When robot labs create a range of movements for their robot, they are often mimicking animals. I'm fascinated by how good these machines are getting. They are now solving problems like stairs and opening doors.

Boston Dynamics is top dog at present.

Spot Mini appears to be a dog crossed with an emu at times.

Cross between a human body and a donkey, I think.

This robot and animated drawing show the range of movements available to early land walking creatures.

Boston Dynamics again.

Their 'Spot Mini' robot harnessed as a dog team to mush a truck.

Paro is a baby seal robot. To give elderly people something to look after like a pet, which is responsive.
Personally I'd rather fill a bird feeder.

" With the government unveiling the UK's first official robotics strategy last week, which could lead to an increased use of robots in our everyday lives, Amanda Sharkey, a senior lecturer in Sheffield University's department of computer science, warns: "I think we need to be a bit careful about human interactions with robots, so we don't end up with old people being looked after by robots and nothing else. So I think you could misuse Paro in the sense of: we've given this old lady the seal to look after and now we don't have to go and talk to her." "

Here is the YT film.

An eel has inspired this undersea mechanic robot.

Extremely interesting roundup of ten robots; look out for the dragonfly and butterfly, the fish and shark, among others.

The pigeon bot. And it flies.

"Takikawa, located on Japan’s northernmost island of Hokkaido and home to about 41,300 people. The robot, appropriately dubbed Monster Wolf, was installed to scare off wildlife—mainly bears—to stop them from getting near residential areas."

Has to be seen to be believed. Scary, bigtime. But harmless.

"Researchers are interested in developing devices that can navigate these situations by sniffing out chemicals in the air to locate disaster survivors, gas leaks, explosives and more. But most sensors created by people are not sensitive or fast enough to be able to find and process specific smells while flying through the patchy odor plumes these sources create.

Now a team led by the University of Washington has developed Smellicopter: an autonomous drone that uses a live antenna from a moth to navigate toward smells. Smellicopter can also sense and avoid obstacles as it travels through the air. The team published these results Oct. 1 in the journal IOP Bioinspiration & Biomimetics.

"Nature really blows our human-made odor sensors out of the water," said lead author Melanie Anderson, a UW doctoral student in mechanical engineering. "By using an actual moth antenna with Smellicopter, we're able to get the best of both worlds: the sensitivity of a biological organism on a robotic platform where we can control its motion.""

"“Soft-bodied organisms living at medium ocean depths [of more than 1,000m] such as octopuses and jellyfish, have been widely studied; their adaptability has inspired the design of underwater soft robots. Elegant soft robot designs present promising approaches to deep-sea exploration,” the paper – "Self-powered soft robot in the Mariana Trench" – said."

These are 3D printed shells of fossil sea creatures.

"the scientists who are, through a range of methods including digital models and 3D printed replicas, "de-fossilizing" animals of the past to learn how they lived.

Peterman, Ritterbush and their colleagues took 3D printed reconstructions of fossil cephalopods to actual water tanks (including a University of Utah swimming pool) to see how their shell structure may have been tied to their movement and lifestyle. Their research is published in PeerJ and in an upcoming memorial volume to the late paleontologist William Cobban. They found that cephalopods with straight shells called orthocones likely lived a vertical life, jetting up and down to catch food and evade predators. Others with spiral shells, called torticones, added a gentle spin to their vertical motions.

"Thanks to these novel techniques," says Peterman, a postdoctoral scholar in the Department of Geology and Geophysics, "we can trudge into a largely unexplored frontier in paleobiology. Through detailed modeling, these techniques help paint a clearer picture of the capabilities of these ecologically significant animals while they were alive.""

Got to love geckoes.
Here, observation in rainforests combines with a soft robot built to mimic gecko landings in the lab. See the clip.

Robot fish can pick up microplastics.
Interesting explanation of oystershell.

"the traditional materials used for soft robots are hydrogels and elastomers, and they can be damaged easily in aquatic environments. Another material called mother-of-pearl, also known as nacre, is strong and flexible, and is found on the inside surface of clam shells. Nacre layers have a microscopic gradient, going from one side with lots of calcium carbonate mineral-polymer composites to the other side with mostly a silk protein filler. Inspired by this natural substance, Xinxing Zhang and colleagues wanted to try a similar type of gradient structure to create a durable and bendable material for soft robots."
