Mechanisms of Curiosity's drill
The drill bit assembly is a non-motorized drill, sleeve, and sample chamber. It can be swapped with two other drill bit assemblies carried in bit boxes on the rover. The drill chuck mechanism is used to exchange drill bit assemblies. The drill spindle, percussion, and feed mechanisms are required for drilling. The drill contact sensors/stabilizers press against the ground, holding the turret steady as the drill operates.
