the worm is essentially able to send "waves of fatness" running from its nose to its tail. These waves, along with dirt-gripping bristles called setae, allow the animal to tunnel through the soil.

Earthworms are smooth-skinned worms with a tube-within-a-tube segmented body plan. Each segment is covered with a row of bristles called setae. These bristles anchor them on the ground and are the ...

At about 1.5 feet (45 centimeters) long, the prototype earthworm robot has five PSA segments covered with tiny bristles called setae, also found in living earthworms. While these bristles and ...

Alongside a paper published in the journal Cyborg and Bionic Systems, the team also released footage of the robot in action.

In order to propel the robot on a planar surface, small passive friction pads inspired by earthworms' setae were attached to the ventral surface of the robot. The robot demonstrated improved ...

There have been innovations in mimicking earthworm setae (bristles), which help worms to anchor. Plus, there's been progress copying the fluid in their segments which, among other functions ...

The robot is also outfitted with small passive friction pads inspired by earthworm setae to propel itself on a planar surface. With a speed of 1.35mm/s, the robot showed enhanced locomotion.

different-colored band on the worm’s body — and setae, the tiny bristles lining the body that help the worm move. Another difference is that non-native and native worms prefer holing up in ...

IIT researchers have studied the morphology of earthworms and have found a way to mimic their muscle movements, their constant volume coelomic chambers and the function of their bristle-like hairs ...
