Wheeled explosion-proof chassis is a modular mobile platform with stable functions and flexible and fast movement. The car body adopts explosion-proof design and independent suspension to enhance the passability and load capacity of the car body. The body is driven by four-wheel independent servo motors, and differential steering can ensure a smaller turning radius. Adding modular equipment to the car body can make it meet many fields such as inspection, transportation, security, agriculture, forestry, industry, etc., and can even be flexibly converted into an automatic disinfection platform.
