Compliant payload presentation using robotic system with coordinated serial and parallel robots
A robotic system for presenting a payload within a workspace includes a pair of serial robots configured to connect to the payload, a parallel robot coupled to a distal end of one of the serial robots such that the parallel robot is disposed between the distal end and the payload, a sensor situated within a kinematic chain extending between the distal end and the payload, and a robot control system (RCS). The sensor outputs a sensor signal indicative of a measured property of the payload. The RCS includes a coordinated motion controller configured to control the serial robots, and a corrective motion controller configured to control the parallel robot. Parallel robot control occurs in response to the sensor signal concurrently with control of the serial robots in order to thereby modify the property of the payload in real-time.
Tactile perception apparatus for robotic systems
A human-like tactile perception apparatus for providing enhanced tactile information (feedback data) from an end-effector/gripper to the control circuit of an arm-type robotic system. The apparatus's base structure is attached to the gripper's finger and includes a flat/planar support plate that presses a pressure sensor array against a target object during operable interactions. The pressure sensor array generates pressure sensor data that indicates portions of the array contacted by surface features of the target object. A sensor data processing circuit generates tactile information in response to the pressure sensor data, and then transmits the tactile information to the robotic system's control circuit. An optional mezzanine connector extends through an opening in the support plate to pass pressure sensor data to the processing circuit. An encapsulating layer covers the pressure sensor array and transmits pressure waves generated by slipping objects to enhance the tactile information.
Deformable sensors and methods for modifying run-time membrane stiffness
Deformable sensors and methods for modifying membrane stiffness are provided. A deformable sensor may include a membrane coupled to a housing to form a sensor cavity. The deformable sensor may further include a rotational element having an adjustable vertical position and a modifiable rotation. The rotational element may be supported at a base of the sensor cavity. The rotational element may be configured to establish and withdraw contact with respect to the membrane to modify stiffness of the membrane. The rotational element may further be configured to modify stiffness of the membrane by withdrawing the rotational element from the membrane.
