LINKERBOT Linker Hand O7 17‑DOF Bionic Robotic is part of the Linker Hand dexterous robotic hand series for robotic manipulation, education, research, industrial automation, and humanoid end-effector integration. Linker Hand O7 is positioned in the selection guide as an entry-level research and teaching dexterous hand, balancing cost, joint count, and practical grasping capability for robotics labs and education platforms. This listing is organized as a multi-variant product so the hand side, communication interface, and other available options can be selected from one product page. Features 17-DOF research-friendly platform - The selection guide lists 7 active + 10 passive joints for O7, making it a capable step up from simple grippers. Practical entry point - Designed for teams that want more dexterous function while keeping the platform accessible for introductory research. Linkage-drive architecture - The guide positions O7 as a linkage-drive hand for education, assisted grasping, and basic intelligent interaction validation. Left/right hand variants - Selectable left and right versions support single-hand, humanoid, and bimanual experiment layouts. CAN/RS485 integration - This listing provides selectable communication interface variants for matching the controller bus.
