Matt Denton of Micromagic Systems built this Mantis hexapod robot powered by hydraulics:
After four years intensive R&D, inspiration, design and build, Micromagic Systems is proud to unveil Mantis — the biggest, all-terrain operational hexapod robot in the world.
This 2.2-litre Turbo Diesel-powered, British-designed and -built walking machine can be piloted or remote WiFi-controlled, stands 2.8 metres high with a five meter working envelope and weighing in at just under two tonnes.

Google “plusjack walking harvester” to see similar device from early 90’s.
I admit it’s got a very high “cool” factor. I’m trying to imagine what the real applications would be and having some trouble. Wheeled and tracked vehicles are easier to make and operate, and they can cover some very rough terrain.
Useless without rocket launchers…
This is similar than this old Finnish forrest harvester done at 1994. Here is old video about this machine: . That machine was controlled using networked transputer processors. In that time those were state of the art of real time movement controllers. The control program was made using Occam code, which is special programming language mainly intended for parallel programming.
