Inspection robots are suitable for areas with dense equipment, such as substations, chemical plants, semiconductor factories, data centers, etc. By carrying different sensors, surveys can be carried out with designated instruments. For example: use thermal imaging cameras to detect power generation, batteries, motors and other equipment to see if there is a risk of overheating; use gas detectors in semiconductor factories and chemical plants to detect whether toxic substances leak accidents; use high-magnification cameras Interpret various digital analog instruments; judge whether there is an abnormality in the instrument by acoustically collecting the noise at each frequency of the equipment; or use a high-payload drone to clean high-altitude insulation barriers, etc.
