A Novel and Efficient Design of Parallel SCARA Robot
摘要
SCARA (Selective Compliance Assembly Robot Arm) which is a type of industry robot shows high speed, high flexibility, and high rigidity. It is demonstrated by performing any selective task repetitively with higher accuracy. Because it is advantageous for many types of assembly operations, these robots are highly efficient as industrial manipulators. This paper discusses the design characteristics of parallel SCARA mechanisms in detail. To reduce costs, we design the SCARA assembled as follows: (1) a microcontroller kit to govern the cost-effective selection of mechanical structures; (2) pneumatic systems; and (3) electrical driving components. The goal of this design is that it enables to recognition of the sorting-color and configuration-shape of objects in industrial settings utilizing computer vision. This SCARA including image-grabbers, robot feeders, and unloaders is easy to apply in an assemblage factory. Additionally, the user-friendly interface is optimized for efficient operation. The practical results show that it is effective with more than 95% of hundreds of samples.
