  • The general goal of our lab is to understand the

  • locomotion aspect of animals. Recently we are focusing

  • on quadrupeds, or four-legged animals and we try to

  • understand how they efficiently run in the field and nature

  • so that we can take that inspiration and then use it

  • in our engineering world. So for example we can create

  • prosthetic legs out of that technology and you could even

  • make new transportation replacing cars so that you

  • don't need the road in our world.

  • The cheetah is the fastest four-legged animal in the world

  • and we would like to make out robot run fast like a

  • cheetah.

  • When we started with our robot, we started to look at

  • cheetahs' motion and applied its principles to our

  • mechanical version of a cheetah.

  • Currently our robot cheetah can run up to 10 mph and

  • jump over a 33 cm high obstacle. So previously, most

  • legged robots are powered by internal combustion

  • engines and then hydraulic transmissions, and those are

  • very noisy and very inefficient. But people believe that

  • internal combustion engines and hydraulics are the only

  • way to make a legged robot run and support itself.

  • People believe that electric motors are not powerful

  • enough, so this is the first time we show that an

  • electrically powered robot can run and jump over

  • a foot high obstacle. In order to build a dynamic robot like

  • Cheetah we had to develop everything on the robot

  • including motors, control system and control algorithms.

  • Because previous robotic technology is focused on

  • controlling static motion over the robot.

  • I think this is a really exciting future where robots can be

  • quiet and efficient and also powerful and then we might

  • exceed the muscles' performance in the future.
