rough surfaces. Each microspine end effector contains hundreds of steel hooks embedded in toe-like cartridges, which contact the surface and are pulled inward to grip the rock - not unlike the mechanics of a rock climber’s fingers while grabbing a climbing hold. The load applied to the end effector is shared across hundreds of

The RAT is a robotically controlled sci-ence instrument weighing less than 700 g (7 cm diame-ter, 10 cm long) and will be carried by the rover’s me-chanical arm. The primary purpose of the RAT is to remove dirt and rind from Mars surface targets (to 5 mm depth, 45 mm diameter) to reveal the underlying fresh rock features (Figures 1 & 2).
