Due to the frequent occurrence of accidents caused by loose manhole covers or stepping on them, manual rescue is difficult and dangerous for rescuers themselves. Therefore, we have designed a rescue robot that can be used for life detection, light detection, photography and video recording, voice broadcasting, safety grip, and safety belt wrapping under the armpit. It can also be used for remote rescue outside the well and is suitable for rescuing wells of different diameters. This improves the ability to respond to different diameter well rescues and reduces safety accidents.Firstly, the robot can be controlled to dive using a remote control; then the hydraulic tripod telescopic arm makes the roller skate tire closely attached to the well wall for diving; finally, the safety belt can be wrapped around the armpit or the safety claw can be lowered for clamping. This can achieve simple rescue work.
