The hand is a vital organ performing multiple tasks such as operations, inspections, adaptations, and explorations. The loss of a hand significantly impacts functionality and imposes a psychological burden on amputees. Despite numerous developments, only 30 to 50 of upper extremity amputees use their prostheses. To increase acceptance and overcome the limitations of current prostheses, this research proposes a biomechatronic-based prosthetic hand design that closely mimics the human hand in terms of cosmetics, grasping ability, and controllability. The design anatomically reproduces the bone connection structure and ligaments in the human hand, resulting in a lightweight and user-friendly prosthetic hand.
