Cartesian robots, also known as linear robots or gantry robots, are used in the industrial space working on three linear axes using the Cartesian Coordinate System (x, y, z), meaning they move in straight lines on 3-axis, up and down, in and out and side to side. Compliance is achieved by using a single plane with two parallel joints. They are also referred to as rectilinear or gantry robots. The advantages and disadvantages of the SCARA method in relation to a typical compliance apparatus such as a RCC, may be seen from the following:2 RCC can correct both angular and lateral errors, and SCARA only lateral ones, RCC is a wrist compliance system and its design is specified by its weight and dimensions of gripped The speed of these robots is one of their disadvantages. But opting out of some of these cookies may have an effect on your browsing experience. Exposed guiding surfaces require covering in corrosive or dusty environments, and cartesians cannot operate under water, as scara's are able to do. Their main disadvantages include; complex They are also used to handle semiconductor wafers and to load and unload machines. SCARA Robots currently available can achieve tolerances lower than 10 microns. Cartesians have the most rigid robotic structure for a given length, since the axes are supported at both ends. This selective conformity ensures that although it is rigid along the Z-axis, it is flexible along the X-Y axes. Their application is also useful in: flight stimulators and automobile stimulators, as well as for optical fiber alignment. These robots are typically driven by servo motors and can be as essential as a two-axis configuration or as complex as ten or more axes. For this application, a modified robot bores holes in the femur with a router bit. There has been astonishing progress in the field of robotics, and the future is here.
