by Jeffrey Thompson·Comments Off on Shape shifting bots could be the key to planetary exploration
Sticks and stones may break your bones, but rods and cables may one day help NASA explore planets.
For a few years now, scientists at NASA’s Ames research center and students from the University of California Berkeley’s Best Lab have teamed up to create so-called tentricity robots, which they hope to one day use for planetary exploration. These structures rely on a constant interaction between compression and tension.
Because the robots have no rigid connections, their shapes can be deformed using a series of small motors. The motors pull on the cables and make the bots move by either rolling or hopping.
Currently, NASA needs to go to great lengths to land a rover on a planet. Take, for example, the Curiosity Rover, which required researchers to use a parachute and sky crane to gently lower the rover onto the surface of Mars back in 2012. On the other hand, tentricity robots are built to be rugged and can absorb a heavy impact without breaking, meaning they can simply be dropped onto a planet without the need of expensive landing gear.
Another advantage is mobility. The ability of tentricity robots to alter their shapes means that they move about in a variety of environmental conditions.
Researchers say tenricity robots are still at least 10 years away from being used on missions, but they are optimistic the bots will one day provide a cheap, lightweight alternative to traditional rovers.

Samsung destroyed many hearts when it declared that its forthcoming main smartphone the Galaxy S8 wouldn’t find an MWC launching. It was in the news again quite recently when the leaves of the approaching main leaked online.
Analysts say that its sib Samsung Galaxy S8 Plus would do with regard to sales than Galaxy S8.
Galaxy Flagship Smartphones Past Sales Records
During the launching of Galaxy S6 advantage and Galaxy S6, in 2015, Samsung made a serious miscalculation.
The entire premise turned out to be a total wreck and it became apparent that folks were interested in purchasing the premium and fashionable Galaxy S6 advantage over the Galaxy S6, because of the superior version’s double- screen that was curved.
As it didn’t produce enough Galaxy S6 advantage handsets to satisfy the tremendous demand, owing to this little blunder, Samsung lost out on lots of prospective sales. Per reports, both the associates that were retail and carrier associates demanded more of Galaxy S6 advantage compared to the Galaxy S6.
Estimated computations say that 70 percent of Galaxy S7 sales were credited to Galaxy S7 edge
Galaxy S8 Plus vs Galaxy S8
With Samsung gearing up to start Galaxy S8 Plus and the Galaxy S8, the rivalry will be a little challenging this time as both the smartphones will purportedly be featuring a double-border curved screen and characteristics that are similar.
The single facet which might discern both versions might be the screen sizes.
Samsung, predicated on its Galaxy smartphone encounters that are previous, will be expecting the Galaxy S8 Plus outsells S8 to the Galaxy. But, the very fact that both versions may place nearly indistinguishable attributes may make this year’s sales forecasts a little crafty.
