Parallel manipulators are robotic systems that consist of multiple arms connected to a common platform. These arms work together to control the movement of the platform, allowing for precise positioning and stability. They are often used in applications like robotic surgery, 3D printing, and industrial automation due to their ability to handle heavy loads while maintaining accuracy. One of the key advantages of parallel manipulators is their high stiffness and strength compared to serial manipulators, which have a single arm. This design enables them to perform complex tasks with minimal error. Their unique structure also allows for greater flexibility in movement, making them suitable for various tasks in fields such as aerospace and automotive engineering.
