Abstract: A robotic arm system includes first robotic arm, second robotic arm and main controller. The first robotic arm and the second robotic arm are configured to grab object. The main controller is configured to: determine whether first force vector of first force applied by the first robotic arm to the object is equal to second force vector of second force applied by the second robotic arm to the object; when the first force vector and the second force vector are not equal, obtain a first difference between the first force vector and the second force vector; and according to the first difference, change at least one of the first force applied by the first robotic arm to the object and the second force applied by the second robotic arm to the object so that the first force vector and the second force vector are equal.

Abstract: A signal line power receiving circuit includes a signal processing unit, a power unit, a signal interface, a first isolation unit and a first filter unit. The signal interface transmits and receives data signals and receives power signals all via a first signal line. The first isolation unit isolates the power signals in the first signal line. The first filter unit filters the data signals in the first signal line and supplies the power signals to the power unit. A signal line power supply circuit and a related signal line power supply system are also provided.
