Parallel robots are also known as parallel linkage robots because they consist of parallel joint linkages connected to a common base. Since each joint on the end effector is directly controlled, the positioning of the end effector can be easily manipulated through its arm, enabling high-speed operations. Parallel robots have a dome-shaped workspace. They are usually used in applications such as rapid picking and placing or product transfer. Their main functions include grabbing, packaging, palletizing, and loading/blanking for machine tools, etc.
