Hydraulic wrist: the source of dexterity for future robotic arms

With the rapid development of technology, robot technology has penetrated into every aspect of our lives. From industrial production to medical rehabilitation, and then to deep-sea exploration, robots are everywhere. In these applications, as an important component of robots, the flexibility and accuracy of robotic arms directly affect the efficiency and practicality of robots. As a key component of a robotic arm, hydraulic wrists are gradually receiving widespread attention from the industry for their unique performance and design.
1、 The working principle of hydraulic wrist
Hydraulic wrist is a mechanical device that drives multiple joints through a hydraulic system to achieve complex movements. It utilizes the flow of liquid (usually oil) in a closed pipeline to transmit force and motion, thereby achieving movements such as wrist rotation, bending, and extension. Compared with traditional electric or pneumatic wrists, hydraulic wrists have higher load-bearing capacity and better stability, and can operate stably for long periods of time in harsh working environments.
2、 The advantages of hydraulic wrists
1. High precision control: The hydraulic wrist adopts a high-precision hydraulic control system, which can achieve small motion adjustments and precise force control, making the robotic arm more advantageous in fine operation.
2. High load-bearing capacity: The hydraulic wrist can withstand large loads, allowing the robotic arm to maintain stability and accuracy during heavy load operations.
3. Good adaptability: The hydraulic system has good adaptability and can adjust wrist movements and force output according to different working environments and task requirements.
4. High safety: Hydraulic wrists have lower safety during operation
