Can you tell what this robot does just by looking at it? If not, that is exactly why standards are needed—to prove what the robot can do. This particular method tests the robot’s ability to inspect, touch, rotate and extract items.

Fully resolved features include the graphitic lattice and interlayer wall spacing, CNT diameter, CNT spacing and vertical corrugations. (Image by Ryan Chen/LLNL)
