Abstract: Disclosed is a capsule type endoscope control system which can move to any position, rotate or stop the capsule type endoscope in a human body by a remote control system outside the human body.

Abstract: A micro robot driving system for endoscope can move a micro robot forward, backward or changing the direction by transmitting rotation force generated by a driving means to a worm gear or a gear tooth shaped belt by a worm. The micro robot driving system in accordance with the present invention includes a micro robot body, rotational force transmitting means installed in the body, for transmitting rotational force generated by driving means and movement means which is connected with the rotational force transmitting means, protruded from the body, for moving the body by rotational force transmitted by the rotational force transmitting means.

Abstract: A micro robot that can move for itself is provided. The micro robot moves by moving a plurality of legs with a plurality of cams driven by a driving device, which comprises a micro robot body, a rotational shaft installed in the body and connected to driving device for generating rotational force, a plurality of cams positioned sequentially and connected to the rotational shaft having a certain phase difference centering around the rotational shaft, a plurality of legs installed in the body capable of moving by rotation of the cams, said legs being abutted to the respective cams at one end portion thereof and protruding outwardly from the body at the other end portion thereof, respectively and a locomotion device for moving the body.

Abstract: A micro-robot for colonoscope with motor locomotion comprises an information detecting unit for obtaining information of the interior of the colon and a driving unit for generating its own locomotion and moving the information detecting unit without causing any damages to the walls of the colon.

Abstract: The present invention relates to an advanced forming apparatus for sheet blanks such as sheet metals or plastics, and in particular to a multi-purpose and multi-functional forming apparatus which can form sheets into products of various curved surface shape without using a die. The dieless forming apparatus includes an elastomer installed on one side of the sheet blank; a group of punches disposed at the opposite side of the blank, and having ends of various shapes applying a force to the formed material by movement; and a control unit controlling the movement of the press. In addition, a fluid may be filled in substitute for a part of the elastomer to evenly apply a force to the formed material, and a fluid control unit may be included to control a fluid pressure.

Abstract: A extendable/retractable linear actuator includes a rotational driving member having a rotational shaft, a rotational unit engaged to the rotational shaft of the rotational driving member, extended toward a rotational shaft direction, and rotatably driven in accordance with the rotational driving member, a plurality of radial bearings each respectively having a bearing rotation shaft inclined by an angle (.alpha.) against the rotational shaft axis direction, and symmetrically fixed to each opposing and surface of the rotational unit, and a cylindrical movement tube, surrounding the rotational unit, an inner periphery thereof being in contact with the radial bearings. The linear actuator is directed to minimizing the number of parts and decreasing friction between the parts, thereby accomplishing a simplified and cost-effective structure having an operational efficiency due to a small rolling friction.

Abstract: A foot system for a jointed leg type walking robot which is capable of more stably walking on both even and uneven ground surfaces includes a connection member disposed at a center portion of the foot system and connected to a leg system provided above the same and having a waist joint, a knee joint, and a shank, the connection member being cylindrical, an ankle member being integral with the connection member and below the same, a shock absorber supporting portion member outwardly and integrally extending at the outer surface of the ankle member and having a vertical hole formed therethrough, a shock absorber fixedly inserted into the hole formed in the shock absorber supporting portion member, and front and rear toes pivotally connected to the ankle by a plurality of upper and lower parallel links.

Abstract: An improved foot system for a jointed leg type walking robot capable of more stably walking on both even and uneven ground surfaces by providing a jointed leg type foot system with a front toe cylinder and a rear toe cylinder each communicated with a front toe assembly and a rear toe assembly. In addition, it is capable of more stably landing on uneven ground surface and absorbing landing impacts more efficiently, which includes a lower foot body; an upper foot body mounted on the top of said lower foot body; a gas accumulator formed within the lower foot body; a front toe assembly pivotally attached to a predetermined portion of the lower foot body; and a rear toe assembly pivotally attached to a predetermined portion of the lower foot body.

Abstract: A piston seal device of pneumatic cylinder which satisfies the required tightness of a seal as well as the required lubrication characteristics for a piston movement is disclosed. The piston seal device for maintining different pressures acting on each side of the piston of pneumatic cylinder comprises slide rings located on peripheries of both sides of piston, a seal ring located at the outer part of pressure room formed along the periphery of central part of the piston and operated by pneumatic pressure of the pressure room, and a solenoid valve which operates in selection modes to supply the pressurized air into the pressure room. Slide rings are located with a proper distance at the peripheries of both sides of a piston installed in a pneumatic cylinder and at the center of a piston an expansionable seal is applied.
