This is, as you might have guessed, a robotic leg, one currently in development by engineers
00:08
at ETH Zurich and the Max Planck Institute for Intelligence Systems. However, it's not using
00:14
actuators, cogs, or other conventional robotics to move, but rather artificial muscles. The
00:19
researchers are calling them electrohydraulics, which use oil-filled plastic bags with conductive
00:23
electrodes on either side. Here's one of the researchers, Thomas Buckner, to explain.
00:28
And now, when we activate these muscles, the so-called electrohydraulic actuator sips together,
00:34
which means the electrodes come closer and push the oil to the other side of the actuator.
00:41
This leads to a contraction and thickening of the muscle, similar to a human muscle.
00:46
They add that this type of system also has an antagonistic pairing, similar to the bicep
00:51
and tricep in your arm.
00:52
They work against each other. If the biceps contracts, the tricep stretches, and the other
00:57
way around the bicep stretches when the triceps contract.
01:00
Which they say means the system becomes much more energy efficient and more nimble than
01:04
traditional motor-driven robotics. This type of robot is also more adaptive to uneven terrain,
01:10
letting it respond without the need for sensors to constantly apply corrections to its movement,
01:14
with the team adding that this could one day be used for rescue operations in areas inhospitable
01:19
for human rescuers.
01:20
For human rescuers.
01:21
For human rescuers.
