The Linkerbot Linker Hand J42 is the highest-dexterity configuration in the Linker Hand product family, offering up to 42 degrees of freedom in a six-finger industrial claw design driven by a tendon (cable) transmission architecture. Six fingers rather than five increases contact redundancy, enabling stable enveloping grasps on irregular objects and additional manipulation constraints—for example, stabilising an item with multiple fingers while another repositions it. The tendon-driven approach routes actuator cables through the hand structure to produce joint motion, keeping distal finger mass low, improving speed and inertia characteristics, and supporting compliance and shock tolerance during contact-rich interaction.

Communications across the Linker Hand family are delivered via CAN, RS485, and USB interfaces, with ROS compatibility for integration into manipulation research pipelines and robotic control stacks. The J42 is positioned for advanced flexible manufacturing, humanoid robot development, and research into fine in-hand manipulation—tasks such as picking and reorienting irregular items, handling soft packaging, operating human-designed tools, and bimanual assembly on mobile platforms. As a high-DoF industrial end-effector, specific sensor configurations, control electronics, and interface options are confirmed at system-design or quotation time.
