LINKERBOT Linker Hand O7 Robot Hand | 7 DoF, Worm Gear, CAN/RS485, 60N Grip, <±0.2mm Repeatability, 24V

Overview

LINKERBOT Linker Hand O7 is a dexterous Robot Hand featuring 7 degrees of freedom and 17 joints (7 active + 10 passive). It uses a worm gear transmission with CAN/RS485 control, delivering repeatable positioning of < ±0.2mm, a 60N maximum five-finger grip force, and 14N fingertip force per finger. Operating voltage is DC24V±10%, static current 0.2A, average no-load current 0.7A, and maximum current 2.6A. The hand weighs 634.5g, completes opening/closing in 1.25s, and lists a maximum load of 25kg.

Details

Linker Hand O7 offers 7 DOF, supports various robotic arms, data methods, simulators, interfaces. Compatible with ROS1/2, Python, C++. Features linkage-driven transmission and custom motor drivers for cost-effective, versatile manipulation.

LINKERBOT Linker Hand O7 offers compact agility, multi-sensor perception with cameras and e-skin, and end-cloud integration for code-free deployment. Enables precise manipulation, environmental awareness, and simplified customization across applications.

The LINKERBOT Linker Hand O7 Robot Hand measures 88 mm in palm width, 219.5 mm in total length, and 43.5 mm in thumb height. It provides 7 degrees of freedom across 17 joints—7 active and 10 passive. Its finger layout includes little, ring, middle, and index fingers, each with three segments, while the thumb has five segments. Joint diagrams detail motion ranges to enable precise robotic manipulation.

Thumb joints range 27.9°–69° at 27.09–62.5°/s; finger joints span 34.7°–102.7° at 28.92–85.58°/s, defining the product’s maximum motion angles and speeds.

Linker Hand O7B has pressure-sensitive sensors (6×12 array, 20N range, 100k cycles). Optional capacitive sensors provide 50Hz+ sampling, 0–30N range, 0.25N resolution, and 1cm detection for metals or human body.

Linker Hand O7B has 7 DoF, 17 joints, worm gear transmission, CAN/RS485 control. Weighs 634.5g, handles 25kg max load, operates at DC24V. Grip force up to 60N, positioning accuracy ±0.2mm.
