INSPIRE RH56 Series: Robot Hands with the Delicacy of Human Hands

The RH56 series robot hands from INSPIRE-ROBOTS are five-fingered robots that implement sophisticated movement and force control just like a human hand. They are specialized for picking up small objects or performing delicate motions by precisely controlling the joints of each finger.

By embedding 6 miniature actuators and 6 pressure sensors, they create 6-DoF (12 joints) of movement. They are easy to integrate into various robot systems, including ROS compatibility. Most of all, their lightweight structure (weighing approx. 0.5–0.65kg), which is similar in size to a human hand, makes them attractive as they can be mounted on collaborative robots without any issues.

There are several models in the RH56 series depending on the application. Each model has such a distinct personality that they even have nicknames.

RH56BFX – The “Pianist” Model: This model focuses on high-speed movement and precise interaction. Although the grip force is somewhat low, the finger movements are so fast and sophisticated that it is used for piano-playing robots or demonstrations of gesture interaction with humans.

It is characterized by being agile enough to press complex piano keys as its name suggests. (The maximum finger bending speed reaches up to 570°/s!) Thanks to this, it is loved in fields where delicacy is important, such as service robots or artistic performance robots.

RH56DFX – The Industrial “Gripper” Model: This model has a strong grip force with moderate speed. It is strong enough to stably grasp objects weighing up to approx. 1kg with one hand, making it suitable for the role of an industrial gripper moving heavy parts or for robotic prosthetics that require human-like hand strength.

For example, it is useful for gripping metal parts on a production line or holding heavy tools mounted at the end of a robot arm. While its movement speed is slower than the Pianist model due to its strength, it allows for precise force control, enabling it to hold objects firmly without pressing too hard.

RH56DFTP – The Advanced “Tactile Feedback” Model: As the flagship of the RH56 series, this model is equipped with a total of 17 tactile sensors throughout the fingers. Thanks to these sensors, it can detect and provide feedback on even minute force changes in real-time when touching an object.

The maximum grip force has also been significantly improved to approx. 3kg (30N), combining both precision and power. This allows it to be deployed in delicate assembly tasks or handling fragile objects that seem to require direct human intervention. For instance, it is perfect for tasks where tactile sensation is vital, such as a robot hand tightening small screws in a smartphone assembly process or a rehabilitation robot hand in contact with patients in the medical field.

As such, the INSPIRE RH56 series consists of models with diverse personalities, from the “fast-moving Pianist” to the “strong industrial gripper” and the “sensory delicate hand.” They commonly provide ROS support and RS485/Modbus communication interfaces for easy integration with robot systems, and their modular design ensures easy maintenance.

The application fields are very broad, making it a versatile robot hand series that can be chosen and used for everything from entertainment or research robots to assembly lines in smart factories and prosthetics for the disabled. (Detailed inquiries can be made through Marosol, and you can also receive demos and technical materials for each model during deployment consultations.)

Tesollo DG Series: The Versatility of 3-Finger Grippers vs. 5-Finger Robot Hands

The Delto Gripper series from TESOLLO, specifically the DG-3F (3-Finger) and DG-5F (5-Finger) models, are products that demonstrate the possibilities of robot hands with different finger counts and approaches. Tesollo is a company with specialized robot gripper technology that started as a Korean startup.

The DG-3F and DG-5F are Tesollo’s masterpieces; one is a universal industrial gripper, and the other is a humanoid robot hand in the shape of a human hand. Both models support standards such as 24V power and Modbus communication, and with a fast response frequency of 400–500Hz, they are spotlighted in smart factory sites as they can be easily integrated into various robots. Now, let’s look at their features.

DG-3F – 3-Finger Universal Gripper: This is an electric gripper consisting of a cylindrical body with 3 fingers and 12 joints (4 joints x 3). Although it has fewer fingers, its structure is robust and flexible, with its greatest strength being versatility in handling objects of various shapes and sizes with a single gripper.

For example, a single DG-3F can pick up anything from thin cards or paper to fragile objects like eggs and heavy metal parts (up to approx. 10kg!). Even irregularly shaped parts, which are difficult for general 2-finger grippers, can be handled continuously without a tool changer because the three fingers provide balanced grasping. Due to these characteristics, it is widely used in production lines of smart factories and logistics automation systems.

In fact, there are cases where efficiency was increased by solving a production process that handles various parts at once with a single DG-3F instead of replacing grippers for each item. Additionally, its modular design provides excellent durability, being designed to withstand over 1 million repeated operations, which also reduces maintenance costs.

DG-5F – 5-Finger Humanoid Hand: This is a five-fingered robot hand designed to be almost the same size as an adult male hand (approx. 20cm in hand length). 20 joints (4 joints per finger) are each independently driven, providing a level of freedom and movement flexibility virtually identical to a human hand. Its appearance is also similar to a human hand, so when mounted on two robot arms, it can implement sophisticated tasks just like a person's hands. (Refer to the GIF below)

The advantage of the DG-5F is, above all, that it “does things that are difficult to do like a human on behalf of humans.”

For instance, it is showing its true value in tasks using tools. It can grip and turn tools like screwdrivers or pliers, and can handle various objects with a pinch grip (picking with fingertips), power grip (holding tightly like a fist), or precision grip (partial picking), enabling tasks that were difficult with existing simple grippers.

Because of its independent joint control, it can also implement complex hand gestures, so it is widely used in humanoid robot research or human motion-mimicking AI research. Furthermore, it shows attention to compatibility with the latest robot systems by supporting ROS2, etc.

In summary, the Tesollo DG-3F is a multi-talented gripper for industrial sites, and the DG-5F is a versatile robot hand close to a human hand. Both models are officially supplied through Marosol with technical support. In the field, the 3-finger gripper DG-3F is popular as a solution for increasing process efficiency by handling various parts with one unit, while the 5-finger hand DG-5F is playing an innovative role in advanced R&D or high-value-added manufacturing processes.

RH56 vs. DG Series Feature Comparison – Who is Strong Where?

Now, let’s compare the INSPIRE RH56 series and the Tesollo DG series directly and see which is more suitable for which purpose. While both product lines are excellent, they have different areas of expertise, leading to different pros and cons. Let’s summarize the key comparison points!

👉 Speed and Delicate Control: For tasks requiring fast hand movements like the RH56 “Pianist” model, the RH56 series is advantageous. The agility and sophistication required to actually play the piano are areas difficult to mimic even with the multi-jointed DG-5F. For example, the fast response of the RH56 is suitable for service robot hands that assemble small parts at ultra-high speeds or communicate naturally with humans through gestures.

👉 Grip Strength and Load: In terms of force for handling heavy objects, the Tesollo DG series leads. The DG-3F can lift up to 10kg with one hand, and the DG-5F can also withstand loads in the double-digit kilogram range. On the other hand, the RH56 series is suitable for objects within a maximum of several kilograms depending on the model (e.g., approx. 1kg for the DFX model, ~3kg for the DFTP model). Therefore, the DG-3F is perfect for industrial grasping tasks requiring great force (e.g., gripping heavy machine parts or tools), while the RH56 is sufficient for tasks centered on small precision parts or light objects.

👉 Size and Installation Constraints: The size of the robot arm to be mounted or environmental constraints can also affect product selection. The RH56 series, with its light weight of around 0.5kg and compact size, can be used without burden on small collaborative robots or mobile robots. On the other hand, the DG-5F is heavy at approx. 1.5kg and its physical size is as large as a human hand, so mounting it requires a sturdy robot arm or sufficient workspace. The DG-3F weighs about 1kg, which is in the middle, and can be easily attached to most industrial robot arms.

If the robot's payload (extra load capacity) is small, the RH56 is advantageous, and if the payload capacity is large, the DG-5F is also worth considering. Environmental factors such as dust/waterproofing should also be checked; while both product lines are designed to withstand general factory environments, there are slight differences in extreme temperature and humidity. (e.g., the DG-3F can operate from -20 to +100°C, even withstanding work in frozen warehouses, while the DG-5F has a slightly narrower range of -5 to +60°C for electronic protection). Since these details can be coordinated in advance through the Marosol technical support team, it is advisable to get a recommendation for a product suitable for your work environment through a consultation before adoption. 😉
