An actuator unit (1) includes a direct drive motor (2), a first magnetic gear (3) connected to a rotating shaft (6) of the direct drive motor (2), a second magnetic gear (4) configured to be magnetically engaged with the first magnetic gear (3), and a planetary reducer (5) connected to a rotating shaft of the second magnetic gear (4).

Provided is a robot control device capable of easily setting a robot operation speed which is safe for an operator. The robot control device is equipped with: a selection unit for selecting a location of a human body; an allowed speed storage unit for associating and storing the location of the human body and the allowed speed for the robot at said location; and a robot control unit for retrieving the allowed speed associated with the location selected by the selection unit from the allowed speed storage unit, and setting the smallest value for the retrieved allowed speed as the maximum speed for the robot.

The present disclosure relates to protecting fragile members of robots from damage during fall events. In response to detecting a fall event, a fragile member of a robot can be actuated to a defensive configuration to avoid or reduce damage. An actuatable protective member can be actuated to protect a fragile member to avoid or reduce damage to the fragile member. Actuatable protective members can be dedicated protective members, or can be other members of the robot which serve different functionality outside of a fall event but act as a protective member during a fall event.

A teach pendant can be communicatively coupled to a light. The teach pendant can be communicatively coupled to a robot. The teach pendant can include one or more processors. The teach pendant can be configured to control the light. For instance, the teach pendant can be configured to selectively activate and deactivate the light. The light can be operatively connected to the teach pendant or the robot. The light can help robot programmers or technicians see in dark or dimly lit work environments. The light can improve user safety in such environments and/or enhance the work environment.

A surgical robotic arm includes a first link and a second link, wherein at least one of the first link or second link is movable relative to each other. The surgical robotic arm also includes a sensor assembly coupled to at least one of the first link or the second link. The sensor assembly includes a force sensing resistor assembly configured to measure force and an interface member disposed over the force sensing resistor assembly, the interface member configured to engage the at least one force sensing resistor assembly due to the interface member contacting an obstruction.

A robot control system includes a control device for controlling a robot and a portable operating panel connected to the control device. The portable operating panel and at least one other device include contact points connected in series. The control device includes a reception circuit that can detect the opening of at least one of the contact points. The portable operating panel includes a smart device having a sensor. The contact point included in the portable operating panel is opened and closed in conjunction with a physical movement of a switch member attached to an exterior of the smart device. The sensor can detect a physical quantity that changes in conjunction with the physical movement of the switch member. The portable operating panel transmits, to the control device, a detection signal indicating the physical quantity detected by the sensor or information about the physical quantity.
