2.2.2 Describe The Cylindrical Robot

 (Tips: Make sure you know how to draw both the robot configuration and work envelop!)

Figure: Cylindrical Configuration

•       consists of two orthogonal slides, placed ata 90° angle, mounted on a rotary axis 

•       Reach is accomplished as the arm of the robot moves in and out. 

•       For vertical movement, the carriage moves up and down on a stationary post, or the post can move up and down in the base of the robot. 

•       Movement along the three axes traces points on a cylinder

•       A cylindrical configuration generally results in a larger work envelope than a Cartesian configuration.

•       These robots are ideally suited for pick-and place operations. 

•       However, cylindrical configurations have some disadvantages.

–      Their overall mechanical rigidity is reduced because robots with a rotary axis must overcome the inertia of the object when rotating. 

–      Their repeatability and accuracy is also reduced in the direction of rotary movement.

–      The cylindrical configuration requires a more sophisticated control system than the Cartesian configuration.

•       Typical Applications for Cylindrical Configurations Include The Following:

•       Machine loading and unloading

•       Investment casting

•       Conveyor pallet transfers

•       Foundry and forging applications

•       General material handling and special payload handling and manipulation

•       Meat packing

•       Coating applications

•       Assembly

•       Injection molding

•       Die casting
