How to Choose the Right Dexterous Hand for Your Robotics Project?

As robots move from simple repetitive motion toward more intelligent interaction, the ability to grasp, feel, and manipulate objects is becoming increasingly important.

A conventional gripper may be sufficient for picking up objects of a fixed shape, but many advanced robotic applications require more human-like hand movements. Robots may need to hold delicate items, adjust their grip in real time, rotate objects, perform gestures, or complete tasks involving both precision and force.

The Biohand Dexterous Hand Series provides multiple solutions for robotic manipulation, with different models designed around tactile sensing, force feedback, speed, precision, AI vision, and integration flexibility.

What Is a Dexterous Robotic Hand?

A dexterous robotic hand is an advanced end-effector designed to imitate some of the movements and functions of a human hand.

Unlike a basic two-finger gripper, a dexterous hand usually includes multiple joints and degrees of freedom. This allows it to perform more complex movements, including grasping, pinching, rotating, holding, pressing, and gesture interaction.

Depending on the model, the hand may also include tactile sensors, force sensors, cameras, and intelligent control functions. These features allow the robot to understand not only where an object is, but also how strongly it is being held and whether the grip needs to be adjusted.

Why Is Tactile Sensing Important?

Vision can help a robot locate an object, but vision alone cannot fully understand physical contact.

When handling a fragile component, soft material, irregular object, or slippery surface, the robot needs feedback from the contact area. Tactile sensing helps the hand detect pressure and grip conditions in real time, allowing the control system to make more accurate adjustments.

The RH56E2 can be configured with multiple tactile sensor modules, while the RH56DFTP integrates 17 tactile sensors for more detailed fingertip feedback. For applications requiring more advanced perception, the DexH13 uses hundreds of tactile sensing units to support multidimensional tactile information.

This makes tactile-enabled models suitable for delicate handling, smart manufacturing, laboratory research, and robotic tasks where grip control is critical.

Which Model Is Suitable for Strong and Stable Gripping?

For customers who need a balance of gripping force, tactile feedback, and reliable operation, the RH56E2 is a practical option.

It features a six-degree-of-freedom structure with 12 joints and provides strong fingertip output. Its power-off self-locking design helps the hand maintain a stable state when power is interrupted, while eliminating the need to return to the home position after every restart.

This can be valuable in industrial research, service robotics, and applications where the hand must hold objects securely and resume operation efficiently.

The RH56E2 also supports commonly used communication options, making it easier to integrate into different robotic systems.

Which Dexterous Hand Is Better for High-Precision Tasks?

For fine manipulation and repeatable robotic motion, the RH56DFX focuses on precision and control.

Its human-like structure, multiple joints, force sensing, and sub-millimeter repeatability make it suitable for tasks requiring consistent positioning and careful object handling. It also supports ROS integration, helping developers connect the hand with existing robot control, perception, and motion-planning systems.

Possible applications include robotic research, prosthetic development, human-robot interaction, delicate assembly, and experimental manipulation tasks.

For development teams already working within a ROS-based environment, the RH56DFX offers a more convenient path toward system integration and secondary development.

What If the Application Requires Both Speed and Dexterity?

Some robotic applications require more than accurate positioning. They also need fast finger movement and smooth dynamic interaction.

The RH56BFX is designed for high-speed, precise hand motion. With six degrees of freedom, 12 joints, force feedback, and sub-millimeter repeatability, it can support rapid gestures and intricate movements.

This makes it suitable for gesture interaction, demonstration robots, human-robot communication, educational research, entertainment systems, and experimental tasks such as robotic instrument playing.

For customers developing robots that must respond quickly while maintaining natural hand movements, the RH56BFX provides a balance between speed, sensitivity, and control.

How Can AI Vision and Advanced Touch Improve Robotic Manipulation?

For more complex embodied AI and autonomous manipulation projects, the DexH13 combines tactile perception with an AI hand-eye vision system.

It features a four-finger, multi-joint structure with 13 degrees of freedom. Its multidimensional tactile system can detect different types of contact information, while its integrated AI camera supports real-time object recognition and position estimation.

The combination of vision and touch allows the robot to understand both the surrounding scene and the physical interaction taking place at the fingertips.

With precise position and force control, a payload of up to 5 kg, and an industrial-grade operating life, the DexH13 is suitable for demanding applications such as warehouse handling, industrial manufacturing, medical research, commercial services, and home automation.

It is especially valuable for teams studying embodied AI, vision-tactile fusion, imitation learning, and autonomous robotic manipulation.

Which Model Is Suitable for Tactile-Sensitive Manufacturing Tasks?

The RH56DFTP is designed for applications that rely heavily on fingertip feedback.

Its 17 tactile sensors provide real-time contact information, helping the robot adjust its grip more carefully during manipulation. With strong fingertip force and a service life exceeding one million operating cycles, it can support repeated use in smart manufacturing and automation environments.

This model is suitable for tasks involving sensitive components, variable object shapes, precision gripping, and operations where consistent tactile feedback can improve reliability.

For customers who prioritize touch perception without requiring the more advanced visual system of the DexH13, the RH56DFTP offers a focused tactile manipulation solution.

How Should You Select the Right Dexterous Hand?

The right model depends on what the robot needs to do.

Choose the RH56E2 when the project requires strong gripping, power-off self-locking, and flexible communication options.

Choose the RH56DFX when precision, force sensing, human-like motion, and ROS integration are the main priorities.

Choose the DexH13 when the application requires advanced multidimensional tactile sensing, AI vision, precise force control, and higher payload capacity.

Choose the RH56BFX when fast finger movement, gesture interaction, and dynamic robotic performance are important.

Choose the RH56DFTP when the task depends on detailed tactile feedback, reliable fingertip control, and repeated operation in smart manufacturing environments.

What Applications Can These Dexterous Hands Support?

The Biohand series can be integrated into humanoid robots, robotic arms, service robots, research platforms, and customized automation systems.

Potential applications include embodied AI research, industrial manipulation, warehouse sorting, component assembly, prosthetic research, medical robotics, gesture interaction, education, commercial services, and home automation.

Because different projects have different requirements, the product range allows developers to select a hand based on required speed, precision, tactile capability, payload, communication method, and software environment.

Building Robots That Can See, Feel, and Act

A capable robot needs more than accurate arm movement. It also needs an end-effector that can interact with real objects safely and intelligently.

The Biohand Dexterous Hand Series offers multiple approaches to robotic manipulation—from strong and stable gripping to high-speed motion, force feedback, multidimensional touch, and AI-assisted visual perception.

By selecting the appropriate model, robotics teams can reduce integration difficulty and build systems that move beyond basic pick-and-place operations toward more flexible, human-like interaction with the real world.
