Robots move autonomously, positioning and navigation are key. At present, more and more companies produce robot chassis, which can help robot companies reduce research and development costs and quickly seize market opportunities. The chassis integrates many different sensors, including lidar, vision, ultrasonic, infrared sensors, etc., and the necessary suspensions such as wheels. So, how many types of chassis are there?
1. Tracked
The tracked robot chassis is used more on special robots, and can be applied to the field and urban environment. It can move on various complex grounds, such as sand and mud.
2. Wheeled
The wheeled robot chassis is currently used by service robot companies. It mainly includes front-steering rear-wheel differential drive, two-wheel drive + universal wheel, and four-wheel drive.
3. Four-wheel drive
Four-wheel drive has a strong ability to travel in a straight line, and its driving force is relatively large, but the cost is too high and the motor control is more complicated. In order to prevent the robot from slipping, a more detailed structural design is required.
