Tesollo (CEO Youngjin Kim), a robotics gripper specialist, announced on the 5th that it has developed “DG-5F-S,” a humanoid robot hand that is a compact and lightweight version of its existing flagship product. The product is scheduled for an official launch in the first half of this year, and a prototype will be unveiled for the first time at CES 2026.

DG-5F-S is characterized by its compact and lightweight design achieved by advancing Tesollo’s in-house actuator technology for robotic hands, while maintaining the core structure of the existing model.

Like the existing DG-5F, it retains a five-finger, 20-degree-of-freedom (DoF) structure, applying the same human-like configuration in which each of the five fingers is independently driven by four joints. This enhances the precise manipulation performance and agility required for humanoid robots.

With an ultra-lightweight design under 1 kg and a compact size close to that of an adult human hand, it is designed to be naturally integrated into a wide range of humanoid robot platforms. In addition, depending on customer requirements, it supports expansion options such as tactile sensor integration, waterproof covers, and customization of manipulation algorithms, enabling broad applicability from research use to real process deployment.

By adopting a Direct Drive mechanism, it minimizes backlash and provides high positional precision and an intuitive control environment. It can also stably grasp and manipulate objects of various shapes and materials through algorithms, and improves usability by supporting communication protocols proven in industrial sites.

Tesollo expects the price to be set at about 60% of the DG-5F, significantly reducing the adoption burden for startups, research institutions, and small to mid-sized enterprises.

Previously, Tesollo launched the 20-DoF humanoid hand DG-5F in 2024, based on its self-developed actuator technology, and unveiled it for the first time at the International Conference on Intelligent Robots and Systems (IROS) in the same year. DG-5F has been exported to 16 countries worldwide, proving its technological competitiveness and marketability.

CEO Youngjin Kim said, “Moving away from the conventional approach of applying widely used general-purpose actuators, we have been developing dedicated actuators optimized for humanoid robot hands in-house since 2023,” adding, “DG-5F-S is a model that further advances that technology to achieve compactness and light weight, greatly improving integration with various humanoid platforms.”
