  • Patent number: 11797011
    Abstract: Provided are a traveling control system for a transport vehicle and a traveling control method for a transport vehicle capable of preventing unstable traveling when the transport vehicle travels while pulling a bogie. The traveling control system for a transport vehicle includes an imaging unit (3) provided corresponding to an operation region of a bogie (2) that travels together with a transport vehicle (1), a mode acquisition unit (14) configured to acquire a mode of the bogie based on an image including the bogie imaged by the imaging unit, and a mode determination unit (14) configured to determine a mode of the bogie based on the mode of the bogie acquired by the mode acquisition unit. Traveling of the transport vehicle is controlled based on a determination of the mode determination unit.

  • Patent number: 11392136
    Abstract: An automated guided vehicle system in which an automated guided vehicle autonomously moves inside a building is provided. The automated guided vehicle includes: an internal sensor having an encoder and a gyro sensor and acquiring information about an own position; an external sensor casting light onto a reflection board arranged in the building, receiving reflected light from the reflection board, and acquiring information about an own position; and a control unit correcting the own position based on the internal sensor, based on the information acquired by the external sensor. The own position via the internal sensor has a margin of error such that the automated guided vehicle can travel for a predetermined period, using only the internal sensor. The control unit performs own-position correction via the external sensor, using one of the reflection boards.

  • Publication number: 20160184996
    Abstract: In order to provide a robot which easily calibrates a manipulator, a robot includes an arm and a force sensor, in which the arm is calibrated by causing the arm to take a plurality of attitudes on the basis of an output value from at least the force sensor in a state in which a part of a first member attached to a tip of the arm is moved so that a distance between the part and a second member becomes a distance of 1 for each of a plurality of second members, the part being provided at a position which is not present on a rotation axis of the tip of the arm.
