There are a few ways of looking at the WildCat robot designed and tested by Boston Dynamics, one is that it could be a really useful tool for transported much needed supplies to unsafe areas such as those affected by natural disasters etc.
The other is that it will be adopted by the military, armed to the teeth and let loose, where it will become aware and realise that the human race is the enemy! We know the rest of the story as the machines start giving themselves numbers preceded by a T!
The WildCat being tested here was able to reach speeds of 16 mph on an even surface, it is quite fast on rough terrain too and as such a robot like this one can do a lot of good in the right situations.
