According to the mechanical structure, SCARA robot can be divided into multi-joint robot, planar multi-joint robot, parallel robot, rectangular robot, cylindrical robot and collaborative robot. Different types of industrial robots have different characteristics and application scenarios, which can be divided into the following categories:

1. Classification by mechanical structure:

Multi-joint robot: with multiple rotating joints, similar to a human arm, widely used.

SCARA robot: It has two parallel rotating joints and one vertical linear joint and is often used for assembly, handling and other tasks.

Parallel robots: Robots with multiple parallel rotating joints, often used for rapid take-up or product transfer applications.

Descartes robot: It has three prismatic joints that provide linear motion, suitable for tasks requiring high precision positioning.

Cylindrical coordinate robot: with an important rotatable joint and a prismatic joint, providing vertical and horizontal linear correlated motion development as well as rotational motion around the vertical axis, suitable for our simple pick and place work tasks.

Cooperative robots: Robots designed to interact with humans in shared Spaces or work safely nearby, suitable for automated repetitive, non-ergonomic tasks.

2. By application:

● Welding robot: Used for automatic welding tasks to improve production efficiency and welding quality.

* Handling robot: used to automatically handle materials, reduce manual labor intensity, improve production efficiency.

● Palletizing robot: Used for automatic palletizing tasks to improve palletizing speed and accuracy.

Packaging robots: Used for automated packaging tasks to improve the efficiency and accuracy of packaging.

● Spray robot: Used for automatic spray tasks to improve spray quality and efficiency.

● Cutting robot: used to achieve automatic cutting tasks, improve their cutting accuracy and efficiency.

Clean room robots: used to perform tasks in a dust-free environment to ensure a clean production environment.

Service robots: Advanced robots that provide essential services to humans in unstructured environments, including home service robots, medical service robots, and public service robots.

Special robots: Robots that replace humans in high-risk environments and special working conditions, including robots for military applications, extreme operations and emergency rescue. Robots with special structures, including a variety of custom, specially designed robots, such as snake robots (for pipe inspection and confined space operations), exoskeleton robots (for improving human capabilities), micro-robots (for microprocessing and medical applications), etc.

These are the main types of industrial robots, which can also be customized and combined according to specific needs and scenarios. In addition to the above types, there are some special industrial robots, such as drones, underwater robots, space robots, etc., which are often used for specific environments and tasks.

What are the differences between domestic robots and foreign robots in terms of functions, technologies and applications

In recent years, the robot industry has developed rapidly, and more and more enterprises have invested in the research and development and production of robot products. In this process, the competition between domestic robots and foreign robots is becoming increasingly fierce. Although there is a certain gap between domestic robots and foreign robots in terms of function, technology and application, this gap is gradually narrowing with the increase of domestic R&D investment, the promotion of technological innovation and the drive of market demand. In the future, domestic robots are expected to make greater progress in key technology breakthroughs, high-end application expansion, and international market competitiveness improvement.

When comparing domestic robots and foreign robots, our teachers can conduct in-depth investigation and analysis from three aspects of development: function, technology and application.

Functional differences

1. Accuracy: The accuracy of foreign robots is generally high, such as ABB, Kuka, FANUC and other brands of robots, the repeated positioning accuracy can reach ± 0.01mm, or even higher. The accuracy of household robots is relatively low, generally around ± 0.05mm. This is mainly because foreign enterprises have long-term accumulation and advantages in the research and development and manufacturing of robot core components.

2. Load capacity: The load capacity of foreign robots is generally strong, up to several tons or even dozens of tons. The load capacity of household robots is relatively weak, generally below 100kg. This is because foreign enterprises have a higher technical level in robot structure design and material selection.

3. Speed: Foreign robots move faster, generally reaching more than 1 meter per second. The speed of domestic robots is relatively slow, generally about 0.5 meters per second. This is mainly because foreign enterprises in the motor, reducer and other key components of the technology has a greater advantage.

4. Flexibility: Foreign robots have high flexibility and can achieve a variety of motion modes and path planning. However, the flexibility of domestic robots is relatively poor, mainly limited to simple linear and circular motion. This is mainly because foreign enterprises in the control system and programming technology more in-depth research.

The technical difference

1. Core components: Foreign robot enterprises usually have their own core components production lines, such as motors, reducers, controllers, etc. This gives them a big advantage in product performance and quality. Domestic robot companies often rely on imported parts, which limits the performance of domestic robots to a certain extent.

2. Control management system: The control information system engineering technology of foreign robot enterprises is more mature, and it can achieve economic, high-speed and high-precision motion control. However, the scientific and technological level of the control system of domestic robot enterprises is relatively backward, and the main work is manifested in the movement speed, accuracy and stability.

3. Programming technology: The programming technology of foreign robot enterprises is relatively advanced, which can realize complex path planning and motion control. The programming technology of domestic robot enterprises is relatively simple, mainly limited to basic linear and circular motion.

4. System integration: foreign robot enterprises have strong system integration ability, which can realize the integration application of various sensors and actuators. The ability of domestic robot enterprises in system integration is relatively weak, mainly reflected in the selection and application of sensors and actuators.
