Abstract: A system and method for backdrivability control of end effectors in robotic systems are described. In one example, a robotic system includes a joint in a kinematic chain, an end effector at an end of the kinematic chain, and an assembly for backdrivability control of the joint. The assembly includes a frame comprising a flexure arm and a circular clearance area that extends around the joint, a brake band having one end secured along the circular clearance area and a second end secured at an end of the flexure arm, and a brake actuator configured to selectively pull the end of the flexure arm and tighten the brake band around the joint. The brake actuator can be actuated to tighten the brake band around the joint, arresting or dampening motion in the kinematic chain of the system for certain movements.

Abstract: Systems, devices, and methods are provided for an automated sleep assistant. An automated sleep assistant may comprise an audio input device for capturing sounds and utterances made by a user while sleeping. Audio data may be collected and analyzed to identify sleep patterns indicative of an adverse sleep-related condition such as Obstructive Sleep Apnea (OSA). A pillow comprising a plurality of regions with one or more sensors, one or more inflatable air bladders, and one or more haptic feedback devices may be utilized. A base unit device physically connected to the pillow may determine one or more external forces that mitigate the adverse sleep-related condition and cause the pillow to apply the one or more external forces to the user, for example, by using a pump to inflate an air bladder to help the user's head lift or tip to a specific angle that opens his or her airway.

Abstract: A mechanically intelligent end-of-arm tool includes a valve that is actuated by the action of the arm, such that a force applied to the object to be grasped opens the valve to expose a suction cup to the vacuum pressure. A spool valve, poppet valve, and butterfly valve, et al., can perform the valve function. The tool may include a button that has a rigid contact surface or may be deformable to provide a smoothing force to the object.

Abstract: Examples described herein are directed to an item manipulation system that includes an end of arm tool. The end of arm tool includes a suction manifold including multiple independently controllable asymmetrical suction zones. The end of arm tool is also configured to rotate about a tool axis to selectively align the independently controllable asymmetrical suction zones with target items for manipulation.

Abstract: An articulating end-of-arm tool includes back-drive capability. The tool has a cable drive including a vertically oriented capstan head, a pair of idler pulleys, a driven pulley and a tensioner. The driven pulley pivot on a hollow shaft, through which a vacuum channel passes. The vacuum channel extends through the length of the body, including past the vertically oriented motor. The driven pulley is within 10 degrees of perpendicular of the longitudinal axis of the tool.

Abstract: Examples described herein are directed to methods, computer-readable media, and systems for controlling an end of arm tool with one or more suction zones to pick up an item. Sensor data regarding the item is obtained. The sensor data is used to determine which of the one or more suction zones should be used to pick up the item. A rotational orientation is also determined that orients the determined suction zone(s) with the item. The end of arm tool is then instructed to create a suction force at the one or more suction zones and to pick up the item using the suction force.

Abstract: A system for backdrivability control of end effectors in robotic systems is described. In one example, a brake assembly for backdrivability control includes a frame having a clearance area. The brake assembly is positioned so that the rotor of the motor extends through the clearance area. The brake assembly includes a brake band secured at one distal end along the clearance area, extending around a periphery of the clearance area, and secured at a second distal end at a flexure arm of the frame. The brake assembly also includes a brake actuator including a permanent magnet at the distal end of the flexure arm and an electromagnet secured to the fame. The brake actuator can be energized to tighten the brake band around the rotor of the motor, arresting or dampening motion of the end effector for certain movements.
