INSPC 23 is an autonomous mine inspection tool, which analyses the bolt and rock condition in a mine, for a safer working environment. With the help of a monitoring module it checks the previous installed rockbolts (the installing of rockbolts is dirty and a lot of pressure is on the machines). If there is a need, the inspection tool can also install little sensors. When the rock is moving, the sensor will give an alert and points out the danger zone with red light. In a coal mine the inspection tool can check the CO2 content in the air. In case of to much CO2 it alerts with blue lights. The tool can also provide more light for the miner in the working area.
