The shotcrete robot was a model of robot used in mining. Its purpose was to line and thereby reinforce a mineshaft with a quick–drying mortar dubbed shotcrete; the name derived from the robot's method of delivery, which involved firing the material at pertinent areas. It was spherical in shape, and could be used in conjunction with a drill bit. Shotcrete robots were used at the Svarog Mine on the Union of Progressive Peoples mining planet Shānmén.
