What is a dexterous robot hand?
A dexterous robot hand is a multi-fingered end effector, often with 10–20+ degrees of freedom and touch sensors, that can grasp and manipulate varied objects like a human hand.

Definition
A dexterous hand is a robotic hand with several articulated fingers designed for human-like manipulation. Recent examples include Sharpa's 21-DoF W02, DH-Robotics' 13-DoF ADH-5-13 and PSYONIC's 30-sensor Ability Hand.
Design trade-offs
- DoF vs. size and weight
- Direct drive vs. tendons/linkages (backdrivability and repair)
- Sensing coverage (fingertips only vs. full-hand skin). See tactile sensing.
Why it matters
Hands are widely seen as the hardest part of general-purpose robots and a key to humanoids doing useful work.
Frequently asked questions
What does degrees of freedom (DoF) mean for a hand?
The number of independently controllable joints. More DoF allows more grasps but adds weight, cost and control complexity.
Why not just use a two-finger gripper?
Grippers are cheap and reliable for simple picks. Dexterous hands are needed for tools, in-hand manipulation and varied objects.
Why does touch sensing matter?
Cameras can't see contact forces or hidden surfaces. Tactile sensors let a hand adjust grip, avoid crushing and detect slips.
