A robot includes a base, a first arm coupled rotatably around a first rotation axis relative to the base, a second arm having a base and rotating around a second rotation axis parallel to the first rotation axis relative to the first arm, a shaft placed at an opposite side to the first arm of the second arm, a drive unit rotationally driving the second arm around the second rotation axis, and a supporting portion supporting the shaft to rotate around a third rotation axis parallel to the second rotation axis and move the shaft along an axial direction of the third rotation axis, wherein the base has a first placement portion in which the drive unit is placed, a second placement portion in which the supporting portion is placed, a first beam and a second beam placed over between the first placement portion and the second placement portion.

A fiber includes M primary cores and N redundant cores, where M an integer is greater than two and N is an integer greater than one. Interferometric circuitry detects interferometric pattern data associated with the M primary cores and the N redundant cores when the optical fiber is placed into a sensing position. Data processing circuitry calculates a primary core fiber bend value for the M primary cores and a redundant core fiber bend value for the N redundant cores based on a predetermined geometry of the M primary cores and the N redundant cores in the fiber and detected interferometric pattern data associated with the M primary cores and the N redundant cores. The primary core fiber bend value and the redundant core fiber bend value are compared in a comparison. The detected data for the M primary cores is determined reliable or unreliable based on the comparison. A signal is generated in response to an unreliable determination.

A robotic system includes a robot arm including a first end and a second end opposing the first end, an optical cable extending between the first end and the second end of the robot arm, a lamp assembly disposed at the second end of the robot arm, the lamp assembly including a lamp holder having a plurality of ultraviolet (UV) lamps configured to cure paint, and a control module. The control module is configured to actuate the lamp holder and position one or more selected UV lamps of the plurality of UV lamps in communication with an end of the optical cable, and turn on the one or more selected UV lamps to transmit UV light through the optical cable to cure paint on a panel of a vehicle. Other examples charging robotic systems and methods are also disclosed.

A robotic arm body includes a structural part including a body portion made of plastic material and including an inner chamber; at least one mounting interface provided on the body portion and configured to be connected to a second component of a robot; an opening provided in the body portion and communicating with the inner chamber; and a reinforcement part fixed to the body portion at the opening.

A robot according to the present embodiment comprises: a body including an accommodation body in which an accommodation space is formed; a door connected to the body by means of a hinge, and rotated around the first hinge so as to open/close the accommodation space; a driving source provided in the body; a power transmission member for transmitting the rotation power of the driving force between the driving source and the door; and a spring, which has one side connected to the body and has the other side connected to the door so as to compensate for the gravity of the door.
