Humanoid robot rotary actuator technology combing
1.The principle of rotary actuator technology
A rotary actuator is a device that can convert electrical energy into mechanical energy and realize the rotational movement of mechanical components. Its core technologies include motors, reducers and sensors. As the core part of the rotating actuator, the motor can convert electrical energy into mechanical energy and realize the rotating movement of mechanical components. The reducer can reduce the motor speed and increase torque to meet the needs of various application scenarios. The sensor is used to monitor the position and speed of the actuator to achieve closed-loop control.
2.Application scenarios of rotary actuators
Rotary actuators are widely used in humanoid robots in various joints and driving components, such as the head, neck, waist, arms and legs. By using rotary actuators, humanoid robots can achieve various complex movements and movements, such as walking, bent over, grabbing and operating. In addition, the rotary actuator can also be used in other automation equipment and intelligent equipment, such as machine tools, automated production lines and drones.
3. Current development status of rotary actuators
With the continuous development of humanoid robot technology, rotary actuator technology is also constantly improving. At present, the rotary actuators on the market are mainly divided into two types: stepper motors and servo motors. The stepper motor achieves precise positioning by controlling the number of pulses, but its torque is small and suitable for small load scenarios. The servo motor has high torque and high accuracy, and is suitable for scenarios where large loads and high stability are required. In addition, there are some emerging motor types, such as brushless DC motors and switched reluctance motors, which have higher performance indicators and wider application prospects.
4. Future trends of rotary actuators
With the continuous advancement of technology and the continuous improvement of application requirements, rotary actuator technology will continue to develop. In the future, rotary actuators will move towards higher torque, smaller volume, longer life and lower costs. In addition, with the development of sensors and intelligent control technologies, the degree of intelligence and autonomy of rotary actuators will also be improved. This will bring more possibilities to the development of humanoid robots and other automation equipment.
5. How to choose the right rotary actuator
When choosing the right rotary actuator, we need to consider the following factors: torque, speed, size and weight, life and reliability, cost, etc. Depending on the application scenario and requirements, choosing different types of motors and reducers combinations is also an important factor that needs to be considered. For example, in the leg joints of humanoid robots, larger torque and smaller volume are required, so a servo motor can be selected with a harmonic reducer or RV reducer; while in hand grabbing or operating, higher needs to be required The accuracy and faster response speed can be selected, so stepper motors can be combined with harmonic reducers or planetary reducers.In short, as one of the core components of humanoid robots, the development and application of its technology play a crucial role in the performance and stability of humanoid robots. In the future, with the continuous advancement of technology and the continuous increase in application demand, rotary actuator technology will continue to develop, bringing more possibilities to the development of humanoid robots and other automation equipment.
