Drones, UAVs, UUVs, and small robotics require increasingly more demanding performance and superior SWaP (Size, Weight, and Power) advantages.  COM Express is small and rugged, with a wealth of mezzanine-based modules in various size/performance options.  MicroTCA and 3U CompactPCI and CompactPCI Serial are also small and offer high-performance and versatility of options.  With the small size of AMCs (Advanced Mezzanine Cards) in MicroTCA, one can utilize a versatile backplane approach in a small, light, and powerful form factor.   There are also highly ruggedized implementations of these specifications.

One of the most famous unmanned robots uses CompactPCI technology — The Mars Rover.  The system was only expected by NASA to last a few months in Mars’ harsh environment.  The computer is still send data today, over 13 years later!
