DexRobot

DexRobot’s flagship product, the DexHand021, is described as a five-fingered industrial-grade dexterous hand with 19 degrees of freedom (DoF) and 23 sensors, capable of high precision manipulation such as solving a Rubik’s cube, grasping multiple objects simultaneously, and operating standard tools. These features position the company to address important trends in robotics: human-scale manipulation, tactile sensing, end-effector modularity, and advanced automation.

Design and Features

Mechanical and Structural Design

DexRobot’s design philosophy centres on modularity, high DoF (degrees of freedom), multi-modal sensing, tool compatibility and ease of maintenance. According to the company website, the DexHand021 features a tendon-rope elastic under-actuated technology combined with 19 actuated joints and multi-modal perception (vision + tactile + force) in order to enable fine manipulation tasks.

The structural design emphasises compatibility with standard robotic arms, low power consumption, manageable maintenance and high integration. For example, the description notes that the hand is “easy to maintain and travel­compatible” meaning it is built for mounting on a variety of robot arms or manipulation systems.

• 19 degrees of freedom (DoF) for the flagship DexHand021 model, enabling near-human finger articulation.
• Multi-modal perception: integration of 23 sensors providing tactile feedback, vision, force measurement and environment interaction.
• High-precision tool handling: The hand is capable of using common tools, manipulating Rubik’s cubes, and handling multiple objects simultaneously, indicating advanced manipulation prowess.
• Compatibility and maintenance: Designed for industrial deployment, the hand emphasises easy maintenance, modular parts and mounting with standard robot arms.
• General-purpose dexterity: Rather than a single-purpose gripper, the platform is built for general manipulation tasks, bringing dexterous manipulation closer to human-level performance in industrial settings.

Technology and Specifications

Core Technologies

DexRobot leverages a confluence of advanced robotics subsystems: high-DoF actuators, tendon-rope driven mechanisms, multi-sensor arrays (tactile, force/torque, vision), embedded control systems, perception pipelines, and motion planning algorithms. The company frames its offering as a “dexterous operation system with general intelligent multi-modal tactile and visual perception.”

The technology stack goes beyond mere mechanical articulation; it includes perception and control loops enabling fine manipulation, tool use, and interactive operations with the environment—key for applications such as industrial-automation, service robotics, research demonstrations or end-effectors in robotic arms.

Representative Specifications

While detailed public datasheets are limited, the company provides certain representative figures for the DexHand021:

• 19 actuated DoF and 5 kinds of perception modalities.
• 23 sensors integrated into the hand module, handling tactile, force and vision feedback.
• Capable of complex manipulations such as solving a Rubik’s Cube with one hand in demonstration, and grasping multiple objects simultaneously—indicating high speed, control and precision.

Because the product is industrial grade, further specifications such as mounting standard (e.g., flange interface), robotic arm compatibility, communication protocol, power consumption, and weight are likely defined in customer-facing datasheets.

Integration & Ecosystem

DexRobot emphasises compatibility with industrial robotic arms and automation systems. Its modular design supports integration in robot work-cells, research rigs, service robotics platforms or collaborative robot systems. It positions itself in the ecosystem of “dexterous end-effectors for industrial robot arms” rather than standalone robots, which can reduce cost and development risk for integrators.

Applications and Use Cases

Industrial Automation & Manipulation

DexRobot’s dexterous hands are especially relevant to advanced automation tasks where standard two-finger or gripper end-effectors cannot handle complex manipulation. Examples include tool handling (e.g., screw-drivers, wrenches), assembly of irregular or unsymmetrical parts, multi-object grasping, and high-precision tasks in electronics manufacturing or small parts assembly. The ability to manipulate multiple objects or tools expands the scope of robotic automation.

Research & Humanoid Robotics

Research institutions and robotics labs exploring humanoid robots, teleoperation, prosthetic end-effectors and advanced manipulation tasks can make use of DexRobot’s high‐DoF hands and multi-modal perception. The platform supports dexterous research such as human-robot interaction, tactile manipulation, imitation learning and AI-driven control of complex hands.

Service Robotics & Human-Scale Interaction

Because the hands provide human-like articulation, they are also suitable for service robotics, where robots interact in human environments and use tools or perform tasks previously reserved for human hands. For example, in logistics, retail, healthcare or home assistance, the need for dexterous handling (cutlery, cups, surgical tools, delicate parts) is significant.

Demonstration & Shows

DexRobot’s hands have been showcased at major industry events such as the World Artificial Intelligence Conference 2025 (WAIC 2025) in Shanghai, where the company displayed its products (including the DexHand021) in live manipulation demonstrations and interactive human-robot demonstration.

Advantages / Benefits

• Enhanced Dexterity: With 19 DoF and multi-modal perception, the DexRobot hands have far greater manipulation capability than conventional grippers, enabling complex tasks.
• Industrial-Grade Compatibility: Designed for mounting on robot arms, with industrial robustness, maintenance ease and mounting standardisation.
• Multi-Modal Sensing: The integration of tactile, force and vision sensors allows more nuanced interaction with environment and objects—enhancing autonomy, precision and reliability.
• Tool and Object Versatility: Capable of using tools and handling multiple objects simultaneously, broadening the range of automation possibilities.
• Research-Ready Platform: For labs and robotics integrators, the ability to access advanced end-effectors accelerates development of new manipulation tasks and service robots.
• Cost-Effective Sub-System: By focusing on the dexterous hand rather than full robots, DexRobot offers a manageable entry point for integrators seeking advanced capabilities without building full platforms.

Comparisons

When compared to other robotic hand or end-effector providers, DexRobot’s high DoF and multimodal perception place it in a more advanced segment. For example:

• Compared with standard two-finger grippers or three-finger adaptive hands, DexRobot offers significantly higher articulation and sensory feedback, enabling more human-like manipulation.
• Versus research-only robotic hand platforms (often low volume, very expensive), DexRobot emphasises industrial grade, maintainability and compatibility with standard robot arms.
• Compared to robotic companies that build full humanoid robots, DexRobot focuses on the end-effector subsystem—making it suitable for integrators specialising in robot arms rather than full humanoid development.

Thus, DexRobot occupies a niche between simple grippers and full humanoid platforms, targeting advanced manipulation subsystems for industrial or research use.

Pricing and Availability

As of the present time, specific public pricing for DexRobot’s flagship DexHand021 model is not widely published online. The company provides contact and quotation services via its website. Typical pricing for advanced dexterous end-effectors in industry suggests substantial cost (tens of thousands of dollars or more) depending on configuration, sensors, communication protocols, mounting integration and support.
