01.01.1970 //the Robot- suit, which imparts force to man.
At the university at the university city Of tsukuba (Japan) robotokostyum ", which makes possible for the untrained person easy to raise weights at 70-80 kg or, without being bent, to bear on the arms load in 100 kg. this device can be used, for example, with the rescue operations in the zones of the natural calamities, with the prolonged physical labor, for restoring the people with the weakened muscles. The university Of tsukuby is ready to sell its "robotokostyumy" or to pass them to the lease. As they assume, Japanese model will become one of the series devices, called "ekzoskeletami". As reported today the press- service of university, sensors recover the weak electric pulses, which are formed in the muscles of man with the accomplishment of motions. They are synchronized with the action of the actuators of suit, which makes possible even for weak people to be converted into the heroes. Thus far the speed of this "prosthesis" is small, but in the near future developers expect to represent the brighter model, capable of developing the speed of the running person. "two-legged tanks" "with the aid of these systems of men will be able to transfer bulky loads at a high speed" the weight of prototype Hal -5 (HAL - "hybrid auxiliary foot", Hybrid assistive leg), which was being developed under professor yesiyukya's management Sankai, is 15 kg. it feeds device from the nickel-cadmium storage batteries, whose charge must be sufficient for two hours of work even more (depending on load). It is assumed that robokostyumy Hal -5 over the long term can use workers people with the limited physical possibilities, reports AFP. It is here necessary briefly to describe, with what devices the discussion deals. On the essence of its, ekzoskelety or the bionical suits (to the such it relates BY HAL) - these are the robots, slipped over man, which increase his physical force and endurance. It is expected that with the aid of these systems of men it will be able to transfer bulky loads at a high speed, and also they will help it to be oriented in the unknown locality. And, of course, the developments of such systems could not but interest servicemen. Actually, in the future of ekzoskelety they will make it possible to combine firepower of tank (due to the large weight of weapon and armor, transferred by soldier) with the mobility and dimensions of man. The agency of promising developments and research MO OF THE USA (DARPA, Defense Advanced Research Projects Agency), which sponsors these programs, it imposes the following requirements on ekzoskeletam: an increase in the physical force - soldiers must bear on themselves heavy weapon and other equipment; furthermore, after increasing their force, they can remove obstacles from their way while under power; an increase in the speed: the average speed of soldier - 4-6 miles an hour, in this case it must bear on itself 150 pounds of the load (however it is thus far unknown, with what speed will be able to move the man in you ekzoskelete); leaps to a high altitude and up to the distance. And although thus far still unclearly, is how highly and far can jump people in this system, servicemen assume that the soldiers must overcome higher and wider obstacles. After becoming more strongly, soldiers thus will become and more hardy they can overcome large distances. Furthermore, they can make the heavy equipment, which otherwise would not be possible to put into the working order. Ekzoskelety will be also equipped with sensors and built-in receivers of the system of global positioning (GPS), with the aid of which the soldiers will move to the given point along the unknown locality. In addition to everything specialists DARPA develop the computerized cloths, which will follow the regime of the work of heart and the respiration of soldier. Civil sector - more promising than the development DARPA - not the first attempt at the creation of such systems. In 1960- e years company General Electric developed electrical and hydraulic construction by the name Hardiman; however, it was not conducted with its weight into 1500 pounds of speech about its any effective use. And although now are used lighter materials (for example, carbon fiber) however problems nevertheless remain. In connection with their military science they be such: it ekzoskelet it must be made from the durable, light and flexible material, which moreover must protect itself, and soldier from the enemy fire; it ekzoskelet it must work as the minimum of 24 hours without the refueling, power unit also must enter into system; the creation of silent motor will be one of the most complex problems; means of control of system must be maximally convenient so that the user could freely function; user must have the capability of smooth and noiseless motions; developers must create the articulations such, which will be similar to the human, since if soldier in the battle is limited in the motions, then these limitations will be fatal for it. Summing up the sum, it is possible to say that it ekzoskelet it must in many respects resemble the man in his manner to move, sensitively to react to the human motions. As said science fiction writer Robert khaynlayn in the famous novel "starry landing" (Starship Trooper): "the brilliance of invention lies in the fact that the control is not at all necessary. Landing force member simply bears skeleton as suit, "as the skin". However, although DARPA isolated into financing of works on the bionical suits more than 50 mln. dollars. since 2000, to approach the ideal, described Khaynlaynom, until it succeeds. Probability that the servicemen will already next year obtain desired it ekzoskelet, is small - the existing operating times it is clearly insufficient, perhaps that suddenly will be found genius. Possibly, this and to the best, that instead of the production of the armored combat suits for the "terminators" the designers will give more than attention to the developments of civil models. As it is considered between man and androide, most successfully the regions of the especially peaceful application of ekzoskeletov master the Japanese. It is no secret that in this country in view of the different reasons (not lastly - because of the mass culture) is very great interest in the anthropoid robots - androides. Well and bionical suit is seemingly transitional version between the person, "intensified" by mechanical muscles, to the anthropoid mechanical "essence". By scientists from Tsukuby "begin on the heels" their associates from the university Of kanagava, under the management Yamamoto's Keydziro which developed that mechanized it ekzoskelet, who will allow nurses and doctors to raise patients from the bed, applying to this of no efforts. During the tests of the prototype of device the nurse with the weight of 64 kilograms could raise to the hands and transfer patient, who weighs more than it, 70 kilograms. It ekzoskelet it is metal frame with five pneumatic drives: on one for each elbow and each elbow and one on the back. The signals, which set them to the motion, come from the microcomputer, which reads data from the sensitive plates, placed on all basic groups of muscles, and attempts to govern ekzoskeletom in such a way that it would copy the motions of the person dressed in it. The prototype, which prepared Yamamoto's group, until it is too practical: it weighs 16 kilograms, and for person, who dressed him, it is necessary to drag after itself the monstrous confusion from the wires and the hoses, on which to the servomechanisms will be given the compressed air. Furthermore, its price is also unacceptable: it costs more than 21000 dollars. However, on the assertion of Yamamoto, all difficulties of ustranimy, and they will be removed in the nearest time. Processing the construction of ekzoskeleta, which will remove the need for the supply of electricity and compressed air from without, is already begun. Machine will become more easily and it is cheaper, and, as Yamamoto assumes, after only two years medical establishments can acquire the improved "descendants" of present ekzoskeleta for 250-300 dollars.
