A target route generation system which generates a target route for a robot (R) to travel along autonomously is provided with a route candidate generation element (110) which generates a plurality of travel route candidates to connect the terminating point and the starting point by connecting links stored at a link storing element (211), state recognition elements (115 to 118) which recognize a state of the robot (R), and a route evaluation IC element (120) which evaluates a cost of a travel route candidate including therein an action point stored in an action point storing element (212) lower as the necessity for passing by the action point is higher in view of the state of the robot (R) recognized by the state recognition elements (115 to 118). According to the system, the robot can be made to travel through the action point with a high necessity in view of the state of the robot.

A position detection apparatus that is able to easily detect self-position during autonomous movement by a humanoid robot that moves by the use of legs or automobile. The position detection apparatus detects the position of a moving object, said position detection apparatus being provided with a brightness image acquisition device that acquires a brightness image of the forward field of view of the moving object, a distance image acquisition device having the same field of view as the brightness image acquisition device that acquires a distance image simultaneous to acquisition of a brightness image by the brightness image acquisition device, a characteristic point extraction device that extracts respective characteristic points from the brightness images of at least two consecutive frames, and a reference characteristic point selection device that calculates the amount of displacement of a position between two frames of a characteristic point extracted by the characteristic point extraction device based on a distance image, and selects a reference characteristic point for calculating self-position according to said amount of displacement.

An internal combustion engine in which a three-way catalyst (12) for purification of the exhaust gas is arranged in the exhaust passage, wherein the relationship between the magnitude of the stress causing deterioration of the three-way catalyst (12), for example the catalytic bed temperature, and the rate of deterioration of the performance of the catalyst is found. A durability test is performed by raising the catalytic bed temperature higher than that of the vehicle under market driving. The length of the durability test at this time is determined from the relationship between the catalytic bed temperature and the rate of deterioration of the performance of the catalyst so as to give the same degree of deterioration of the performance of the catalyst as with market driving. The length of the durability test required for giving the same degree of deterioration of the performance of the catalyst is much shorter than the market driving time.
摘要:
A device for evaluating catalyst performance deterioration includes an air-fuel ratio sensor and a temperature sensor. The degree of catalyst performance deterioration per unit time is calculated based on the concentration of oxygen in the exhaust gas and the temperature of the catalyst. The deterioration of the catalyst is evaluated on the basis of the accumulated value of the degree of catalyst performance deterioration per unit time.

A remote controller enables a user to manipulate behavior of a robot so that the robot does not stray away from a given area and also avoids contact with an object. If a route designated by the user satisfies a stable movement requirement, a first command signal is transmitted from the remote controller to the robot. By doing so, it is possible to move the robot according to the designated route. On the other hand, if the route designated by the user does not satisfy the stable movement requirement, the first command signal is not transmitted from the remote controller to the robot. Therefore, it is possible to stop the robot from moving according to the designated route, and further to avoid the situation where the robot strays away from the designated region, or comes into contact with the object.

To automate the work of recognizing a guest, check the appointment, notify a host of the arrival of the guest and conduct the guest to a designated place, a robot having a function to autonomously travel is equipped with camera/microphone for recognizing a guest at least according to image information. The system comprises management database adapted to communicate with the robot and equipped with an information database for identifying the recognized guest, and identifies the guest according to the information obtained from the camera/microphone and management database. The robot recognizes the guest from the image thereof, and the recognized guest is identified and verified by comparing the image of the visitor with the information contained in the database so that the robot can automatically conduct the guest to the designated meeting room according to the information of the appointment stored in the database.

摘要:
In a route generating system for an autonomous mobile robot, a plurality of nodes are designated within an area of movement of the robot and an edge is defined between a pair of nodes only if a distance from the one node to the other node is less than a threshold value and there is no obstacle on a line drawn between the one point and the other point. Because the route is generated from a collection of pre-defined edges which are free from obstacles and are selected so as to optimize the generated route, the robot is enabled to travel from the current position to the destination in a safe and optimum fashion. Furthermore, the edges are defined by connecting only those nodes that are relatively close to each other, the candidates of the edges for generating a route can be reduced to a small number and this reduces computational loads. Also, because the route can be selected in a relatively intelligent manner so as to optimize a certain criterion, a clumsy appearance in the movement of the robot can be avoided.
