Abstract: In an abnormality detection system of a mobile robot, it is configured such that it is self-diagnosed whether the quantity of state is an abnormal value, or whether at least one of the internal sensor, etc., is abnormal and when an abnormality is self-diagnosed, abnormality information affixed with a time on which the abnormality occurred is outputted to be stored in an internal memory and in an external memory. With this, it becomes possible to improve the reliability of abnormality detection of the mobile robot and by storing the information affixed with a time on which the abnormality occurred, it becomes possible to ascertain accurately the course of events leading up to the abnormality. It is further configured such that in addition to a time on which the abnormality occurred, the information is stored in an external memory together with a parameter indicative of the quantity of state.
Abstract: In a legged mobile robot control system having leg actuators each driving the individual legs and arm actuators each driving the individual arms, an external force acting on the right arm is detected, operation of the right arm actuators is controlled to produces a handshake posture, and operation of the leg actuators is controlled based on the detected external force acting on the right hand during handshaking, thereby improving communication capability by enabling it to shake hands with humans and to maintain a stable posture during the handshaking.

Abstract: The present invention aims to provide an autonomous moving robot capable of visibly showing the human an initial check result for a sound input means in the initial stage after the robot device is turned on and activated, and whether or not the input sound was normally recognized. The robot has ears 9a, 9b respectively comprising microphones 10a, 10b for external sound input, and LED displays 11a, 11b with a plurality of luminescent portions around the respective microphones. The luminescent portions of the LED displays 11a, 11b indicate the judgment of the initial check on whether or not the ears 9a, 9b (the microphones 10a, 10b and the LED displays 11a, 11b) are normally functioning when the robot is turned on and activated, by means of the lighting states of the displays.
Abstract: A target object detection apparatus for identifying a target object by using at least a camera and a wireless tag provided on the target object which exists outside of the target object detection apparatus, comprising: a target detector for reading a first identification information documented in the wireless tag; an image processor for extracting a first image information of the target object imaged by the camera; a personal identifier for identifying an imaged target object by comparing the first image information extracted by the image processor and a second image information specific to the target object; and an integration processor for determining a third identification information of the target object based on at least a second identification information identified by the personal identifier and the first identification information read by the target detector.
Abstract: A method of appropriately controlling functions of a moving body having a joint such as a robot in view of the content of an error detected in the functions of the moving body. A mode setting section (112) sets “a first mode” for halting first and second functions at least after the end of a starting period of the robot (200) in response to the detection of “a first error” by an error detecting section (111). The mode setting section (112) halts the first function at least after the end of the starting period in response to the detection of “a second error” by the error detecting section (111), while setting “the second mode” for adjusting control unit (100) or the like using the second function during the starting period. Furthermore, the mode setting section (112) sets “the third mode” for moving the robot (200) using the first and second functions in response to the detection of “a third error” by the error detecting section (111).
Abstract: In an abnormality detection system of a mobile robot, it is configured such that it is self-diagnosed whether the quantity of state is an abnormal value, or whether at least one of the internal sensor, etc., is abnormal and when an abnormality is self-diagnosed, abnormality information is outputted, then the degree of abnormality is discriminated based on the outputted abnormality information and the robot is driven into a stable state in response to the discriminated degree of abnormality. With this, it becomes possible to effectively utilize the abnormality detection result. In addition, since the robot is driven into a stable state in response to the discriminated degree of abnormality, it becomes possible to render the driving appropriate.
Abstract: A legged moving robot has an action plan function to operate according to a predetermined action plan. The legged moving robot has a fuel cell for supplying operating electric energy for the legged moving robot, an operation control unit for controlling operation of the legged moving robot according to the action plan, and an electric generation managing unit for monitoring a state of the fuel cell and contents of the action plan and for regulating an amount of electric energy generated by the fuel cell depending on the action plan.
