Tesollo, a domestic robot gripper specialist, announced on the 13th that its developed 'Humanoid Multi-Joint Robot Hand DG-5F (Delto Gripper-5F)' was finally selected as one of the '2025 Korea's Top 10 Mechanical Technologies of the Year' hosted by the Korea Federation of Machinery Industry Societies.
The "Korea's Top 10 Mechanical Technologies of the Year" program recognizes and awards outstanding domestically developed mechanical technologies. Selection is based on a comprehensive evaluation of the technology's innovation, difficulty, and contribution to industry. Tesolo submitted the DG-5F upon the recommendation of the Korea Institute of Industrial Technology, and it received high praise for its technological sophistication and industrial application in the field of humanoid robot components.
The DG-5F is a humanoid robotic hand with five fingers identical to the human hand and 20 active joints (20 degrees of freedom). It can grasp, assemble, transport, and manipulate objects of various shapes and textures with precision. Its single-module structure, integrating the motor, driver, encoder, and reducer, enhances manufacturing efficiency and maintainability. With a repeatability accuracy of 0.1° and a joint speed of 75 rpm, it ensures reliable operation even in industrial environments.
Beyond its hardware architecture, Tesolo has independently implemented sophisticated control technologies, including high-speed multi-drop communication protocols, in-hand manipulation, and force-based gripping algorithms. This has enabled Tesolo to perform even manual processes that were previously difficult for automated systems to replace. The DG-5F is being utilized not only in industries requiring human dexterity, such as manufacturing, logistics, and assembly, but also as a research platform for collecting human behavioral data for global AI companies.
Tesolo has established a mass production system for the DG-5F and is supplying it to leading research institutions, including Stanford University, ETH Zurich, and KAIST, as well as global manufacturing companies. Global orders for the DG-5F are increasing, driven by the recent growth of the humanoid market and the increasing demand for atypical automation.
A Tesolo official stated, “Through this award, the technological level of Korean multi-joint robot hands has been recognized worldwide,” and “Based on the DG-5F, we plan to accelerate global standardization and entry into the humanoid robot market.”
