Abstract: Provided is a fruit and vegetable harvesting device (10) for harvesting a fruit or vegetable (1) connected to a branch (3) via a pedicel (2). The fruit and vegetable harvesting device (10) includes: a harvesting hand (11) including a holding unit (12) having a suction pad (15) for holding the fruit or vegetable (1) and a finger unit (21) that can abut on the pedicel (2); and a robot arm (31) that turns the harvesting hand (11) to cause the finger unit (21) abutting on the pedicel (2) to press the pedicel (2).

Abstract: In an encoder constituted from a detection part (a light-emitting part, rotating disk, and light-receiving part), which detects a signal corresponding to the state of a specimen, and calculates and stores the position information of the specimen from a signal outputted from this detection part, and a signal processing part for transmitting the stored position information to a host machine by way of serial communications, the signal processing part being constituted having: a two-way communication mode M1 for receiving command data from the host machine, and, when this command data is a two-way communication request command (commands A through C), transmitting the requested position information and the like to the host machine; a one-way communication mode M2 for transmitting the position information to the host machine by executing one-way transmission processing S105 when the command data is a one-way communication request command (command P); and a quasi one-way communication mode M3 for transmitting the po

Abstract: To provide a motor controlling device that reduces heat generated by an armature and switching elements when an alternating motor is activated. A motor controlling device includes: an H bridge circuit 20 that has FET1 to FET4 that connect and disconnect a high potential end HV and a low potential end GND of a direct-current power supply to and from an armature Lu; and an energization control unit for controlling the amount of energization of the armature Lu by the PWM control that involves changing the ratio, in a predetermined control cycle, between an energization control period, in which the FET1 and the FET2 are turned on and the FET3 and the FET4 are turned off, or the FET3 and the FET4 are turned on and the FET1 and the FET2 are turned off, and a non-energization control period, in which the FET1 and the FET3 are turned on and the FET2 and the FET4 are turned off, or the FET2 and the FET4 are turned on and the FET1 and the FET3 are turned off.
