Description: Wrist rotation in robotics refers to the ability of a robotic wrist to rotate around its axis, allowing for greater flexibility and precision in movement. This feature is fundamental for replicating human mobility, as the wrist is one of the most complex joints in the body, capable of performing movements in multiple directions. Wrist rotation is achieved through the use of motors and sensors that control the angle and speed of rotation, enabling the robotic wrist to perform tasks that require dexterity and coordination. This capability not only enhances the functionality of robots but also allows them to interact more effectively with their environment, manipulating objects with greater ease and accuracy. Wrist rotation is an essential component in the design of robotic arms, where the goal is to mimic the agility and versatility of human limbs, thus facilitating a wide range of applications in various fields such as industry, medicine, and research.
History: Wrist rotation in robotics began to develop in the 1950s with the first robotic arms, such as Unimate, created by George Devol and Joseph Engelberger. Over the decades, technology has evolved, incorporating more precise motors and advanced control systems. In the 1980s and 1990s, industrial robotics adopted these advancements, allowing robots to perform more complex tasks. In the 21st century, wrist rotation has become crucial in service robotics and medical applications, where delicate manipulation is required.
Uses: Wrist rotation is used in various applications, including industrial robotics, where robotic arms assemble products, and in robotic surgery, where precision in delicate movements is required. It is also applied in service robotics, such as domestic robots that manipulate objects and perform everyday tasks. Additionally, it is used in the research and development of advanced prosthetics that mimic human mobility.
Examples: An example of wrist rotation can be found in the KUKA LBR iiwa robot, which uses this capability to perform assembly tasks with high precision. Another example is the da Vinci robotic surgery system, which allows surgeons to perform complex procedures with precise robotic wrist movements. Additionally, robotic hand prosthetics, such as those from Open Bionics, incorporate wrist rotation to enhance the functionality and dexterity of the user.
