Under www.wissenschaft.de there is an intersting article regarding the hopping spherical robots today.

The article says that the astronomers are very interested in them and that there is real work on them at present.

These small spherical robots are to spread out on Mars by hundreds or even thousands, investigate and analyze the soil and search for water.

The researches want to inserted into the interior of the spheres not only miniaturized tools for soil analysis, radio communication and providing energy but a mecahnism for motion also.

The single sphere will keep a particular position like a stand-up-dwarf. At ground feather-elements will release themselves so that the sphere rolls to a particular direction or even hops.

These spherical robots are under development to fill agap - they enable to get and keep direct contact to the soil while in pararlel access a larger area than Spirit and Opportunity - including taking samles.

By ariund 1000 spherical robots an area of 130 square-kilometers is intended to be investigated to the final corner. Even small holes and caves in the ground would be accessed - because of the large number of the spherical robots it wouldn't be that a problem if a single robot doesn't manage to get out of such a hole or cave.

First field tests are going to be started this autumn. Commercially available elements. components. parts will be used which in many ccases are miniaturized already - harddisks of a diamter of a 2-Euro-coin for example, sensors of the size of a match.

The enrgy source is said to be a challenge - a fuel cell providing enrgy for a hundred hops at least, the other elements, components and parts and keeping the required temperatur for work.

By the ongoing miniaturization of electronic components during the next years the researchers exppect to reduce the weight of the single sphere to 100 grams and the length to 10 centimeters.

The article refers to the team around Steven Dubowsky, Massachusetts Institute of Technology (MIT), Cambridge as well as to the Online-Service of Science - sciencenow.sciencemag.org .

Under www.wissenschaft.de there was an article 5th of October reporting that two american researches have produced artificial sensitive hairs like those cats, dogs and other animals have at their noses.

These articial hairs are capable to recognize the three-dimensional shapes of objects as well as the strength and direction of currents in liquids or atmospheres.

The manner in which animals are applying their hairs also tells them the distnce of the objects or currents. The information is got from the degree to which the hairs are bowed (correct translation of "biegen" ?).

This all has been tested already and turned out to work. The scientists are going to improve the sensitivity of their artifial sensitive hairs.

This technology explicitly could be applies then as component of the exploration of planets. ...

The article refers to Joseph Solomon and Mitra Hartmann (Northwestern University, Evanston): Nature, Vol. 443, page 525 ( www.nature.com )

Under www.welt.de there is an article today reporting that british researchers have developed a fly-like robot that can be used for military spying. It is as small as a fly - and it might be capable of carrying very small amounts of explosive to destroy a computer for example in order to not have to destroy the compelte building hte computer is located in.

So what about using such fly-like robots for exploring and researching Mars also?

Since they are that small and light - would it be posssible to get them flying in the extremely thin martian atmosphere also by increasing their wings by a factor of 100 or so?

Yesterday under www.wissenschaft.de another new found mechanism has been found that robots might use.

The mechanism is like a muscle. There are pulsing gels that are contracting and expanding in contact to liquids and removing the liquids. They are called Belousov-Zhabotinsky-Gels.

The liquids must contain nitrogen.

This is known since 1996 - but now the exact degrees of contraction and expansion as well as their directions etc. might be calculatable. There was a simulation in which it succeeded.

The article refers to Victor Yashin and Anna Balazs of the University of Pittsburgh, the Online-Service of New Scientist, 3rd of November ( http://www.newscientisttech.com/article ... vices.html ) and - regarding the original of the article - Science, Vol. 314, page 798 ( http://www.sciencemag.org/cgi/content/a ... 4/5800/798 ).

The german Fraunhofer-Institut for Productiontechniques and Automation has managed to develop an artificial muscle providing extreme movability of "Gelenke", big forces and costs by a third less than earlier solutions.

That muscle is called a breakthrough and is driven by electromotors. It's called Dohelix and operates arms, legs and, fingders of robots.

The Institut in Stuttgart/Germany says it to be completely comparable to its human counterpart.

It's going to be priced at less than 10,000 Euros while the previous systems are priced at 30,000 Euros and more.

This has been reported ban article in the most recent edition of Wirtschaftswoche

According to an article under www.welt.de from 11th of February this year NASA ist testing a new kind of robots in the arctic region.

The nw kind of robot is Tumbleweede-like and can achieve speeds of up to 160 km/h - the article says that martian winds are of up to that speed. Initial analysises by the JPL are siad to have shown up that this way distance of up to 1000 km can be covered.

Tumbleweed1 has a diameter of 2 meters and achieves a speed of 6 km/h in the artic region. It's transmitting temperature, pressure, humidity and intensity of light during its travel.

Tumbleweed1 weights 45 kg - and the robot is going to be prepared for a Mars-mission. Because of this the weight has to be reduced to 50%.

It can stop by releasing air and taking in it again to continue the journey. Even changes in wind as well as surface features can make it stop for researches.

It is capable of surviving crashes from hills into the surface by 100 km/h without damages and might go Mars in 2013. NASA is said to have in mind to send it to Venus, Io and Triton as well. It is very cheap.

According to an article under www.wissenschaft.de swiss scientists have developed a robot that weigh 7 grams only and is capable of jumping 1.4 meters wide - by just one jump.

It has an elastic storage mechanism capable of slowly collecting energy and then releasing it suddenly. A motor weighing 0.6 grams loads two torsion springs that catapult the robot. A small battery enables 320 jumps within 3 seconds.

The scientists explicitly say that this robot might explore other planets.

The article refers to Eidgenössischen Technischen Hochschule Lausanne ( www.epfl.ch/ ) and IEEE-Conference, Pasadena ( icra2008.usc.edu/ ).

Regarding the robot Tumbleweed1 the article listed an interesting link I looked for when looking for the article yesterday: mars.jpl.nasa.gov/spotlight/tumbleweedAll.html

According the link this robot seems to be much larger than the german article says.

There was an article about DARPA's robocup under www.welt.de . Obviously robots in between are going to be capable of playing soccer in the next few decades.

This would mean that they will not need to be rovers then no more but might walk.

Would this be a significant progress for the exploration of planets like Mars? Would such a robot be faster than the rovers on Mars as well as on the moons of the outer planets inclduing the dwarfs?
