An objective of the present invention is to reduce the downtime which occurs when changing a servo motor device. A servo motor device includes a motor section and a reduction gear configured to output a driving force by reducing a speed of rotation of the motor section, wherein a control device includes a detecting section configured to acquire detected information about operation of the motor section, and a computing section configured to generate an approximate curve based on a behavior for a time sequence of a parameter and to calculate predicted lifetime information of the servo motor device based on the approximate curve thus generated, wherein the parameter has been calculated by means of the detected information.

Servo motor device, and control method

Provided is a movement robot configured so that various types of operation can be executed according to motion of other objects or a movement body and a utilization area can be expanded accordingly. The movement robot includes a robot body, a control unit, a traveling unit, and a detection unit. The control unitincludes a storage sectionconfigured to store detection information detected by the detection unitin chronological order, a map production sectionconfigured to produce a map of the periphery of the robot body, a movement body detection sectionconfigured to detect a movement bodydifferent from the robot body, a route control sectionconfigured to associate the map with robot route informationindicating a movement route of the robot bodyand movement body route informationindicating a movement route of the movement body, and an coordinated movement control sectionconfigured to move the robot bodyin coordination with the movement bodybased on the robot route informationand the movement body route information

Movement robot

A single passenger carrying mobile robot, includes a single operated member that is operated by a passenger to instruct both a moving direction and a moving speed of the passenger carrying mobile robot, a moving member configured to move the passenger carrying mobile robot and a controller configured to control the moving member based on input information input to the operated member by the passenger, wherein the passenger carrying mobile robot further includes a sensor that acquires obstacle information of a surrounding of the passenger carrying mobile robot, and the controller predicts an expected course of the passenger carrying mobile robot based on the input information and determines based on the obstacle information whether or not an obstacle is located in the expected course, and changes a control of the moving member when determining that the obstacle is located.

Passenger carrying mobile robot

A car having a rotatable wheel, the car being able to run by rotating the wheel, the car having a leg used by the car for walking, and an attitude stabilization section for stabilizing an attitude of the car.

Car, walking apparatus, and method of determining shape of wheel

A car includes a car body having a bottom portion, a wheel that is rotatable, and a supporting member for supporting the wheel, the supporting member being provided to the bottom portion. At least eight pairs of the wheel and the supporting member are provided. The supporting member has a first supporting portion for supporting the wheel rotatably, a second supporting portion for supporting the first supporting portion so that a direction of the wheel supported by the first supporting portion can be changed, and a turning portion that is rotatable about a rotation axis with its axial direction along a direction orthogonal to the bottom portion, the turning portion being provided to the bottom portion. The turning portion supports the second supporting portion so that a distance between the wheel and the bottom portion can be changed, and a position of the wheel can be moved by a rotation of the turning portion in a state that the distance is maintained.

A treadmill has a belt provided with a running surface and rotated in a predetermined direction at a set running speed, wherein a foot landing on the running surface is detected, a landing time distance between landing times is measured, and a stride is calculated from the running speed of the running surface and the landing time distance measured and indicated or recorded on an output device.

Treadmill

A method of processing a signal in a bar code reader in which an optical signal provided by scanning a bar code is subjected to photo-electric conversion to provide an analog electrical signal, which is utilized to decode the bar code. The method includes scanning a bar code with a light beam whose diameter is small enough to detect thin bars and determining whether the bar code is a thin bar code or a thick bar code. If the bar code is the thick bar code, the reader employs data based upon analog electrical signals, whose frequency components higher than a first cut-off frequency determined for the thick bar code are cut off, as effective data. If the bar code is the thin bar code, the reader employs data based on analog electrical signals, whose frequency components higher than a second cut-off frequency determined for the thin bar code are cut off, as effective data.
