A vacuum-based end effector for selectively engaging parcels includes a base plate to which a plurality of vacuum cups are mounted and configured to be placed in fluid communication with a vacuum source. Each vacuum cup includes a bellows having a distal end connected to a lip. The vacuum-based end effector further includes a linear actuator that is mounted to the base plate and includes an extendible arm to which at least one vacuum cup is operably connected. The linear actuator can be selectively actuated to extend the extendible arm and move the lip of the vacuum cup operably connected to the extendible arm below a common plane defined by the lips of vacuum cups which maintain a fixed position relative to the base plate to individually address a target parcel. The vacuum-based end effector can be combined with a robot to provide an improved system for selectively engaging parcels.

A robot control apparatus includes a drive controller configured to control a plurality of motors which are configured to drive a plurality of link mechanisms of a parallel link robot, respectively, and abnormality determination circuitry configured to determine based on state data of the plurality of motors whether at least one of collision of the parallel link robot and dislocation in the link mechanisms occurs.

A linear motion mechanism includes: a plurality of linear motion elements that are cascaded in a mutually movable manner; a shaft fixed to one of adjacent linear motion elements among the plurality of linear motion elements; and a slider movably engaged with the shaft and fixed to the other of adjacent linear motion elements.

The disclosure describes devices, systems and methods relating to a transfer chamber for an electronic device processing system. For example, a robot can include a first mover configured to be driven by a platform of a linear motor, a support structure disposed on the first mover, a first robot arm attached to the first end of the support structure at a shoulder axis, and a first arm drive assembly. The first drive assembly can include a first pulley attached to a first end of the support structure and to the first robot arm at the shoulder axis, a second pulley attached to a second end of the support structure, a first band connecting the first pulley to the second pulley, and a second mover configured to be driven by the platform of the linear motor, where the second mover is connected to the first band, and where motion of the second mover relative to the first mover causes the first band to a) rotate the first pulley and the second pulley and b) rotate the first robot arm around the shoulder axis. Also disclosed are systems and methods incorporating the robot.

A robotic trolley collection system and methods for automatically collecting baggage/luggage trolleys are provided. The system includes a differential-driven mobile base; a manipulator mounted on the differential-driven mobile base for forking a trolley, having a structure same as a head portion of the trolley; a sensory and measurement assembly for providing sensing and measurement dataflow; and a main processing case for processing the sensing and measurement dataflow provided by the sensory and measurement assembly and for controlling the differential-driven mobile base, the manipulator, and the sensory and measurement assembly. The method includes localizing and mapping the robotic trolley collection system; detecting an idle trolley to be collected and estimating pose of the idle trolley; visually servoing control of the robotic trolley collection system; and issuing motion control commands to the robotic trolley collection system for automatically collecting the idle trolley.

Simulated motion of the papillary muscles in a heart simulator is provided that simulates natural motion of the papillary muscles. This improves heart valve simulation. This can be done with a six degree of freedom robotic actuator (e.g., a Stewart platform or the like) appropriately driven by a controller. This can also be done with a robotic actuator that provides constrained motion of its effector by including a mechanical linkage, as long as the resulting simulated papillary muscle motion includes time-varying position and orientation of the papillary muscle.

An omnidirectional cart transport mechanism includes an automatic guided vehicle that includes a drive wheel and a drive mechanism that drives the drive wheel, and travels on a road surface by driving the drive wheel using the drive mechanism, a side guide mechanism that includes a pair of side plates movable in a first direction of approaching or separating from each other, and guides a cart to be coupled to the automatic guided vehicle to a coupled position by bringing the pair of side plates closer to each other with the cart positioned between the pair of side plates, and a cart lift mechanism that lifts a coupled portion of the cart guided to the coupled position.

An apparatus includes a spindle platform; a traversing platform configured to move in a first direction; a lift system connected to the spindle platform and the traversing platform, the lift system configured to move the spindle platform in a second direction perpendicular to the first direction; a movable arm connected to the spindle platform, the movable arm including a first link connected to the spindle platform, a second link connected to the first link, and a third link connected to the second link, and a first actuator connected to the spindle platform and configured to cause a rotation of the first link, and a second actuator in the movable arm and configured to cause a rotation of the second link. The first actuator extends from the spindle platform into the first link to occupy a combined thickness of the spindle platform and the first link.

A piezoelectric vibrator has a first frequency region where the phase difference between a pickup signal representing the vibration of the piezoelectric vibrator and a drive signal that drives the piezoelectric vibrator does not monotonously change in accordance with the frequency of the drive signal and a second frequency region where the phase difference monotonously changes in accordance with the frequency of the drive signal. A method for controlling a piezoelectric driving apparatus including the piezoelectric vibrator controls the frequency of the drive signal in such a way that pickup voltage representing the amplitude of the pickup signal is fixed in the first frequency region and controls the frequency of the drive signal in such a way the pickup voltage is fixed with the phase difference maintained smaller than or equal to a prespecified value in the second frequency region.
