  • Publication number: 20220289538
    Abstract: A method of controlling a movable body includes: a step of causing a sensor provided on the movable body to detect an obstacle; a step of determining the position and attitude of a front surface, of the obstacle, opposite to the travel direction of the movable body based on the detection result of the obstacle; a step of generating an avoidance path that avoids the obstacle while heading toward a side of a first direction intersecting the travel direction based on the position and attitude of the front surface; a step of causing the movable body to move along the avoidance path; a step of detecting the obstacle while the movable body is moving along the avoidance path; a step of determining the position and attitude of the side surface of the obstacle on the side of the first direction based on the detection result obtained during movement along the avoidance path; and a step of updating the avoidance path so as to return to a side of a second direction opposite to the first direction while avoiding the obsta

  • Publication number: 20220262132
    Abstract: A control method for a mobile object that automatically moves includes: causing a sensor disposed on the mobile object to detect a target object multiple times to acquire detection results of respective detection processes performed by the sensor as a point group; estimating a position and an attitude of the target object for each detection process based on the point group; calculating reliability of accuracy in an estimation result of the position and the attitude of the target object for each detection process; selecting, from among estimation results of the respective detection processes, an estimation result used for setting an approach path to a target position at which a predetermined position and attitude with respect to the target object are achieved based on the reliability for each detection process; setting the approach path based on the selected estimation result; and causing the mobile object to move along the approach path.

  • Patent number: 11118298
    Abstract: A washing machine capable of independently driving two rotors using one inverter in a simple configuration without supplying a composite current includes an outer rotor having a plurality of switching magnets arranged at intervals in the circumferential direction, and an inner rotor having a plurality of stationary magnets arranged to be radially arranged at intervals in the circumferential direction. When a magnetizing current is supplied to the coil of the stator, the magnetic pole of the switching magnet is inverted and the number of the poles of the outer rotor is switched.

  • Patent number: 10927491
    Abstract: A motor has a two rotors which are independently operated using a single inverter and without being supplied with a complex current. Further the motor is capable of shifting a rotation direction of each of two rotors by performing a magnetizing operation one time and reversing polarities of the shifting magnets when a mode of the motor is shifted from a synchronous mode in which the first rotor and the second rotor rotate in the same direction to a counter mode in which the first rotor and the second rotor rotate in opposite directions, and shifting the mode of the motor to the counter mode while the magnetizing operation is performed one time times and relative positions of the first rotor and the second rotor are changed when the first rotor and the second rotor inertially rotate in the synchronous mode.
