LEAP Hand V2

LEAP Hand V2 is a low-cost, 8-DOF anthropomorphic robotic hand developed at Carnegie Mellon University for robot learning research. It features a hybrid rigid-soft structure with 3D-printed soft exterior skin over a robust internal bone structure, a foldable palm with two powered articulations (one for four fingers, one near thumb), and a highly dexterous MCP joint for human-like flexibility and grasping. Priced at $200, it assembles in under 2 hours and supports teleoperation, imitation learning, and sim2real tasks, outperforming pricier competitors.
