Cyro – Large Robot Jellyfish

A robotic jellyfish. Go figure.

Cyro is a human-sized jellyfish robot developed by team of researchers at Virginia Tech College of Engineering, headed by Shashank Priya. They modeled it on one of the world’s largest jellyfish, Cyanea capillata (AKA lion’s mane jellyfish). Cyro is a larger version of Virginia Tech’s human hand sized RoboJelly.

“Jellyfish make great models for self-powered and autonomous bots partly because of their relatively low metabolic rate, meaning they can move through the sea on little energy. They also come in various sizes and inhabit a range of aquatic habitats from shallow coastal areas to the deep-sea, meaning engineers have plenty to work with when looking for a mimic for particular uses” (source: LiveScience).

Specifications:

Weight
170 lbs. (77 kg)
Length
5.6 ft. (1.7 m)
Operating Environment
Oceans
Function Prototype for self-powered, autonomous robots that monitor the seas, map the seafloor and even reveal secrets of marine life
Development Stage Second generation prototype developed at the university level.
Unique Features SubmersibleVertical lift: moves from 8-feet-deep (2.4 m) to the surface with five complete pulsing motions.

Cyro uses an upward swimming motion for propulsion. Linear actuators move radially from an outward position in toward the center that create pulsing motions of the artificial mesoglea, or the gelatinous substance that makes up the jellyfish’s skin.

Jumping Robot

SandFlea“Soldier, I want you to take this video camera, jump onto the roof that building, take images of the enemy, and come back.  Oh, and they’ll be shooting at you.”

“Or you can use the SandFlea.”

The SandFlea looks like the RC car most kids would love to play with because, in addition to cruising around the yard, it can jump 30 feet into the air, high enough to clear a wall, on to a roof of a house, up the stairs, or though a second story window.  An onboard stabilization system keeps it oriented during flight to improve the view from the video uplink and to control landings.

Sand Flea is funded by the US Army’s Rapid Equipping Force and scheduled to undergo safety and reliability checks at the Army Test and Evaluation Command (ATEC).  If it passes evaluation, several will be field tested in Afghanistan, where US military currently uses more than 2,000 robots.
