The book "Underactuated Robotic Hands" provides a comprehensive summary of years of research in the field of intelligent manipulation and grasping techniques in robotics. The authors, who possess internationally recognized expertise, present innovative approaches to underactuation that are successful both theoretically and practically. Given the increasing application of robotics in unstructured environments, such as space, underwater, or in surgery, the importance of grasping and manipulation capabilities becomes evident. This work is not designed as a textbook but serves as a valuable reference for graduate students and professionals looking to engage with the latest developments in robotics.
