The needs of cleaning operations can be satisfied.

A system for polishing a surface of a component includes a motorized apparatus including a body, a drive system coupled to the body, and an arm including a proximal end coupled to the body and a distal end opposite the proximal end. The motorized apparatus further includes a tool coupled to the distal end of the arm. The tool is configured to polish the surface of the component. The motorized apparatus also includes an actuator coupled to the arm. The system also includes a controller configured to position the tool relative to the component by positioning at least one of the body and the arm relative to the component to reach the target area on the component while maintaining a distance between the tool and the body that is less than a threshold distance. The threshold distance is less than a full reach of the arm and is determined to prevent vibrations of the tool and the arm from exceeding a predefined level.

Provided is a system controlling method that improves versatility of a surface treatment system. In the treatment system, for treating a surface of an object by a treatment machine while moving the treatment machine relative to the surface of the object by an action of a work robot, there is provided a trackless type work machine mounting the work robot on a self-propelled cart; and the work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction. A work area in which the object and the work machine are present is image-captured by a position determination camera. A control device recognizes relative positional relation between the object and the self-propelled cart based on image-captured data of the position determination camera and controls the self-propelled cart based on the recognized relative positional relation, whereby the work machine is moved to a designated work position near the object.

The invention concerns a sanding head for an abrasion arrangement, where the sanding head comprises an abrading drum with a centre axis and contact wheels at both ends of the abrading drum, where the contact wheels have the same or substantially the same centre axis as the abrading drum, and where the sanding head comprises a suspension swivel arrangement, and where the sanding head comprises at least one load sensor connected to at least one contact wheel. The invention also concerns an abrasion arrangement and a use of a sanding head. The object of the invention is to ensure an equal contact on the abrading drum as well as an equal contact over the entire length of the abrading drum, and where the invention can be used on plane, convex and/or concave surfaces.

An automated wire drawing system for a side wall of a railway vehicle and a process method using the system for wire drawing operation are provided. The automated wire drawing system comprises a central control system, a robot, a wire drawing device, a railway, a laser measurement system, an offline programming software and an electronic system, so that the wire drawing operation of the side wall of a vehicle body can be automatically finished. The process method can realize the automated flexible and intelligent wire drawing operation, the change of the surface shape of a work piece within a certain range can be automatically adopted, and a constant normal wire drawing force is always maintained, to achieve the optimal wire drawing effect.

A device for performing maintenance on an object is provided. The device for performing maintenance on an object comprises an attaching means that enables the device to attach to a part of an object, the attaching means being configured to deform in accordance with a shape of a part of the object, a moving means that enables the device to move on the object, and a maintenance means that performs maintenance on the object. In one embodiment of the present invention, the attaching means is configured so that the device maintains a state of attaching to the part of the object by the deformation of the attaching means even when a shape of a part of the object changes in association with the movement.

An automated hand tool sharpening and cleaning system for sharpening the two opposed cutting edges of domestic, industrial, sport, or hobby hand tool like a knife blade is provided by the invention. The apparatus comprises a six-axis robotic arm, a pneumatic gripper, a vision sensor camera for profiling the blade edges, a robotic controller, and sequentially-arranged grinding, coarse sharpening, fine sharpening, and buffing rotating wheel assemblies used to grind, sharpen, and buff or polish the cutting edges of the knife blade. The blade cutting edges are profiled by the camera image that is processed by associated software to define the blade by multiple points defined along its edge, followed by a set of algorithms that are used to clean up any discrepancies in the profile data. The resulting corrected profile data is then translated into a set of machine control commands fed to the robotic arm and pneumatic gripper via the robot controller for manipulating the knife blade edges via the robotic arm with respect to each of the grinding, coarse sharpening, fine sharpening, and buffing/polishing wheels and an associated wash station for remove bits of metal and other residue resulting from the sharpened knife blade.

A method for controlling polishing and grinding is provided, including: generating an initial polishing and grinding trajectory for robot movements based on a three-dimensional contour of a work piece; adjusting the initial polishing and grinding trajectory based on a first optimized adjustment value and generating an optimized polishing and grinding trajectory; and evaluating the polishing and grinding quality of the work piece and using the polishing and grinding quality to generate a second optimized adjustment value.

The present invention relates to a mobile blasting apparatus for injecting abrasives onto the surface of an article to be processed, the mobile blasting apparatus comprising: a body; a frame structure including a first rail extending along a first direction; a first moving device which can move the position of the body reciprocally along the first rail; and an injection device coupled to the body so as to inject the abrasives. According to the present invention, all processes can be automated without workers' manual work, so that the overall working time is reduced even when an article to be processed is large in length or volume, and there is no concern that work over a long time, strong jets of abrasives, and noxious dust would cause harm to worker health.
