A robot includes a base; a robot arm that includes an arm which is rotatable around a rotation axis with respect to the base; and a connector that is provided in the base and is capable of being connected to an external wire. The connector is located on a side of the center of gravity more than a line that is perpendicular to a location of a center of gravity of the robot arm when the robot arm is in a basic posture and a line segment passing through the rotation axis and passes through the rotation axis, as viewed from an axial direction of the rotation axis.

A linear actuator has a base, a linear guide coupled to a flat, planar side of the base and extending in a travel length of an object to be moved, a contact plate extending along the flat, planar side of the base, and a carriage. The carriage includes an enclosure formed of an acoustically isolating material, a moving element configured to move along the guide and is coupled to the enclosure, a piezoelectric element including a contact site in physical contact with the contact plate, and a housing elastically holding the piezoelectric element, the housing coupled to the enclosure with no direct contact with the moving element. An electrical power source is in electrical communication with the piezoelectric element, wherein the power source energizes the piezoelectric element to effectuate movement of the carriage along the linear guide via the physical contact between the contact site and the contact plate.

A robot arm comprising a plurality of limbs articulated relative to each other, the robot arm extending from a base to a distal limb carrying a tool or an attachment point for a tool, the distal limb being attached by a revolute joint to a second limb, and the robot arm comprising a motor having a body and a drive shaft configured to drive rotation of the distal limb relative to the second limb about the revolute joint, wherein the body of the motor is fast with the distal limb.

A direct drive servo motor is provided and may include a quadrature encoder and a silicone rubber sleeve affixed to the encoder's shaft that is attached to the rotor hub and may also include an axle fixed to the rotor hub, inner and outer bearings, front and rear bearing plates, an outer stator, and an inner rotor rare earth magnet ring. A computer-controlled camera system is also provided and includes a direct drive camera gimbal; a pan-bar system; a robotic control system; a master interconnect unit; custom control software; and a track and gantry system. A universal camera tripod head adapter is also provided and includes front and rear clamps, a clamp handle, side and rear brackets and a silicone rubber sleeve affixed to the shaft of each encoder that rides on the pan and tilt axis lips of a camera tripod head.

A convertible panel includes a number of sub-panels which are movable between a first position in which the panels extend in the same plane to define a unified panel and a configuration in which one or more of the panels are moved into other planes which allow them to form steps. Multiple of the rotated panels may form a sequence of steps, e.g. a staircase. The convertible panel may be moved via a robotic mount, whereby the position or orientation of the convertible panel may be changed.

The present disclosure provides a robot servo jitter suppression method and device. The method includes: counting an amount of reciprocating jitter of an angular position of an output shaft of a robot servo in a predetermined period, after the robot servo enters a lock position state for a first predetermined period; determining whether the robot servo is in a jitter state according to the amount of the reciprocating jitter of the angular position of the output shaft of the robot servo and a predetermined fluctuation value; and suppressing the jitter of the robot servo by adjusting control parameter(s) of the robot servo, in response to the robot servo being in the jitter state. The robot servo jitter suppression method and device solve the problem of the jitter of the robot servo appears when the virtual positions of the robot servo and the robot joint structure are not properly controlled.

A material handling system includes storage rack configured to store one or more items. An Autonomous Mobile Unit (AMU) is configured to move within the storage rack to service the items. The storage rack includes at least one power rail to charge the AMU when within the storage rack. The AMU includes a wheel assembly with a cogwheel electrically connected to the power rail. The AMU includes a power supply electrically connected to the wheel assembly. The power supply includes a power converter electrically coupled to an Energy Storage System (ESS). The power rail includes a cog track with track teeth. The cogwheel includes cogwheel teeth intermeshed with the track teeth.

A robot arm and method for using the robot arm. Embodiments may be directed to an apparatus comprising: a robot arm; an end effector coupled at a distal end of the robot arm and configured to hold a surgical tool; a plurality of motors operable to move the robot arm; and an activation assembly operable to send a move signal allowing an operator to move the robot arm.

An assembly of a robot includes a first member, a second member rotatably connected to the first member to construct a robot joint structure, a driving assembly arranged within the first member, a speed reducer assembly to rotatably connect the first member to the second member, and a belt drive assembly connected to the driving assembly and the speed reducer assembly. The belt drive assembly is used to transmit rotary motion from the driving assembly to the speed reducer assembly, thereby rotating the first member with respect to the second member.
