DG-4F
Last updated:
The DG-4F is Tesollo’s fully actuated 4-finger robotic gripper with a novel mechanical design and multi-joint structure, integrating functions of a right-hand gripper, left-hand gripper, and parallel gripper into one versatile product. It enables precise, stable grasping of sensitive components like display panels, supports shape adaptability for various objects, and is suitable for research, humanoid robots, and industrial tasks such as film peeling, assembly, and packing, reducing gripper changeover time and costs.

DG-5F-S
By: TESOLLO
Launched: 2026
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.
DG-3F-M Delto Gripper
By: TESOLLO
Launched: 2025
The DG-3F Delto Gripper is a next-generation 3-finger robotic hand with 12 degrees of freedom (4 DoF per finger), designed for dexterous grasping in assembly, manufacturing, and research. Featuring slimmer fingers (40% thinner than prior models), doubled torque output, and embedded grasping algorithms, it supports multiple grip modes like pinch, parallel, and envelop grasps. Compatible with TM Robot, Universal Robots, and others, it handles diverse objects from thin paper to 10 kg payloads with individual joint servo control.
DG-5F-M
By: TESOLLO
Launched: 2025
The DG-5F Delto Gripper is a fully actuated, 5-finger anthropomorphic robotic hand with 20 degrees of freedom (4 DoF per finger), designed for human-level dexterity in grasping and manipulation. Comparable in size to an adult male hand (approx. 200 mm length), it features independent joint control, direct-drive BLDC motors, absolute encoders, and supports pinch/power/precision grips. Built for research, industrial, and humanoid applications, it offers high-speed control (up to 500 Hz), optional tactile sensors, and ROS2 integration for precise tool use and object handling.
Frequently Asked Questions

Q1. What is the humanoid robot hand DG-4F, and what problem does it solve?
The DG-4F is a four-finger multi-joint robotic gripper developed by TESOLLO. According to the manufacturer, it addresses challenges in handling delicate components like display panels by enabling precise gripping and automation in manufacturing processes.
Q2. What are the main capabilities and key features of DG-4F?
The DG-4F features a four-finger articulated structure that integrates right-hand, left-hand, and parallel gripping functions. TESOLLO states it supports high-precision control for tasks including gripping, assembly, and packing of sensitive parts.
Q3. Which industries and use cases is DG-4F built for?
TESOLLO designed the DG-4F for display manufacturing, such as automated film peeling on panels, as well as applications in electronics, logistics, and humanoid robotics. It targets precision handling of shock-sensitive components.
Q4. What is the grip strength and dexterity of DG-4F?
The DG-4F offers dexterity through its multi-joint four-finger design with 18 degrees of freedom. According to TESOLLO product details, it provides precise control suited for delicate operations, though specific grip strength figures are not publicly detailed.
Q5. Is DG-4F compatible with standard robotic arms?
Yes, the DG-4F integrates with various robotic systems, including collaborative and industrial robots. TESOLLO indicates compatibility via standard interfaces like Modbus protocol and ISO 9409-1 adapter frames used in their gripper lineup.
Q6. Does DG-4F support tactile sensing or force feedback?
TESOLLO has not specified tactile sensing or force feedback for the DG-4F in available documentation. It relies on high-precision joint control for handling sensitive parts, similar to other models in the Delto series.
Q7. What programming interfaces or SDKs are available for DG-4F?
The DG-4F supports control via Modbus protocol in operator mode and TCP/IP in developer mode, per TESOLLO's gripper FAQs. It also accommodates ROS and ROS2, as with compatible Delto Grippers.
Q8. How does DG-4F compare to other robotic end-effectors?
Unlike single-function grippers, the DG-4F combines multiple grip types in one unit, reducing tool changes. TESOLLO positions it as versatile for complex tasks versus simpler parallel or three-finger models like DG-3F.
Q9. What level of maintenance is required for DG-4F?
TESOLLO describes its grippers, including models like DG-4F, as having modular designs for durability and ease of maintenance. Specific routines involve standard checks on joints and motors, with support available via company channels.
Q10. Is DG-4F currently available for commercial purchase?
TESOLLO announced the DG-4F for commercial release in September following its exhibition unveiling, with pre-orders underway at that time. Availability status as of 2026 should be confirmed directly with the manufacturer.
