The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
As shown in Figures 1 to 6, a kind of deformable multipurpose way soft robot, comprise and be the elastic shell 1 that round and axial centre place are provided with cavity, be provided with in described cavity for the skeleton 4 of camera 2 and load 3 is installed, between the lateral wall of described elastic shell 1 and madial wall, be provided with driver element.
Described driver element comprises the driving tube 6 of some fluid cells 5 and reciprocity quantity, described fluid cell 5 round that surrounds from beginning to end, described fluid cell 5 comprises cell membrane 501 and is located at the incompressible fluid 502 in cell membrane, described driving tube 6 is located at fluid cell 5 inboards, described driving tube 6 is connected across on two adjacent fluid cells, is provided with magnetic flow liquid 601 in described driving tube 6, for impelling magnetic flow liquid that micro-calutron 602 of " solid-liquid modality " occurs and for receiving and dispatching command information and controlling the controller 603 of micro-calutron work.
Described driver element is provided with 2 groups, and described driver element is located at respectively the both sides up and down of described cavity.
Described driver element at least is provided with 2 groups, and described driver element is uniform at circumferencial direction centered by described cavity.
Described fluid cell 5 is flats, comprises middle part and thin two thin coupling ends of protuberance.
The round of described driver element is radially radially perpendicular with the round of elastic shell 1.
The quantity of described fluid cell 5 has 6 at least.
Filled magnetic flow liquid in the driving tube cavity of deformable multipurpose of the present invention way soft robot, under the electromagnetic field effect produced at micro-calutron, magnetic-particle in magnetic flow liquid is magnetized, the direction that is extended down to magnetic line of force is lined up to chain structure, the yield strength of its material increases along with the increase of electromagnetic intensity, after withdrawing from magnetic field, material can restore to the original state again at once, and its response time only has several milliseconds.
Micro-calutron of driving tube inside and driving tube controller, after receiving the wireless control signal of upper computer, micro-calutron generates an electromagnetic field, make the magnetic flow liquid be filled in the driving tube cavity that " solid-liquid shape is changed " occur, due to expansion and the contraction of magnetic flow liquid volume, impel driving tube generation deformation, when driving tube successively deformation occurs, robot of the present invention will be moved, and reach the driving purpose.
As shown in Figures 4 to 6, sports rule of the present invention is as follows: under the controlled electromagnetic field effect at first produced at micro-calutron, " solid-liquid shape change " at first occurs in the driving tube at middle part, starts to soften, and makes two fluid cells of its cross-over connection to rotate freely; Then, " liquid-solid shape conversion " occurs in the driving tube at two ends under controlled electromagnetic field effect, starts sclerosis, makes two fluid cells of its cross-over connection move forward.
Along with the generation of these actions, driver element just can travel forward one and flow somatic length, thereby causes the front end lateral wall of elastic shell to overturn into, and the tail end madial wall flips out, and makes whole robot travel forward.
As shown in Figures 4 to 6, described fluid cell and driving tube are respectively 6, certainly in order to obtain, better carry out stationarity and more smooth-going path of motion, and fluid cell and driving tube number can correspondingly increase, and become 8,10,12 or more.
The present invention can be applicable to the narrow non-structured operating environments such as earthquake search and rescue, pipe inspection, medical diagnosis and military surveillance, can continuous deformation, and the obstacle detouring of can creeping on rugged ground, can be through the narrow structure less than oneself height.
Certainly, above is only concrete exemplary applications of the present invention, and protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
