Embodiments of the present disclosure relate to a motor and an industrial robot. The motor comprises a main body, an inner end cover, an outer end cover, a first oil seal, a second oil seal and an oil leakage sensor. The main body comprises a rotor extending along an axial direction. The inner end cover is coupled to the main body and comprises a first hole for the rotor to pass through. The outer end cover is arranged outside the inner end cover along the axial direction and abuts against the inner end cover. The outer end cover comprises a second hole for the rotor to pass through, wherein a first oil seal is arranged adjacent to the second hole and a second oil seal is arranged inside the first oil seal and is adjacent to the second hole. A gap is provided between the first oil seal and the second oil seal along the axial direction. The oil leakage sensor is provided in a through hole penetrating the outer end cover along the axial direction and is configured to detect the amount of oil or grease flowing to the oil leakage sensor via the first oil seal. The motor according to the present disclosure is characterized in dual sealing and an automatic oil leakage detection, thereby improving the motor sealing reliability and the digitalization of the motor oil leakage detection.

There is disclosed a motor (100) comprising: a stator (120), comprising a core (122) and a plurality of windings (124); and a rotor (140), comprising a plurality of permanent magnets (150, 152, 154), wherein a first portion of the magnets (150, 152) is disposed on two axial rotor portions (142, 144) in close proximity to two respective axial sides of the windings (124), and a second portion of the magnets (154) is disposed on a radial rotor portion (146) in close proximity to a radial side of the windings (124), and wherein energising the windings (124) causes a torque to be applied to the rotor (140) via said two axial rotor portions (144, 144) and said radial rotor portion (146).

The invention relates to a delta robot (1) with at least two robot arms (2a, 2b, 2c), preferably three robot arms (2a, 2b, 2c), which can be moved relative to a robot base (3) via a respective motor (5a, 5b, 5c) arranged on the robot base (3) and associated with the respective robot arm (2a, 2b, 2c), wherein the motors (5a, 5b, 5c) each comprise part of a motor-controller-encoder unit (4a, 4b, 4c) with integrated servo-controller (6a, 6b, 6c) and encoder in order to increase the mechanical accuracy and efficiency of the delta robot (1).

A vertical articulated robot includes a plurality of joint axis portions configured to rotationally drive a plurality of arms. The plurality of joint axis portions include a narrow joint axis portion. In the narrow joint axis portion, at least one of at least a portion of a brake or an oil seal is arranged inside a recess.

A vibration wave motor includes a vibrator, a contact body to be brought into contact with the vibrator, a shaft fixed to the contact body, and a fixing member configured to fix the contact body and the shaft from the shaft side.

Provided is a robot gripper. The robot gripper comprises: at least two finger units which symmetrically face each other; finger tips which are provided at the terminal ends of the finger units and linked with the operation of the finger units; and a driving unit connected to the finger units so as to operate the finger units. When the finger units are operated, the finger tips pinch-grip an object by moving toward an inner area, which at least two of the finger units form by facing each other, while adapting to conflicts with constraints of the external environment. A force applied to the finger tips in order to enable the pinch grip can act in a direction that raises the object while being applied toward the inner area, or act in a direction lowering the object while being applied toward the inner area.

Disclosed herein are various robotic surgical devices and systems that include first and second elongate bodies, first and second driveshafts disposed through the second elongate body, and an in-line shoulder joint with a robotic arm coupled thereto. In certain implementations, the in-line shoulder joint has a differential yoke and a dual shaft disposed within the yoke lumen.
