This design of fire-fighting robot is based on infrared flame sensor and least-square method

which can accurately locate the fire and put out it. The hardware of the system is based on STC12C5 A

infrared flame sensor module and extinguishing module are added on the basis of the traditional robot. On software

use least-square method for curve fitting

get AD value and distance transformation model

then determine location of flame by comparing the data of sensors in different directions. Finally

move mechanical arm to the position of ignition

control spray pumps for fire-fighting. Experiments show that the system can run steady

has good versatility and promotion prospects.
