Its customers range from universities and research institutes to global manufacturers, robotics startups, system integrators, and production sites of major corporations.
Interview with Jaegyeong LEE, General Manager at Tesollo.
What are the main areas of activity of the company?
Jaegyeong LEE: Tesollo’s business is broadly divided into two areas: robot hand product sales and robotic automation solutions.
First, Tesollo develops and manufactures multi-joint robotic grippers and robotic hands, including the DG-3F, DG-4F, and DG-5F, and supplies them to distributors, system integrators, robot manufacturers, research institutes, and universities. Customers integrate these products into their own robotic systems and automation equipment. The DG-5F series is also used by leading institutions such as Stanford University, the University of Toronto, and ETH Zurich, showing its value as a platform for AI-based manipulation, reinforcement learning, teleoperation, and humanoid robotics research.
Second, Tesollo provides robotic automation solutions for manufacturing and logistics sites. The company analyzes customer tasks and configures suitable automation systems using its robotic hands and grippers. One example is parts kit preparation before production-line input, where different parts with varying sizes, shapes, weights, and surface materials can be handled by a single multi-joint robotic hand through force and finger-angle control.
This solutions business can expand beyond initial system implementation into maintenance, technical support, software updates, process improvement, and long-term recurring revenue.
What’s the news about new products/services?
J.L: The most important recent development is the full-scale market launch of the DG-5F series, Tesollo’s five-finger robotic hand platform.
The DG-5F is a multi-joint robotic hand with five fingers and 20 independently actuated degrees of freedom. It is designed not only for grasping objects, but also for manipulation, enabling the hand to change an object’s orientation and position within the hand.
Across the series, the DG-5F features a human-like size and structure. Its direct-drive actuation reduces backlash and response delay, while allowing real-time monitoring of status data such as position, velocity, torque, and temperature. These capabilities make it applicable to various tasks, including assembly, parts alignment, tool use, and handling of irregularly shaped objects.
The DG-5F-M is a high-performance model designed for industrial applications. It is suitable for manufacturing automation, logistics, precision assembly, and tool-use applications. Optional tactile and force sensors enable more stable control, including contact detection, slip recognition, and pressure adjustment.
The DG-5F-S is a compact and lightweight model designed for humanoid robots and research platforms. Weighing less than 1 kg and featuring a compact structure, it can be easily integrated into various humanoid platforms. It has been developed for research institutes and startups working on AI-based manipulation, teleoperation, reinforcement learning, and object manipulation data collection.
What are the ranges of products/services?
J.L: The Delto Gripper product family consists of five product lines, ranging from industrial robotic grippers to advanced humanoid robotic hands, addressing diverse automation and robotics needs.
Among them, the DG-3F and DG-5F series represent Tesollo’s core technologies and flagship solutions.
The DG-3F is one of Tesollo’s flagship products, capable of handling objects with various shapes and sizes that are difficult for conventional two-finger grippers. It is widely used in assembly, kitting, sorting, and logistics automation applications.
The DG-5F series is Tesollo’s flagship humanoid robotic hand product line. The DG-5F-M is designed for industrial applications requiring durability, payload capacity, precision assembly, tool use, and complex manipulation. The DG-5F-S is a compact and lightweight model optimized for humanoid robots, AI manipulation research, teleoperation, and humanoid robotics development.
Tesollo provides not only hardware but also software technologies. The company has developed pick-point and grasp-point generation technologies for bin-picking, as well as AI-based object manipulation technologies for grasp stability and dexterous manipulation, offering these solutions to industrial users and researchers worldwide.
What is the state of the market where you are currently active?
J.L: Tesollo currently operates in two major markets: industrial automation and humanoid/AI robotics.
In industrial automation, Tesollo is working with manufacturing and logistics companies on PoC and demo projects. Some solutions have already moved beyond research and testing and are being applied in actual mass-production processes. The market is shifting from asking whether a task can be automated to evaluating productivity, quality stability, and cost-saving benefits for commercial deployment.
The humanoid robot market is also growing rapidly. As humanoid companies develop platforms for real-world industrial applications, demand is increasing for robotic hands with human-like size and functionality.
Tesollo is collaborating with several humanoid companies to integrate the DG-5F series into various platforms and validate their task performance through demos and application projects. The market is now moving beyond simply building humanoid robots to verifying what tasks they can perform reliably.
Tesollo believes that industrial automation and humanoid robotics will become increasingly connected. Manipulation technologies proven in manufacturing environments will expand into humanoid robots, while AI-based manipulation technologies developed for humanoids will be applied back to industrial automation.
What estimations do you have for the second half of 2026?
J.L: Tesollo has been growing rapidly year after year. Revenue grew by 245% in 2024 compared to 2023, and the company continued its strong growth momentum in 2025, achieving 359% year-over-year growth.
In the second half of 2026, demand for multi-joint robotic hands and intelligent grippers is expected to continue increasing across industrial automation, AI robotics, and humanoid robotics. Tesollo plans to expand its products and solutions centered on the DG-3F and DG-5F series for manufacturing and logistics applications, while increasing real-world use cases that demonstrate productivity, stability, and economic value based on ongoing PoCs and demonstrations.
In particular, through expanded collaboration with humanoid robotics companies and the development of real factory deployment cases, Tesollo believes the robotic hand and intelligent gripper market is entering a critical inflection point toward mass production. Accordingly, 2026 is expected to be a year of full-scale investment in production capabilities and infrastructure to support this transition.
