High Load Capacity

The O7B offers outstanding load performance. The maximum grasping force of the five fingers reaches 60 N, while the maximum fingertip force of the thumb and each of the four fingers reaches 14 N.

This level of force allows the hand to securely grasp and manipulate objects of various weights, supporting a wide range of tasks from precision assembly to light industrial operations.

Its strong load capacity is enabled by the advanced worm-gear transmission design, which provides high output torque and excellent self-locking capability, ensuring stability and safety when handling loads. 

 Precise Control

The O7B delivers highly precise control thanks to its high repeatability positioning accuracy (less than ±0.2 mm) and advanced control system.

It supports CAN and RS485 industrial bus interfaces, with communication speeds of up to 1 MHz, ensuring fast, stable command transmission and real-time response.

Combined with a force–position hybrid control algorithm, the dexterous hand can simulate delicate human hand operations such as precise grasping and flexible pinching, making it ideal for high-precision research and industrial tasks.

 Compact Structure & Efficient Transmission

The O7B adopts a worm-gear transmission mechanism, offering several advantages:

 Compact structure

Large transmission ratio

Strong self-locking capability (prevents reverse motion under certain conditions)

Smooth and stable operation

This design allows the dexterous hand to maintain high torque output and precision while minimizing overall size and weight.

The complete system weighs only 634.5 g.

With 7 active joints and 10 passive joints, the hand achieves complex motion capability and adaptive grasping while balancing control complexity and cost efficiency.

 Product Functions

Position Control

The system can precisely control the spatial position of the entire hand and each finger joint.

It can smoothly execute predefined trajectory movements, ensuring high positional accuracy from overall hand motion to fine single-joint adjustments.

This makes it suitable for applications requiring high positioning precision, such as:

Precision assembly

Trajectory-based operations

Speed Control

Finger motion speed can be flexibly adjusted according to task requirements.

High-speed mode improves operational efficiency

Low-speed mode ensures safe and precise manipulation

This enables the system to balance operational efficiency with safety, adapting to diverse task scenarios.

Tactile Feedback (Force Control)

 With fingertip sensors, the hand can detect and precisely control applied force and torque in real time.

The system dynamically adjusts output force to:

Prevent damage to fragile objects caused by excessive force

Avoid object slipping due to insufficient force

This provides reliable force control for delicate tasks such as:

Screw fastening

Thin sheet gripping

Precision manipulation

 Online Firmware Upgrade

The dexterous hand supports online firmware updates via a host computer.

This allows continuous upgrades of:

Functional modules

Core performance parameters

It is ideal for industrial and research scenarios requiring long-term iteration, ensuring the device remains efficient and up-to-date throughout its lifecycle.
