Patent number: 11905037Abstract: An aerial vehicle takeoff and landing system, an aerial vehicle takeoff and landing apparatus, and an aerial vehicle capable of reducing the influence of the ground effect and capable of taking off and landing smoothly even in a comparatively small and limited space. A pair of rails are arranged side by side with a gap therebetween, and are arranged with a space in an extension direction on at least an under side and one end side. An aerial vehicle has a suspension portion provided at an upper portion thereof so as to be inserted between the rails from the one end side. With the suspension portion is inserted between the rails, the aerial vehicle can be suspended at a predetermined landing position of the rails, and the aerial vehicle suspended at the landing position can take off.Type: GrantFiled: July 31, 2020Date of Patent: February 20, 2024Assignees: TOHOKU UNIVERSITY, NPO INTERNATIONAL RESCUE SYSTEM INSTITUTEInventors: Kenjiro Tadakuma, Satoshi Tadokoro, Kazunori Ohno, Yoshito Okada, Masahiro Watanabe, Daiki Fujikura, Toshi Takamori

Publication number: 20230045539Abstract: A passive guidance mechanism enables smooth guiding to a desired position; and a flying object landing system enables smooth guiding to and landing at a desired position. A pair of guide rails are arranged side by side with a space therebetween, and are provided so that the space increases toward one set of tips of the guide rails. One guide rail is supported so as to be rotatable about a first shaft extending in a direction perpendicular to a plane including the guide rails, at or near the tip of the guide rail. The other guide rail is supported so as to be rotatable about a second shaft extending in a direction perpendicular to the plane including the guide rails, at or near the tip of the guide rail.Type: ApplicationFiled: February 1, 2021Publication date: February 9, 2023Applicant: TOHOKU UNIVERSITYInventors: Masahiro WATANABE, Daiki FUJIKURA, Kenjiro TADAKUMA, Yoshito OKADA, Kazunori OHNO, Satoshi TADOKORO

Patent number: 10843506Abstract: An omni-directional rotational drive mechanism and a moving body in which production and maintenance can be facilitated, while the size can be reduced, by making the number of components smaller. A rotating body provided for a wheel member rotatable about a ring-shaped shaft having a rotating shaft of the wheel member as its center. The rotating body is configured to rotate integrally with the wheel member about the rotating shaft. A pair of worms rotatable about the same shaft as the rotating shaft of the wheel member. A pair of worm wheels are provided for the wheel member so as to be rotatable by meshing with different worms, and capable of transmitting each of rotations to the rotating body. The rotating body is configured so as to rotate or stop with respect to the wheel member in accordance with the rotational direction and the rotational speed of the respective worms.Type: GrantFiled: March 31, 2017Date of Patent: November 24, 2020Assignee: TOHOKU UNIVERSITYInventors: Kenjiro Tadakuma, Eri Takane, Masahiro Fujita, Masashi Konyo, Satoshi Tadokoro
