A gantry robot is a type of robot that moves around a work area on a structure called a gantry. This structure looks like a frame or crane, and it can move in different directions over the work area. Gantry robots are usually used to perform tasks such as loading and unloading materials, or to move parts assembly and welding. They usually have multiple arms that can lift and move objects in different directions. Gantry robots can be programmed to do the same tasks over and over again.
