RSSAmphibious snake-like robot "ACM-R5"
The creepy cool amphibious snake-like robot "ACM-R5" via jwz.
Sea snakes live in water, and even terrestrial snakes sometimes show swimming on water surface. In fact, the mechanism of snakes' propulsion is almost same both in water and on ground. An amphibious snake-like robot ACM-R5 takes advantage of this fact. It can operate both on ground and in water undulating its long body.The joint of ACM-R5 consists of an universal joint and bellows. It was developed on the basis of the previous model HELIX, which was designed for research of spirochete-like helical swimming. An universal joint plays a role of bones, and bellows do a role of an integument. ACM-R5 can form a smooth shape due to this joint structure, and it is important for effective locomotion. To be precise, the universal joint has one passive twist joint at the intersection point of two bending axis to prevent mechanical interference with bellows.
ACM-R5 is equipped with paddles and passive wheels around the body. To generate propulsive force by undulation, the robot need a resistance property as it glides freely in tangential direction but cannot in normal direction. Due to the paddles and passive wheels, ACM-R5 obtains that character both in water and on ground.
The control system of ACM-R5 is an advanced one. Each joint unit has CPU, battery, motors, so they can operate independently. Through communication lines each unit exchanges signals and automatically recognizes its number from the head, and how many units join the system. Thanks to this system operators can remove, add, and exchange units freely and they can operate ACM-R5 flexibly according to situations.

Fascinating. Although I'm getting horrifying visions of autonomous swarms of these things invading swimming pools around the world à la Matrix Sentinels...0_o

Not only that but the Japanese are about to bring "robot tentacle porn" one step closer to reality. Hide your Japanese School Girl on the day they mass produce this thing. As far as myself i want about 80 of these things about 4 meters long.

I for one welcome our future robot tentacle overlords.
And I too want a set of these things, I'd like to see them patrol my back yard and scare the raccoons away. Nothing else has worked...
