  • Publication number: 20240066691
    Abstract: There is provided a robot device that implements unloading or loading of a load to a loading platform, with less degrees of freedom. The robot device includes a loading unit on which a load is placed, a posture changing unit that changes a posture of the loading unit, a moving unit that moves the loading unit, a taking-out unit that takes out the load placed on the load receiving surface and moves the load to the loading unit, and a control unit that controls operation of the posture changing unit and the moving unit. The control unit performs force control of the posture changing unit to cause the loading unit to follow the load receiving surface, and then controls the taking-out unit to take out the load placed on the load receiving surface and move the load to the loading unit.

  • Publication number: 20230170713
    Abstract: An object of the present technique is to favorably prevent an excess current upon initial charging of a capacitor for assisting power supply. A control unit is provided that controls a power system in which a power supply is connected to a load via a power supply line, a capacitor for assisting power supply is connected to the power supply line via a first switch, and the capacitor is configured to be charged while being subjected to current limitation due to intermittent driving by a switching power supply using the power supply as input. The control unit is configured to control the switching power supply so that an output voltage thereof becomes equal to a voltage of the power supply line and to control the first switch from an off-state to an on-state after charging of the capacitor is completed to connect the capacitor to the power supply line.

  • Publication number: 20220231519
    Abstract: An apparatus and a method capable of performing a power source switching process and a charging process without stopping electric power being supplied to a load are implemented. A configuration includes a first switch circuit provided between a first power source port and a load to be supplied with electric power; a second switch circuit provided between a second power source port and the load; and a controller that controls the first switch circuit and the second switch circuit. The controller performs, on each switch circuit, a process of switching between three states, that is, (a) an ON state, (b) an OFF state, and (c) a diode operating state, thereby performing a process of switching between power sources connected to the respective power source ports without stopping the electric power being supplied to the load. Further, the controller performs battery charging with a regenerative energy resulting from a rotation of a motor that is the load.
