While machine learning techniques \r\nhave shown some promise, results have largely been currently limited to \r\nsimulation. This can be mostly attributed to the lack of suitable \r\nhardware. In this paper, we present LEAP Hand, a low-cost dexterous and \r\nanthropomorphic hand for machine learning research. In contrast to \r\nprevious hands, LEAP Hand has a novel kinematic structure that allows \r\nmaximal dexterity regardless of finger pose. LEAP Hand is low-cost and \r\ncan be assembled in 4 hours from readily available parts. It is capable \r\nof consistently exerting large torques over long durations of time. We \r\nshow that LEAP Hand can be used to perform several manipulation tasks in\r\n the real world—from visual teleoperation to learning from passive video\r\n data and sim2real.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e* Kinematics and \r\nDexterity: LEAP hand demonstrates side to side dexterity in both the \r\nfinger up and finger down configuration. This is thanks to its universal\r\n abduction-adduction mechanism. LEAP Hand improves the opposition of the\r\n thumb and fingers, which means it can grasp objects more easily.\u003cbr\u003e* \r\nLow Cost: LEAP Hand is low-cost and can be assembled in a few hours \r\nusing a 3D printer, off-the-shelf parts, and common hand tools.\u003cbr\u003e* Strength: LEAP Hand is one of the strongest robotic hands available today.\u003cbr\u003e* Robustness: LEAP Hand can accurately complete repeated motions without overheating \u003cbr\u003eHuman-like Versatility: LEAP Hand can grasp a wide variety of objects easily.\u003cbr\u003e* Learning from Humans: LEAP Hand can learn to use joint-to-joint mappings or energy functions from human videos.\u003cbr\u003e* Sim2Real Control: The URDF of LEAP Hand is highly accurate for all robotic hands and can be used in many RL frameworks.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOptional XL330-M288-T Servo (for XL330 Version):\u003c\/b\u003e\u003cbr\u003e* Model Name: XL330-M288-T\u003cbr\u003e* Microcontroller: CORTEX-M0+ (64 [MHz], 32Bit) for ARM\u003cbr\u003e* Position Sensor: Non-contact Absolute Encoder (12Bit, 360 [°])\u003cbr\u003e* Motor: Cored Motor\u003cbr\u003e* Baud Rate: 9,600 [bps] ~ 4 [Mbps]\u003cbr\u003e* Control Algorithm: PID control\u003cbr\u003e* Resolution: 4096 [pulse\/rev]\u003cbr\u003e* Reduction Ratio: 288.4:1\u003cbr\u003e* Stall Torque: 0.52 [N.m] (at 5.0 [V], 1.47 [A])\u003cbr\u003e* No-load Speed: 103 [rev\/min] (at 5.0 [V])\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOptional XC330-M288-T \u003c\/b\u003e\u003cb\u003eServo\u003c\/b\u003e\u003cb\u003e (for XC330 Version):\u003c\/b\u003e\u003cbr\u003e* Model Name: XC330-M288-T\u003cbr\u003e* Microcontroller: CORTEX-M0+ (64 [MHz], 32Bit) for ARM\u003cbr\u003e* Position Sensor: Non-contact Absolute Encoder (12Bit, 360 [°])\u003cbr\u003e* Motor: Coreless DC Motor\u003cbr\u003e* Baud Rate: 9,600 [bps] ~ 4 [Mbps]\u003cbr\u003e* Control Algorithm: PID control\u003cbr\u003e* Resolution: 4096 [pulse\/rev]\u003cbr\u003e* Reduction Ratio: 288.35:1\u003cbr\u003e* Stall Torque: 0.93 [N.m] (at 5.0 [V], 1.80 [A])\u003cbr\u003e* No-load Speed: 81 [rev\/min] (at 5.0 [V])\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePacking List:\u003c\/b\u003e\u003cbr\u003e* 1 x Set of Robotic Hand\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackaging Details:\u003c\/b\u003e\u003cbr\u003e* Package weight: 1kg\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAttention:\u003c\/b\u003e\u003cbr\u003e* This product is an open-source project.
