The Rise of Humanoid Hands: Tesollo’s DG-5F-S and the Future of Robotics
South Korean robotics firm Tesollo Inc. Has officially launched its compact and lightweight humanoid robotic hand, the DG-5F-S, marking a significant step toward more accessible and capable humanoid robots. This isn’t just about a new product; it signals a broader trend of focusing on practical integration and cost-effectiveness in the robotics industry.
Miniaturization and the Demand for Humanoid Integration
The DG-5F-S builds upon Tesollo’s existing DG-5F-M model, but with a key difference: a strong emphasis on miniaturization and weight reduction. This redesign addresses a critical require in the humanoid robotics space – the ability to seamlessly integrate robotic hands with a variety of platforms. A sub-1 kg design and human-hand-like form factor are crucial for efficient operation and broader application.
This focus isn’t accidental. Tesollo developed the DG-5F-S based on feedback from customers and real-world deployment data. The company recognized that specifications alone aren’t enough; practical considerations like size, weight and mounting interfaces are paramount for successful integration.
Two Models for Diverse Needs: 20-DoF and 15-DoF
Tesollo is offering the DG-5F-S in two configurations: a 20-degree-of-freedom (DoF) model and a 15-DoF version. The 20-DoF model provides maximum dexterity and precision, ideal for complex tasks like tool use and assembly. The 15-DoF model offers a more streamlined solution for research environments where extremely high degrees of freedom aren’t essential, or where a smaller hand is preferred.
This dual-model approach demonstrates a commitment to serving a diverse range of users, from research institutions to industrial applications.
Cost-Effectiveness: Lowering the Barrier to Entry
One of the most compelling aspects of the DG-5F-S is its projected cost. Planned at approximately 60% of the price of the DG-5F, it aims to make advanced robotic hands accessible to a wider audience, including startups, research labs, and small to mid-sized organizations. This is a crucial step in democratizing access to sophisticated robotics technology.
Tesollo’s goal is to move beyond research platforms and establish robotic hands as reliable, integrated components in industrial-grade humanoid systems.
Direct Drive Actuation and Enhanced Reliability
The DG-5F-S utilizes a Direct Drive mechanism, minimizing backlash and providing high positional accuracy. This, combined with built-in grasping and manipulation algorithms, enhances robustness in real-world usage, enabling stable handling of objects with diverse shapes and materials. This focus on reliability is essential for practical applications.
The Expanding Ecosystem of Humanoid Robotics
Tesollo’s advancements approach at a time of growing interest in humanoid robotics. The company debuted its flagship DG-5F at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in 2024, and has since seen adoption by major technology companies. This suggests a maturing market and increasing demand for capable humanoid components.
The DG-5F-S is designed to support industrial communication protocols (Modbus RTU/TCP), further enhancing its practicality and efficiency for industrial applications.
Future Trends in Robotic Hands
Increased Focus on Tactile Sensing
While the DG-5F-S excels in grasping and manipulation, the next generation of robotic hands will likely incorporate more advanced tactile sensing. This will allow robots to “feel” objects, providing crucial feedback for delicate tasks and improving their ability to adapt to unpredictable environments.
AI-Powered Grasping and Manipulation
Artificial intelligence will play an increasingly important role in robotic hand control. AI algorithms can learn optimal grasping strategies, adapt to different object properties, and even predict potential failures, leading to more robust and efficient manipulation.
Bio-Inspired Designs
Researchers are drawing inspiration from the human hand to create more natural and versatile robotic grippers. This includes exploring underactuated designs, which mimic the flexibility and adaptability of human fingers.
