A system for non-destructive evaluation of an object uses a spherical coordinate system to control two robotic arms. In some examples, the system includes a radiation source coupled to one robotic arm, a radiation detector coupled to the other robotic arm; and a control unit configured to determine, based on input, a first position located on a first surface of a first sphere within the spherical coordinate system; determine, based on the input, a second position located on a second surface of a second sphere within the spherical coordinate system, wherein the second position is located opposite a midpoint of the spherical coordinate system from the first position; and control a motion of the source robotic arm and the detector robotic arm such that the radiation source and the radiation detector move to different ones of the first position and the second position.

A boom working device has a boom, mounted on and extending from a boom support, on which an end effector mounting interface is formed. The boom is equipped with two linear output structures, each in engagement with one of two drive wheels of the boom support. With respect to the boom support, the boom is both pivotable around a main axis and also capable of linear movement at right-angles to the main axis. Through harmonised rotary actuation of the drive wheels an operating movement of the boom may be generated, consisting either of a pivoting movement alone or of a linear movement alone or of the pivoting movement with simultaneously superimposed linear movement.

Disclosed are a master-slave mapping method for parallel platform, and a robotic arm system and a storage medium. The method comprises: acquiring a first transformation relationship between a user coordinate system and a calculation coordinate system; mapping displacement amounts of an end of a master manipulator in a master user coordinate system to an end of the movable platform according to a set proportional coefficient, to obtain a first target position of the end of the movable platform; determining a second target position of the end of the movable platform according to the first transformation relationship and the first target position; obtaining a movement amount of each of the telescopic rods of the parallel platform according to the second target position, and controlling a motion of the parallel platform according to the movement amount of each of the telescopic rods. The control of the robotic arm is simplified.

Devices, systems, and methods for autonomously sorting dirty laundry articles into batched loads for washing are described. For example, an autonomous sorting system includes an enclosed channel including a stationary floor extending between an inlet end and an outlet end of the channel, a plurality of arms disposed in series along the enclosed channel for selectively grasping at least one of the plurality of deformable articles in sequence. The system includes an outlet orifice adjacent the outlet end through which each separated deformable article exits the enclosed channel upon release by the terminal gripper of the one of the plurality of arms, and one or more conveyors disposed adjacent the outlet end configured for receiving thereon a plurality of bins for collecting for washing together two or more articles of the plurality of deformable articles released through the outlet orifice having a common sensor-detected one or more characteristics.

A medical arm system includes an operation apparatus operated by an operator and an arm apparatus remotely operated in response to an operation of the operator with respect to the operation apparatus, the arm apparatus has a base, a first unit connected to the base, a second unit connected to the first unit, a gimbal connected to the base and supporting the second unit, and an end effector unit connected to the second unit and provided with an operation tool to contact a patient. The first unit moves the second unit in a direction of at least one axis with respect to the base, and the second unit is interlocked with the first unit in a state supported by the gimbal and moves the end effector unit in the direction of the at least one axis.

The present invention relates to robots and discloses a seven-degrees-of-freedom humanoid robotic arm, including an upper arm component and a forearm component. One end of the upper arm component is provided with a shoulder pitching joint, a shoulder yawing joint and a shoulder rolling joint for connecting with a shoulder. One end of the forearm component is provided with an elbow pitching joint and an elbow rolling joint for connecting with the upper arm component, and the other end of the forearm component is provided with a wrist pitching joint and a wrist yawing joint for connecting with a robotic hand. The seven-degrees-of-freedom humanoid robotic arm of the present invention achieves a highly bionic design of a spherical joint of human shoulder, elbow and wrist joints.

Devices, systems, and methods for repositioning a deformable laundry article are described. For example, a robotic device includes a conveyor configured to transfer the deformable laundry article outside of a work volume, two or more lifters including grippers individually anchored about the perimeter of the work volume, two or more sensors disposed at fixed locations about the work volume, and a memory storing data indicative of repositioned deformable laundry articles. A controller is in operative communication with the memory, the two or more sensors, and the two or more lifters. The controller is configured to receive a signal from the sensors, identify grip points on the deformable laundry article suspended above the conveyor, instruct a lifter to grip and lift an identified grip point to the suspension height, determine whether the deformable laundry article is repositioned, and instruct the lifters to lower the repositioned deformable laundry article onto the conveyor.

A nuclear emergency multifunctional operation robot includes a base, a mechanical arm, a tool change-over device, and motion supporting devices. The base includes a pedestal, a mounting seat A, a mounting seat B, a mounting seat C, a rotation driving mechanism A, and a rotation driving mechanism B.
