TESOLLO Inc. this month launched its new humanoid robotic hand, the DG-5F-S. The company said the latest model builds on its proprietary actuator technology, resulting in a more compact and lightweight design than its predecessor while maintaining the core structure.

“Since 2023, TESOLLO has been developing proprietary actuators optimized for humanoid robotic hands, moving away from the use of generic actuators,” stated Youngjin Kim, CEO of TESOLLO. “Our focus has been on achieving high torque density, durability, and maintainability.”

“The DG-5F-S represents a significant advancement of that technology, achieving compactness and lightweight design while enhancing compatibility with various humanoid platforms,” he added.

Founded in 2019, TESOLLO said its name is a combination of “technology” and “sole,” representing its commitment to using technology to open new horizons in the robotic automation market. The Incheon, South Korea-based company was an exhibitor at CES last week.

New model builds on DG-5F robot hand

Like TESOLLO’s flagship model DG-5F, the DG-5F-S features a five-finger, 20 degrees-of-freedom (DoF) configuration. Each finger has four independently driven joints copying the structure of a human hand. This design enables the precise manipulation and dexterity required for humanoid robots, the company asserted.

“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,” Youngjin Kim said.

The DG-5F debuted at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in 2024. Since then, major Korean and global technology companies have adopted the gripper, expanding its use cases across industries.

Now exported to 16 countries, the DG-5F has proven both its technical excellence and market viability, said TESOLLO. The company said it built on that success in developing the DG-5F-S, which is optimized for integration into humanoid platforms through miniaturization and weight reduction.

Weighing under 1 kg (2.2 lb.) and sized comparably to a human hand, the DG-5F-S is compatible with a wide range of humanoid platforms, TESOLLO said.

TESOLLO offers an affordable, accurate option

TESOLLO said the price of the DG-5F-S is about 60% of that of the DG-5F, providing a more accessible option for startups, research institutions, and small to midsize companies.

The DG-5F-S employs a direct-drive mechanism, minimizing backlash and enabling high positional accuracy and intuitive control, the company explained. TESOLLO said its gripping and manipulation algorithms allow for stable handling of objects with diverse shapes and materials.

In addition, the new robotic hand includes support for industry-standard communication protocols to enhance user convenience in real-world environments, according to the company.

TESOLLO offers a variety of customization options, including tactile sensor integration, waterproof covers, and manipulation algorithm tuning. TESOLLO said they make the DG-5F-S suitable for both research and industrial applications.

With the DG-5F-S, TESOLLO aims to accelerate the adoption of humanoid robot hands and expand real-world applications. It described the new end effector as “a key platform driving the transition of humanoid robots from research and prototyping to commercialization, further solidifying TESOLLO’s position in the global robotics market.”

After the prototype debut at CES, TESOLLO plans to officially launch the DG-5F-S in the first half of 2026.
