Mobile robots are a type of robots that can move independently, with the following main characteristics:

1. Autonomous movement: The mobile robot is equipped with a wheeled or tracked drive system, which can move independently in the working environment and does not need to be installed on a fixed track or position.

2. Action Autonomy: Mobile robots are usually equipped with computer control systems and various sensors, and can perceive the path and direction of autonomous decision-making action based on the environment.

3. Flexible tasks: Mobile robots can perform various mobile operation tasks, such as patrol monitoring, logistics and transportation, cleaning and salvage, etc., and the task types are relatively flexible and changeable.

4. Strong environmental adaptability: Mobile robots need to adapt to various complex working environments, such as terrain, construction sites, etc., and have strong environmental adaptability.

5. Possible collaborative operations: Multiple mobile robots can form networks to work together, such as logistics distribution, assembly structure, etc., to achieve group collaboration of robots.

6. Communication networking: Mobile robots usually use wireless communication, and realize real-time data exchange and command issuance with the main control system, and direct communication can also be achieved between some robots.

According to the different modes of movement, mobile robots can be divided into:

1. Wheeled mobile robot: Use tires or elastic wheels as driving devices, with high maneuverability and simple mechanism.

2. Crawler-type mobile robot: uses crawler chains as driving device, which are highly adaptable and have a large load.

3. Combining wheel and footwear with mobile robots: both tires and tracks are used, with both mobility and adaptability.

4. Bipedal mobile robot: simulates the bipedal walking method of humans or animals, with strong adaptability and flexibility.

5. Four-legged/hexagonal mobile robot: four-legged or hexagonal bounce drive, with strong resistance and load.

Mobile robots have a wide range of application prospects, especially with the development of artificial intelligence and 5G communication technology, the intelligence level and collaborative operation capabilities of mobile robots will be greatly improved. In the future, we can expect to achieve more autonomous and efficient in more complex environments. operation and homework.
