South Korean robotics company TESOLLO has launched its latest innovation, the DG-5F-S humanoid robotic hand, featuring significant improvements in size, weight, and affordability while maintaining advanced dexterity and functionality.
Key Advancements in the DG-5F-S Model
Building on its predecessor, the DG-5F, the new model maintains the same five-finger, 20 degrees-of-freedom (DoF) configuration with independently driven joints that mimic human hand structure. The key difference lies in its more compact design, weighing under 1 kg (2.2 lb.) and sized comparably to a human hand, making it highly compatible with various humanoid platforms.
According to TESOLLO CEO Youngjin Kim, the company has been developing proprietary actuators specifically optimized for humanoid robotic hands since 2023, moving away from generic actuators. This focus on specialized technology has enabled them to achieve high torque density, durability, and maintainability in their latest offering.
Technical Features and Capabilities
The DG-5F-S employs a direct-drive mechanism that minimizes backlash, allowing for high positional accuracy and intuitive control. TESOLLO has equipped the hand with gripping and manipulation algorithms that enable stable handling of objects with diverse shapes and materials.
The robotic hand also supports industry-standard communication protocols, enhancing user convenience in practical applications. Customization options include tactile sensor integration, waterproof covers, and manipulation algorithm tuning, making the DG-5F-S suitable for both research and industrial use cases.
Market Positioning and Accessibility
A significant advantage of the DG-5F-S is its price point, which TESOLLO states is approximately 60% of the DG-5F model. This more accessible pricing aims to make advanced robotic hand technology available to startups, research institutions, and small to midsize companies.
The company’s flagship DG-5F model, which debuted at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in 2024, has already been adopted by major Korean and global technology companies and exported to 16 countries, demonstrating market validation for TESOLLO’s approach.
Future Outlook
Following its prototype debut at CES, TESOLLO plans to officially launch the DG-5F-S in the first half of 2026. The company positions this new robotic hand as a key platform that will help drive the transition of humanoid robots from research and prototyping to commercial applications.
Founded in 2019 and based in Incheon, South Korea, TESOLLO continues to pursue its mission of using technology to open new horizons in the robotic automation market, as reflected in its name – a combination of “technology” and “sole.”
