The method and a device are for protecting persons and stationary or autonomously moving obstacles in front of stationary or autonomously moving handling apparatuses such as manufacturing, transport, inspection or service robots and their manipulators from collisions within their workspace by pressure sensors in protective covers filled with medium in such a manner that the medium is not supplied to each individual protective element from outside, but the protective elements in their interior, in addition to a pressure sensor, also comprise a pressure-increasing device, which sucks in the medium, preferably ambient air, and generates a pressure in the interior of the protective element, which is adjustable from a control device.

A mobile cleaning robot can be movable about a flooring surface of an environment and can include a body, a pad tray, a cleaning pad, and a pad drive system. The body can at least partially define a reservoir configured to store liquid therein. The pad tray can be connected to the body and can be movable with respect to the body between a stored position and a deployed position. The valve can be connected to the body and can be movable between a closed position where liquid flow is limited and an open position where liquid flow to the cleaning pad is permitted. The drive system can be movable such that the pad tray or the cleaning pad can engage the valve to move the valve to the open position when the drive system moves the pad tray and the cleaning pad to the deployed position.

The invention refers to a legged robot (1000) comprising a torso (1) with a cavity (10) enclosing at least one robot component (11) and at least one leg with at least one actuator (100) that comprises an explosion proof housing. An absolute pressure (P.sub.c) within the cavity (10) is higher than an ambient pressure (P.sub.a), and wherein the explosion proof housing of the actuator (100) comprises at least one flame proof gap (105).

An end effector for a torpedo car capping robot and a capping method thereof. which effector and method belong to the field of robot control. The end effector at least comprises: a pickup and release unit, a buffer unit, a heat preservation cover distance measurement unit, an end effector structure protection unit and a pneumatic execution unit. The capping method comprises: by means of a heat preservation cover visual system, identifying the center of a heat preservation cover at the current position to be subjected to picking up, feeding back the center to a robot system, and a pickup center position of an end effector moving to the position right above the center of the heat preservation cover; by means of a numerical value which is fed back by a heat preservation cover distance measurement unit, driving the robot system to descend with the end effector and pick up the heat preservation cover; and a tank opening visual system identifying the current direction of a tank opening of a torpedo car, feeding back data to the robot system, guiding the robot system to move to the position above the tank opening, and releasing the heat preservation cover, so as to complete a capping operation. A robot is automatically guided to perform accurate capping operation on a tank opening of a torpedo car, thereby ensuring the safety of an operation device and an operated object during the whole operation process.

A robotic refuelling system and method for automatically operating a fuel station for refuelling vehicles includes a first detection unit for identifying the vehicle, a collaborative robot arm, and an adapter tool connected to the collaborative robot arm. The system is configured for detecting and identifying the vehicle, and controlling the collaborative robot arm and the adapter tool to engage at least one fuel dispenser unit of the fuel station and refuel the vehicle.

Disclosed is a substrate transfer apparatus disposed in a transfer chamber, the substrate transfer apparatus including: a robot main body having hands supporting a substrate; and a driving unit for moving the robot main body in a straight direction, wherein the driving unit includes: a driving case having an inner space; an actuator provided within the driving case, and connected to the robot main body; a cable veyor provided on one side of the actuator to guide the cable connected to the robot main body; an exhaust fan for exhausting atmosphere of the inner space; and an intake manifold for receiving suction force of the exhaust fan through a first intake path connected to the exhaust fan to intake a space where the cable veyor is located.

A collaborative robot arm for being used in an explosive environment includes electronics contained in at least one housing with at least one opening and a pressurization system configured for pressurizing the at least one housing with a gas at a predefined pressure level above atmospheric pressure.
