I read about a time when all products, electronics in particular, had to be designed to withstand a 30 foot drop and continue to operate. This bot, along with the Dragon Runner military bot can handle that, no issue.
I always try to over-build my designs. Rugged and simple is my design philosophy.
Another great use for a robot. As for the time it takes, having done a number of government projects, you have to find Mil grade components and go through a whole series of "mother may I's" before you get it built and then run it successfully through all of the acceptance tests. Sometimes, throwing money at the problem does not speed the build and test process.
Anyway, I am glad that they have a working model, now they can replicate them as needed and that is the important part of the cycle.
