Robot grabbers are essential components in robotic systems designed for tasks. They enable robots to pick, hold, and move objects in various industrial applications. The design and functionality of grabbers can vary significantly based on the intended application, the types of objects being handled, and the environment. Understanding the basic principles of different grabber types sets the foundation for exploring their practical uses and advantages.
A simple single arm grabber mechanism is a pinching grabber where only one arm moves, while the other remains stationary. This grabber typically consists of a fixed arm and a moving arm controlled by a motor or . Its advantages include a simpler design with fewer moving parts, requiring only one motor or servo. An example use of this grabber is picking up small blocks from a fixed position.
In contrast, a parallel grabber consists of two parallel that move symmetrically to grab objects, allowing for simultaneous contact along the length of the arms. This type of grabber is best suited for uniformly shaped objects such as boxes or crates. An example use of the parallel grabber is holding rectangular objects like or cans. Other types of grabbers include the suction grabber, which uses a vacuum or air pressure to attach to smooth, flat surfaces, and the magnetic grabber, which is effective for handling metallic objects due to its reliance on electromagnetism.
