Musk announced that Tesla will produce humanoid robots on a small scale in 2015 for Tesla's internal use, and is expected to mass produce them in 2026 for use by other companies. Millet company also announced the development of millet robot, cyberdog quadruped bionic intelligent robot dog. A large number of domestic and foreignarticulated robotThe manufacturing boom of bionic robots has also brought a number of manufacturers and industrial chains of joint modules, axial flux motors, magnetic encoders and SMC soft magnetic composite materials.
articulated robotIs it the same structure as humans?
Humans and robots have something in common. Robots and humans appear to be distant entities, but in fact they have the same bone and joint structure. Industrial robots are mainly composed of mechanical arms, and their basic structure is a combination of links (bones) and joints. In the human body, the elbow, shoulder and other parts that can bend freely are joints, and the bones that connect them are called links. The principle of moving joints and transmitting forces through links is the same for humans and robots. According to the movement mode and structure of links and joints, industrial robots are divided into many types such as "vertical multi-joint type" and "horizontal multi-joint (SCARA) type.
The vertical multi-joint robot is an industrial robot with a serial linkage mechanism. It is generally composed of six joints (six axes).
The first axis to the third axis is the waist and arms, and the fourth axis to the sixth axis is from the wrist. The first three axes carry the wrist to a specific position. The next three axes allow the wrist to move in any direction. This kind The 6-axis configuration allows it to move freely like a human.

What is needed to support the robot's joint activities?
The answer is: actuators, reducers, encoders, conduction mechanisms, etc.
What kind of mechanism is the actuator of the joint robot?
First, let's explain the basics of actuators.
Actuators convert power into mechanical motion. Actuators are mechanisms that convert power into mechanical motion. For example, the motor is one of them. By using the actuator, the robot can freely adjust the force, speed and movement angle.
Actuators are ubiquitous in daily life. Actuators are also used to open and close automatic doors, car wipers, and game consoles in amusement facilities. Actuators are indispensable not only in everyday machinery, but also in places where the latest technology is used, such as linear motor cars, astronomical telescopes and medical equipment. It is no exaggeration to say that developing actuators is directly related to changing people's lives.
What motors and reducers are used in the actuators of joint robots?
Generally speaking, the motor and reducer combination installation. By combining the motor and the reducer, the power of the motor is extracted.
Generally, there are three types of motors installed in joint robots: brushless DC motors, stepper motors, and servo motors. These three types of motors have radial motors and axial flux motors (disc motors) depending on the design and mode of action. No matter which kind of drive is inseparable from rare earth permanent magnets (neodymium iron boron). Motors wearing rare earth permanent magnets have high-speed and high-precision positioning, maintain high torque, low noise and vibration, stable rotation, and of course, material costs High and expensive are also their shortcomings.
What activities can these articulated robots replace humans in?
The work that these articulated robots have done so far to replace humans can be roughly divided into six categories:
Articulated robots are not only used in the automotive industry, but also in a wide range of fields such as the electronic/electrical industry and the food industry. At each site, they are used in a variety of ways, including welding, painting, assembly, sorting and transportation, and there are a variety of products that can meet these tasks.
The future of articulated robots
With the development of society,The joint robot has broad development prospects and can be widely used in factories, logistics, rescue, medical treatment, education, scientific research, entertainment, service and other scenes. Articulated robots also gradually have the basic characteristics of human beings, such as head, eyes, hands, legs, etc., which help to interact with humans more naturally and intuitively, and enhance the affinity and communication effect between man and machine. Humanoid robots are designed to imitate human movements and postures such as walking, grasping, and expressions to provide a more realistic experience.

What can articulated robots bring us?
The joint robot is a bionic human with a serial linkage mechanism, which is generally composed of six joints. When the function and axis of the 6-axis vertical multi-joint robot correspond to the human body, arm, wrist and hand, they can make similar actions to human beings. This is also the biggest reason why the robot has become the mainstream.
With the development of automobile industry, permanent magnet sensor is more and more used in automobile manufacturing industry. The permanent magnets used in permanent magnet sensors are usually ferrite, neodymium iron boron magnets, and samarium cobalt permanent magnets. They have different shapes and are usually used to monitor the angle, stroke, position, speed, etc.
The camera three-rotation rod is an accessory used for photography or video cameras to achieve three-dimensional rotation of the camera. It is usually composed of three rotating rods, namely, pitch rotating rod, roll rotating rod and azimuth rotating rod. The pitch rotation bar is one of the most basic rotation bars in the camera's three rotation bars. It allows the camera to rotate in the vertical direction, thereby changing the shooting angle of the camera. By adjusting the pitch rotation bar, the photographer can tilt the camera up or down to capture photos at different angles and perspectives. This is useful for shooting scenes such as landscapes, buildings or people.

SMC outer stator core is a new type of motor stator core material
SMC outer stator core is a new type of motor stator core material, which is composed of epoxy resin and glass fiber. It has excellent insulation performance and high strength, which can effectively reduce the volume and weight of the motor. The SMC outer stator core has good heat resistance and corrosion resistance, and can maintain stable performance in harsh working environments. In addition, its manufacturing cost is relatively low and its production efficiency is high. The SMC outer stator core also has excellent magnetic permeability and low magnetic loss, which can improve the efficiency and power density of the motor. Therefore, the SMC outer stator core is widely used in various motors and transformers, especially for occasions with high requirements on volume and weight, such as electric vehicles, wind turbines, etc. In short, the SMC outer stator core has excellent performance and economy, and it is one of the important directions of future motor development.
