Which robot type utilizes 3 linear axes?

The gantry robot is characterized by its ability to operate along three linear axes, which allows it to move in three-dimensional space. This configuration is particularly effective for tasks that require a large working envelope and precise movement over long distances. The three linear axes typically allow for movements in the X, Y, and Z directions, making gantry robots suitable for applications like material handling, pick-and-place operations, and assembly lines.

Gantry robots are also often used in manufacturing settings where heavy loads need to be moved seamlessly across a defined area. The structure of a gantry robot usually consists of beams that span over the workspace, with a carriage that can traverse along these beams, providing reliable and repeatable operations.

Other robot types, such as vertically articulated, cylindrical, and SCARA robots, typically do not employ a three-linear-axis configuration. For example, vertically articulated robots often have rotational joints, which enable more complex movements but not purely along three linear axes. Understanding the distinct characteristics of various robots helps in choosing the right type for specific industrial applications.
