DG-5F-S
The DG-5F-S is a high-dexterity, 20-DOF (optional 15-DOF) robotic hand that prioritizes a high strength-to-weight ratio. By reducing the weight to just 880g while maintaining a human-scale 200mm length, it allows humanoid platforms to maintain better stability. It features a direct-drive BLDC architecture that is highly backdrivable, providing inherent mechanical safety and sensitivity for delicate human-robot interaction.

Frequently Asked Questions
Get answers to common questions about this robot
Q1. What is the humanoid robot hand DG-5F-S, and what problem does it solve?
The DG-5F-S is a compact, lightweight robotic hand manufactured by TESOLLO, a South Korean company specializing in robotic grippers. It addresses the challenge of integrating high-dexterity manipulation into space-constrained humanoid robots and mobile platforms by combining full actuation with reduced size and mass compared to earlier models.
Q2. What are the main capabilities and key features of DG-5F-S?
The DG-5F-S features five fingers with 20 degrees of freedom, with each finger independently actuated through four joints. Key features include backdrivable joints for mechanical compliance, built-in tactile and force sensors, fully electric servo-driven motors, and a form factor approximately 21 centimeters in length matching human hand proportions.
Q3. Which industries and use cases is DG-5F-S built for?
According to TESOLLO, the DG-5F-S is designed for humanoid robot integration, research platforms, and industrial automation applications. The company emphasizes integration-oriented optimization for practical deployment scenarios involving weight constraints, mounting interface compatibility, and system configuration flexibility across various humanoid robot platforms.
Q4. What is the grip strength and dexterity of DG-5F-S?
The DG-5F-S delivers a gripping capacity of approximately 6 kilograms for optimal envelop grip and 2.5 kilograms for pinching grip. Its 20 degrees of freedom enable precise, independent finger movement designed to support complex grasping and manipulation motions comparable to human hand dexterity.
Q5. Is DG-5F-S compatible with standard robotic arms?
The DG-5F-S is designed with integration-first engineering principles to ensure compatibility with existing robotic systems. It supports standard industrial communication protocols including Modbus RTU and TCP, facilitating seamless integration with diverse robotic platforms and control systems.
Q6. Does DG-5F-S support tactile sensing or force feedback?
Yes, the DG-5F-S includes built-in tactile and force sensors as standard components. These sensors enable the hand to detect contact, measure applied forces, and provide feedback necessary for compliant manipulation and safe interaction with objects and environments.
Q7. What programming interfaces or SDKs are available for DG-5F-S?
The DG-5F-S supports ROS2 for integration with diverse robotic systems and is compatible with simulation tools including ISSAC and MuJoCo. According to TESOLLO, the hand features a user-friendly software interface and operates at a control frequency of 400 hertz.
Q8. How does DG-5F-S compare to other robotic end-effectors?
TESOLLO states that the DG-5F-S is 20 to 45 percent more cost-competitive than comparable products on the market. The hand emphasizes practical integration requirements over raw specifications alone, incorporating backdrivable joints, compliance features, and optimized mounting interfaces for real-world deployment scenarios.
Q9. What level of maintenance is required for DG-5F-S?
The search results do not provide specific information regarding maintenance requirements, service intervals, or component replacement procedures for the DG-5F-S. Prospective users should contact TESOLLO directly for detailed maintenance and support documentation.
Q10. Is DG-5F-S currently available for commercial purchase?
The DG-5F-S is listed as in production by TESOLLO. The hand is available for purchase, though some retailers indicate backorder status. An optional 15-degree-of-freedom configuration is also available for applications requiring reduced control complexity or smaller form factors.
