A cylindrical robot has at least one rotary joint at the base and at least one prismatic joint to connect the links. Along the joint axis, the rotary joint uses a rotational motion; along the prismatic joint, it moves in a linear motion. Their movements occur within a cylindrical-shaped work envelope. Cylindrical robots are used for assembly operations, handling of machine tools and die-cast machines, and spot welding.
