Shadow Dexterous Hand Extra Lite

The Shadow Dexterous Hand is the only robotic hand on the market with 24 degrees of motion and 20 degrees of freedom (DOF), providing enhanced flexibility for grasping and manipulating various objects. Each finger can move independently, leading to unparalleled dexterity. The hand features a total of 129 sensors, enhancing precision and accuracy. It has long been a popular research tool for universities and companies and has recently found applications in artificial intelligence and machine learning (winner of the AIconics Award for Best AI Hardware Innovation in 2019). It is a key component of teleoperation solutions aimed at replacing human operators in dangerous situations, such as nuclear reactor decommissioning and bomb disposal. The revolutionary capabilities of the Shadow Hand earned Shadow Robot the prestigious Queen's Award for Enterprise for Best Innovation in 2019.

The Shadow Dexterous Hand is a standalone system with all controls and sensors integrated in the hand and forearm.

The Shadow Dexterous Hand Development Kit includes:

• Control systems
• Software (provided as needed under GNU GPL or BSD license)
• ROS compatibility
• PC
• Power supply
• Tactile sensors
• Additional devices (if required)
• Documentation and training

Features

• HUMAN KINEMATICS: Emulating human hand kinematics was a top priority in the development of the Dexterous Hand. With 20 active degrees of freedom and an additional 4 passive movements, it has a total of 24 joints. Each joint has a range of motion similar to that of a human hand, including the thumb and even flexion of the palm for the little finger.
• HUMAN SIZE: The Shadow Dexterous Hand is a marvel of miniaturization. Within the size of a human hand, it houses highly sensitive fingertips, absolute position sensors for each joint, and a control board on the palm allowing system expansion through additional devices. This significantly enhances its versatility, for example, by wearing standard gloves for protection during specific tasks.
• HIGH SENSOR BANDWIDTH: With a total of 129 sensors, the hand provides detailed telemetry data that can be used for developing innovative manipulation control systems or gaining a detailed understanding of the environment. In addition to absolute position sensing for each joint, the hand also includes force measurement for each actuator, tactile sensing of fingertips, temperature measurement, and motor current and voltage measurement. All this data is available to the user through a high-speed EtherCAT interface, ranging from 100 Hz to 1 kHz. This high data frequency is supported by the rapid movement of the hand, which can transition from open to closed in 0.5 seconds.
• OPEN PLATFORM: The hand is fully integrated into ROS, and documentation is available. Users can download a virtual model of the hand in ROS and use it immediately. The hand control, including position control algorithms, can be customized by the user in ROS. The hand's firmware itself can be provided for customizations.
