The Dexterous Hands are highly advanced, human-like robotic hands with finely controllable finger joints, designed for demanding gripping and manipulation tasks. Each hand features an innovative structure with multiple miniature servo actuators and integrated force/pressure sensors. Together, these components enable precise, differentiated gripping movements that closely resemble natural human grasping.
With multiple degrees of freedom and motorized joints per hand, the Dexterous Hands can perform a wide range of grasp types – from precision grips such as pinch and tripod grips to powerful, stable holding grips. Through a combination of force and position control, objects of various shapes and properties can be securely and adaptively picked up, held, and moved.
The robotic hands are designed for easy integration into modern robotic systems. They support common control frameworks and provide interfaces for programmable control, making them particularly suitable for robotics research, manipulation research, and humanoid systems.
Depending on the selected model, the behavior of the hands varies: Some variants are designed for high gripping force and robust handling, while others focus on fast and expressive movements or fine motor tasks.
