Mobile robot A robot system composed of sensors, remote manipulators, and automatically controlled mobile carriers. Mobile robots have mobile functions and are more mobile than general robots in terms of replacing humans in dangerous and harsh (such as radiation, poisonous, etc.) operations and in unmatched (such as space, underwater, etc.) environments. , flexibility.

According to the mobile node, it are often divided into wheeled mobile robot and crawler mobile robot; according to the working environment, it are often divided into the indoor mobile robot and outdoor mobile robot; according to the system structure, it are often divided into function Type (horizontal) structure robot, behavior type (vertical) structure robot and hybrid robot; according to function and purpose, it are often divided into a medical robot, military robot, handicapped robot, cleaning robot, etc.;
The crawler robot chassis is particularly used on special robots. it is the benefits of giant traction, tough to slip , and good off-road performance. It are often applied to the world and concrete environments and should advance various complex grounds, like sand and dirt . The speed is relatively low and thus the motion noise is large.

Wheeled robot chassis mainly includes front-wheel steering and rear-wheel differential drive, two-wheel drive + universal wheel, and four-wheel drive.
1. Front-wheel steering + rear-wheel drive
The front-wheel steering + rear-wheel-drive wheeled robot chassis mainly uses electric cylinders, worm gears, and other forms to know front-wheel steering. Only a motor plus a differential reducer on the rear wheels can complete the robot's movement requirements. it is the benefits and disadvantages of low cost and easy control, but the disadvantage is that the turning radius is large and thus the utilization is relatively inflexible.
2. Four-wheel drive
The four-wheel-drive features a robust ability to steer during a line , and thus the drive is relatively large, but the worth is simply too high, and thus the control is more complicated. so on stop the robot from slipping, a more elaborate structural design is required.

3. Two-wheel drive + universal wheel
The two-wheel-drive + universal wheel can arrange the universal wheel and thus the wheel in several forms according to the robot's requirements for the design center of gravity and turning radius. The structure and control are relatively simple, the robot is more flexible, and thus the algorithm is simple to manage .

Zhengzhou Difei mobile robot chassis manufacturer, the robot chassis produced are often used as a SWAT robot, a duct cleaning robot, and mini monitoring robot.
