What Are Parallel Robots?
Definition
A parallel robot, also known as a parallel manipulator, consists of several arms that connect a single platform to a fixed base. This structure differs from traditional robots, which often use a series of joints and links in a chain-like arrangement. Engineers design parallel kinematic robots to achieve high speed and precision in demanding environments. The term “parallel manipulator” refers to the same type of robot, emphasizing the multiple arms working together to control movement. These robots excel in tasks that require exact positioning and rapid motion, making them essential in industries such as manufacturing and electronics.
Parallel kinematic robots stand out because their arms move together, sharing the load and improving stability. This design allows for better control and accuracy compared to serial robots.
