Robots Walk With Close-To-Human Efficiency
ScienceDaily (Feb. 23, 2005) — WASHINGTON, D.C. -- Robots that walk like human beings are
common in science fiction but notso easy to make in real life. The most famous current example,
the Honda Asimo, moves smoothly but on large, flat feet. And compared with a person, it consumes
much moreenergy.
"Already our robot
seems to be at least 10
times more efficient than
anybody else's," says
Andy Ruina, Cornell
professor of theoretical
and appliedmechanics.
The Cornell robot consumes an amount of energy per unit weight and distance comparable to a
human walker. In contrast, they estimate that the Honda Asimo uses atleast 10 times as much
energy as a human. The MIT and Delft robots, though not built deliberately to be energy-efficient,
also use much less energy than the Asimo. Moreimportant, the researchers say, is that their robots
provide a more realistic model of how humans walk.

“Passive dynamic walkers such as the Cornell Efficient Biped have the same specific cost of
transport as humans, 0.20. Not incidentally, passive dynamicwalkers have human-like gaits. By
comparison, Honda's biped ASIMO, which does not utilize the passive dynamics of its own limbs,
has a specific cost of transport of3.23."

Why do humans walk on two legs? To save energy
The study found that humans used about 75 percent less energy thanwalking on all fours or two
legs for chimpanzees, according to the report.
