When you see a Sinjab jumping into a branch, you may think (and I have thought, yet) that they are doing what birds and lines will do to fix the landing: just seizing the branch and hanging. But it became clear SquirrelBeing a squirrel, you do not actually have hands or prior feet, which means that they cannot understand things with any great strength. Instead, they managed to land on the branches using an understanding of “Palmar”, which does not matter at all, meaning that there is not much seizure. It is accurate to say that the squirrel often falls into the comfort of his hand and then balance, which is very impressive.
This type of dynamic stability is a feature in which squirrels share with one of our favorite robots: salto. Salto is also the birdIt is not insulting as much as it can be obtained, with only one party with no fist force at all. The robot is great in the bounce on the ground, but if it can move vertically, this after a fully new transportation can lead to some applications that are likely to be interesting, including environmental scout, Search and rescueAnd Disaster relief.
in A paper published today in Science robotsAl -Alaion has now taught salto jumping from one branch to another like squirrels, using low torque clutch And relying on balance skills instead.
Singering decline techniques in Robots
While we will mostly talk about robots here (because this is what we do), there Full paper By many of the same robotics researchers in late February in Experimental Biology Magazine About how the squirrels fall on the branches in this way. WHILE believed that researchers may have found some domesticated squirrels for this purpose. They actually spent about a month in the bribery of wild sinness on Uc Berkeleg The campus for apostasy around some of the instruments of the instrument while high speed Cameras They were trading.
Sinbids aim to completely balanced landing, which allows them to jump again immediately. They do not always get it properly, of course, and they are excellent in recovering from a sub -drop as they go a little or under the place they want to be. The research showed how crabs use its musculoskeletal system to adjust its position in the body, and to absorb a dynamically impact of the decline with its front and change its collective distribution to convert proximity to successful wheels.
These types of skills SALTO really need to be able to achieve jumps in the real world. When everything goes exactly the way it is assumed, jumping and wandering is easy, but this never happens, and Single research shows how important you are able to adapt when things become increasing. It is not as if the small robot has a lot of freedom at work – it has only one leg, only one feet, and two defenses, and this is the spinning ingredient that is believed, not believed or does not work as a tail. However, Salto enables (sometimes!) It makes it work.

These balanced, highly impressive rectal landing, although we must mention that Salto has achieved this level of success with two out of 30 experiences. It actually fell only on the body of five times, and the rest of the time, it ran the landing, but then it did not balance it completely or either surpassed the branch. There are some mechanical reasons that make this particular difficult on Salto-for example, that only one leg to use it in both jumping and landing means that the robot stem must be rotated in the middle of jumping. This takes time, and leads to jumping vertically more than squirrels, because the squirrel jumps with their back legs and the ground with their front legs.
Based on these tests, the researchers have set four main features of the balanced decline that apply to robots (and Sinjab):
- Power and accuracy are important!
- It is easier to land in a shallow leap with a more horizontal path.
- Be able to enjoy near the branch helps in the budget.
- It is also important to run the response!
Among them, Salto is great in the first, not great in the second, and also not great in the third and fourth. Therefore, it is surprising that the alain has to get this jump from the branch to the branch as well as they have. There is a lot to do, though. Sinbids are not the only tree players there, and more animals are likely to learn –Salto was originally inspired by GalaGo (Also known as as Bush children) Although it is difficult to find on the campus of the University of California in Berkeley. Although researchers do not mention this, the apparent extension of this work is a series of multiple jumps, and in the end the combination of sub -jump with ground jumping and jumping on the wall that Salto can do already to give these sages a leap to the nuts.
