Robotic gripper with integrated tactile sensor arrays
A robotic gripper (end effector) for an arm-type robotic system includes a hierarchical sensor architecture that utilizes a central data processing circuit to generate rich sensory tactile data in response to pressure, temperature, vibration and/or proximity sensor data generated by finger-mounted sensor groups in response to interactions between the robotic gripper and a target object during robotic system operations. The rich sensory tactile data is used to generate feedback signals that directly control finger actuators and/or tactile information that is supplied to the robotic system's control circuit. Sensor data processing circuits are configured to receive single-sensor data signals in parallel from the sensor groups, and to transmit corresponding finger-level sensor data signal on a serial bus/signal line to the central data processing circuit. Each sensor group and an associated sensor data processing circuit are disposed on a PCB structure and mounted on a contact portion of an associated gripper finger.
