ZNJ Leap Hand Low-Cost Anthropomorphic Hand Dexterous Robotic Hand XL330 DIY Kit (Right Hand)

Description:
Dexterous manipulation has been a long-standing challenge in robotics. While machine learning techniques have shown some promise, results have largely been currently limited to simulation. This can be mostly attributed to the lack of suitable hardware. In this paper, we present LEAP Hand, a low-cost dexterous and anthropomorphic hand for machine learning research. In contrast to previous hands, LEAP Hand has a novel kinematic structure that allows maximal dexterity regardless of finger pose. LEAP Hand is low-cost and can be assembled in 4 hours from readily available parts. It is capable of consistently exerting large torques over long durations of time. We show that LEAP Hand can be used to perform several manipulation tasks in the real world—from visual teleoperation to learning from passive video data and sim2real.

Features:
* Kinematics and Dexterity: LEAP hand demonstrates side to side dexterity in both the finger up and finger down configuration. This is thanks to its universal abduction-adduction mechanism. LEAP Hand improves the opposition of the thumb and fingers, which means it can grasp objects more easily.
* Low Cost: LEAP Hand is low-cost and can be assembled in a few hours using a 3D printer, off-the-shelf parts, and common hand tools.
* Strength: LEAP Hand is one of the strongest robotic hands available today.
* Robustness: LEAP Hand can accurately complete repeated motions without overheating 
Human-like Versatility: LEAP Hand can grasp a wide variety of objects easily.
* Learning from Humans: LEAP Hand can learn to use joint-to-joint mappings or energy functions from human videos.
* Sim2Real Control: The URDF of LEAP Hand is highly accurate for all robotic hands and can be used in many RL frameworks.
