Tesollo Inc. today said it is officially commercializing its compact and lightweight humanoid robotic hand, the DG-5F-S. The company developed this updated model based on its dedicated gripper actuator technology.
While maintaining the core structure and manipulation performance of the company’s flagship DG-5F-M, Tesollo redesigned the DG-5F-S with a strong focus on miniaturization and weight reduction. Through this redesign, the company has expanded the range of applications by enabling more flexible responses to the mounting requirements and system configurations. A wide variety of humanoid robot platforms helped to drive these changes, Tesollo said.
Founded in 2019, Tesollo said its name is a combination of “technology” and “sole,” representing its commitment to opening new horizons in the robotic automation market. The Incheon, South Korea-based company originally debuted the DG-5F-S at CES 2026 earlier this year.
Humanoid hand designed for easy integration
Built on a five-finger, 20 degree-of-freedom (DoF) multi-jointed architecture, the DG-5F-S supports precise grasping and manipulation motions required for humanoid robots, said Tesollo. Rather than competing on specifications alone, the company said it has optimized the gripper for integration.
The DG-5F-S reflects practical requirements repeatedly encountered during real deployments, Tesollo said. They include constraints on weight and size, mounting interface conditions, and compatibility with surrounding systems during platform integration.
Tesollo is also introducing an optional five-finger, 15 DoF model. It said this model is suitable for research environments where extremely high degrees of freedom are not essential for hand-motion implementation or where a smaller robotic hand is preferred.
The company explained that it developed the DG-5F-S based on real-world usage data and on-site feedback accumulated through supplying the DG-5F-M to global customers. Tesollo asserted that the DG-5F-S is not a concept product limited to research or demonstrations, but a commercial product designed from validated customer needs, which differentiates it from alternatives.

Tesollo also said it expects the DG-5F-S to help reduce common barriers in adopting robotic hands—particularly cost burden and size constraints. The company said it wants to lower the entry threshold for a wider range of users, including startups, research institutions, and small to midsize companies that have been considering humanoid robotic hands.
Through the commercialization of the DG-5F-S, Tesollo plans to expand robotic hands beyond research platforms into industrial-grade core components that can be reliably integrated into humanoid systems, while strengthening the foundation for humanoid commercialization in Korea.
The company debuted its flagship DG-5F 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.
