A functional safety system of a robot according to an exemplary embodiment of the present disclosure can generate a safety zone which is a zone to sense whether an obstacle is present.

Apparatus and method for generating dynamic safety zone of mobile robot

The region segmentation apparatus and method for map decomposition of a robot according to the exemplary embodiment of the present disclosure segment the grid map into a plurality of regions in consideration of the graphic characteristic of the space and obstacles disposed in the space.

Region segmentation apparatus and method for map decomposition of robot

A wireless power transmitter includes an amplifier configured to amplify a power; a transmitter configured to resonate the power amplified by the amplifier; and a reference signal provider configured to provide a reference signal to the amplifier and change a frequency of the reference signal.

Wireless power transmitter

A synchronous direct current (DC)-DC buck converter and a method of controlling the waveforms of switching signals disclosed herein. The synchronous DC-DC buck converter generates a stepped-down output voltage using a first switch configured to apply an input voltage to an inductor and a second switch configured to switch in response to a second switching signal. The synchronous DC-DC buck converter includes a sawtooth generation unit, a driver oscillating signal generation unit, a switching signal generation unit, and a phase tracking unit. The sawtooth generation unit generates a sawtooth wave. The driver oscillating signal generation unit generates an error voltage between the output voltage and a reference voltage, and compares the sawtooth wave with the error voltage, so as to generate a driver oscillating signal. The switching signal generation unit generates each of the first and second switching signals. The phase tracking unit generates the frequency setting signal.
