Scientists have often observed animals using an "announcement" call before beginning their true message. There are often introductory notes in territorial calls in bird species; frog mating calls begin with a low frequency ribbit, and coyotes often bark before they begin their characteristic howling. However, it is the case that the message is not ALWAYS preceded by the announcement. So when do animals use the announcement, and when do they just launch into their speech? It should be noted that it can be very dangerous for animals to use the announcement - whether visual or auditory - because it could also signal predators that lunch is ready. Like a visual dinner bell. (There's a species of bat that is really really sensitive to the mating call of a species of frog. Bad news for the male frogs when they're ready to get it on.) Research supervisor Dr. Christofer Clemente said there was potential for lizard-inspired robots to assist with communications, search and rescue, and remote inspections (for example telephone poles).

The robot had 100 per cent success at staying on the wall when its forelimbs were rotated outwards 20 degrees and its hind limbs 100 degrees. It also held fast to the wall when its limbs were rotated inwards at the same angles.

Mimicking years of evolution to make climbing robots

The team then built a robot model to investigate the advantages of lizardlike and snakelike body movements in the intermediate lizard species. Known as a robophysical model, the robot functions as a physicist’s model of a living system that can also be used to vary parameters such as limb length and how the lizard’s body drags on the ground. With such capabilities, they can test the predictions of their theoretical model while also gaining understanding of the biological system. Overall, the team observed that the degree of body elongation and limb reduction in lizards is directly related to how body and limb movements are coordinated, indicating a closely intertwined continuum between body shapes and locomotion style. The researchers even found the tiny limbs to be of significant use to the lizards, not only with propulsion, but also with lifting their bellies off the ground.

Known as a robophysical model, the robot functions as a physicist’s model of a living system. With the robot, they can test the predictions of their theoretical model while also gaining insights into the intermediate lizard’s biology and locomotion. The researchers then repeated the experiment with a species from the mainland (Microlophus occipitalis) and found that this species very much discriminated against displays made by different species of lizards.

Have you ever been walking through the forest and thought to yourself, "Damn, its loud here...it's really, really hard to hear anything anybody else is saying"? Well, maybe that's what prompted Terry J. Ord and Judy A. Stamps, respectively from Harvard and UC Davis to investigate lizard exercise routines. Over time, as these differences between the two different populations become larger and there is less and less mating between the populations, they will become ‘reproductively isolated’ (i.e. not mating with each other at all) and thus become two new species. Robot lizard. Not only could their robot lizards do push-ups, they could display their dewlaps! See videos of robot push-ups and dewlaps. One set of animals where it is not clear how the differences between similar species arose is the lava lizard. Lava lizards live throughout the Galapagos archipelago and there are nine species in total. The different species are separated from each other geographically and have both different colouration and different push-up and head-bob behaviour that they use for communication.Funding:NSF–Simons Southeast Center for Mathematics and Biology (Simons Foundation Autism Research Initiative Grant 594594), NSF Grant IOS-1353703, President’s Undergraduate Research Awards at Georgia Institute of Technology, and Army Research Office Grant W911NF-11-1-0514. Using geometric mechanics, Chong produced diagrams that visualized the body-limb coordination data, replacing complicated calculations with much simpler diagrammatic analysis. They were able to both see and show the advantage of snakelike waves in short-limbed elongate lizard locomotion and predict that the advantage arises as the primary thrust generation shifts from the limbs to the body. This fantastic kit has everything necessary to build your loveable reptilian, giving you the satisfaction of building your very own AI robot. This kit is a great project for adults and children alike, allowing you to create, build and play. The researchers’ findings enabled them to conclude that evolution was not just acting to lengthen bodies or shorten limbs, but both — and in a highly coordinated and functional way. The biomimetic robot created by Chen and his colleagues is comprised of a flexible spine-like structure and four legs. To replicate the "creeping" motion typical of lizards, every leg features two hinges and a gear that elicits a swinging movement.
