Richard A. Andersen, an expert on such systems at the California Institute of Technology in Pasadena who was not involved in the experiment, said that it was "an important advance to achieve locomotion with a brain machine interface".
"Using policies trained in simulation," the team writes in the paper, "the quadrupedal machine achieves locomotion skills that go beyond what had been achieved with prior methods: ANYmal is capable of precisely and energy-efficiently following high-level body velocity commands, running faster than before, and recovering from falling even in complex configurations".
In 1863, the photographer Nadar, famous for his panoramic pictures of Paris taken from a hot-air balloon, set up the Society for the Encouragement of Aerial Locomotion by Means of Machines Heavier than Air, which boasted Jules Verne among its members (the name of the hero in Verne's From the Earth to the Moon is an anagram of Nadar).
The joke implicit in Saramago's fiction is that he has placed his sober, mistrustful protagonists in a world of magic, where countries detach themselves from the mainland and float out to sea, cities are struck by epidemics of blindness and an 18th-century renegade priest escapes the Inquisition in a flying machine whose means of locomotion is the human will.
Pacific 231, Honegger's machine-age celebration of locomotion and steam, was bracing in its rawness and immediacy: nowadays we think of it as one of the iconic works of modernism, but it, too, was deemed "exotic", not to say outrageous, at its premiere in 1924.
Theo Jansen mechanism is gaining wide spread popularity among legged robotics researchers due to its scalable design, energy efficiency, low payload to machine load ratio, bio-inspired locomotion, deterministic foot trajectory among others.
Our approach, in combination with the growing collection of genetic tools available in Drosophila should open many additional opportunities to unravel the mechanism of locomotion in animals and improve bio-inspired machines.
There were simple engines, compound engines, triple-expansion engines and, perhaps the highlight of the rich collection of machines he garnered over several decades, George Stephenson's own, handbuilt model of Locomotion, the famous Stockton and Darlington railway locomotive that steamed, at speeds of up to 15mph, during the reign of William IV.
In the 2000 novel Wheelers, by English mathematician Ian Stewart and reproductive biologist Jack Cohen, an alien species called "blimps" has developed the ability to biologically produce machines called "wheelers", which use wheels for locomotion.
The machine's creators say the fish's unique locomotion could help it respond to underwater disasters similar to the 2010 Deepwater Horizon oil spill where aquatic robots had difficultly properly swimming into position to mend the leaking well.
