detect user grasp contact and pressure through analysis of back electromotive force (EMF) signals generated by the sensor-actuator units; and adjust robot control parameters dynamically in response to the detected grasp contact and pressure.
