The ORCA v1 hand is a tendon-driven, anthropomorphic robotic platform designed to closely replicate the structure and movement of a human hand. It features 17 degrees of freedom—16 in the fingers and 1 in the wrist—enabling a wide range of dexterous manipulation tasks. Its design balances functionality, reliability, and accessibility.
- Open-Source: All design files (STLs), control software, material lists, and step-by-step assembly instructions (including videos) are publicly available on our dashboard. The project is built to encourage replication, customization, and experimentation by researchers, educators, and hobbyists.- Reliable: The ORCA hand incorporates several design choices focused on robustness and longevity. Joints are engineered to safely dislocate under excess load rather than break, which protects components and simplifies repairs. Additionally, auto-calibration, low-friction tendon routing through the center of rotation of each joint, and a modular layout contribute to consistent performance and long-term usability.
- Cost-Effective: The hand is centered around a 3D-printable design, with a total material cost under 2,000 CHF. All structural components can be printed using a standard 3D printer, and the remaining off-the-shelf parts are widely available and easy to source online, ensuring accessibility for a wide range of users.
- Anthropomorphic: Designed to match the proportions and joint layout of the human hand, the ORCA v1 includes an opposable thumb and an actuated wrist. It mirrors human joint configurations, including MCP, PIP, and ABD joints, enabling it to interact with everyday tools and objects originally designed for human use, and to perform a broad spectrum of manipulation tasks with human-like agility. This anthropomorphic structure also significantly simplifies teleoperation/retargeting and facilitates a more straightforward training on human hand data.
Together, these features make the ORCA v1 hand a practical and versatile platform for hands-on exploration in robotics and manipulation-focused learning and development.
