Abstract: ZXPJ01 fire-fighting robot is a multi-function teleoperator, which integrated detection in the scene of a fire and where there are venomous, flammable and explosive gas, and fire fighting, and so forth. This paper presents the system structure, working principle, the realization of the explosion and thermal protection of electronic equipment, and the control system including hardware and software. The prototype of the robot has been realized; experiments demonstrate the reliability of the system and all performance indexes are satisfied with the designed requirements.
