摘要:
A fluid-structure interactive analysis is performed while n types of wing structure models are caused to flap in accordance with a prescribed model of flapping manner. Based on an analysis, data 1, data 2, . . . data n of physical values related to fluid behavior and physical values related to structural behavior are calculated. Among data 1, data 2, . . . data n, a data having a prescribed parameter such as the lift force optimized is extracted. A prototype of a wing portion is formed, which has such a structure that is specified by various parameter values of the numerical model of wing structure corresponding to the extracted data. A driving unit 905 drives the prototype of the wing portion in a manner of flapping that is represented by the flapping motion model equivalent to the manner of flapping of an insect. At this time, the wing has a stiffness that is suitable for flapping flight so that prescribed parameters come to have optimal values.

On a main body portion of a fluttering apparatus, a wing (left wing) is formed which has a front wing shaft, a rear wing shaft and a wing film provided spreading over the front and rear wing shafts. Further, on the main body portion, a rotary actuator for driving the front wing shaft and a rotary actuator for: driving the rear wing shaft are mounted. The front (rear) wing shafts reciprocate in a plane orthogonally crossing an axis of rotation with the actuator serving as the fulcrum. Thus, a moving apparatus is obtained which has superior maneuverability and can move not hindered by any obstacle or geometry both indoors and outdoors.

A communication apparatus includes a transmitter and a receiver for communicating communication data containing transmission data transmitted from an operator; and a data (physical data of his/her surrounding environment) analyzer for outputting a mental state and/or a physiological condition of the operator by estimating it based on the communication data. The communication apparatus enables smooth communication between a sending end and a receiving end.

In a moving apparatus, flapping angle of a front wing shaft is γ+Δγ/2, and the flapping angle of rear wing shaft is γ−Δγ/2. Specifically, amplitude difference between front wing shaft and rear wing shaft is Δγ. Further, the flapping motion of front wing shaft is represented by sin (τ+φ/2), and the flapping motion of rear wing shaft is represented by sin (τ−φ/2). In other words, phase difference between the front and rear wing shafts is φ. Further, amplitude difference Δγ and phase difference φ are each represented by a function using a common parameter. Therefore, a control portion can independently change the amplitude difference Δγ and phase difference φ, so as to variously change a torsion angle formed by a tip end portion of the wing and a prescribed phantom plane. Thus, a moving apparatus that can make an efficient transition from hovering to forward or backward flight can be provided.

A numerical model related to fluttering of an insect, when an equivalent model of actual structure of a wing of the insect is moved in the air in accordance with a model of fluttering motion of the wing of the insect is calculated by fluid-structure interactive analysis, in which behavior of the wing and behavior of the air are given as numerical values, including interaction therebetween. Thereafter, a method of controlling a fluttering robot, wing shape and the like are determined by modifying numerical models of fluttering of an insect prepared by fluid-structure interactive analysis, in accordance with sensitivity analysis. Accordingly, a method of preparing numerical models of wing and air considering the behavior of the wing of the insect in the air is provided and, in addition, a method of manufacturing a fluttering robot utilizing the numerical model prepared by this method of preparing numerical model can be provided.

A search robot system first divides the entire area of disaster into a mesh cell of an appropriate size, and arranges a search robot for each mesh cell. A search is made for a route of travel from an outermost mesh cell to a casualty and to an adjacent mesh cell. The search robot immediately communicates with a mother robot when a casualty is found. The search robot also communicates with the mother robot when a route to an adjacent mesh cell is found. In the search robot system, a new search robot is arranged to search in an adjacent mesh cell. Accordingly, a rescue activity that is a matter of time can be carried out by a plurality of robots.

A group robot system includes a plurality of sensing robots and a base station controlling the sensing robots, and establishes communication in a hierarchical manner. The hierarchical structure is formed of a plurality of levels between a plurality of sensing robots with base station as the highest hierarchical level. The first sensing robot detects an object; the second sensing robot conducts further search on the object; and the third sensing robot conducts communication relay between the first sensing robot and the base station. When the first sensing robot detects an object, the base station provides control such that all sensing robots, other than the first, second and third sensing robots, move outside the current area of search.

A flapping apparatus includes a first disk rotated by a driving source, and a second disk that rotates in contact with a main surface of the first disk. The second disk is provided with first and second stoppers that limit its angle of rotation. When the stopper is in contact with the first disk, rotation of a wing shaft is caused only by the rotation of the first disk, and when the stoppers are not in contact with the first disk, rotation of the wing shaft is caused only by the rotation of the second disk.
