Abstract: Disclosed is a robot. The robot comprises: a driving unit including a motor, and a processor configured to: determine a driving level of the robot based on surrounding environment information of the robot based on receiving a command for performing a task of the robot, determine, based on information about a maximum allowable torque and information about a maximum allowable speed which are preset for each driving level, a maximum allowable torque and a maximum allowable speed corresponding to the driving level of the robot, calculate the maximum allowable acceleration of the robot based on the maximum allowable torque, control the driving unit to control the robot to control the moving speed of the robot to reach the maximum allowable speed based on the maximum allowable acceleration, and control the robot to perform tasks while the robot is moving at the maximum allowable speed.

Abstract: A data flip-flop circuit includes a flip-flop, a recovery latch and a cut-off transistor. The flip-flop stores a data signal that is input, using a clock signal and a virtual power supply voltage and provides the stored data signal as an output signal at an output node in response to a rising transition of the clock signal. The recovery latch is connected to a power supply voltage and a ground voltage, is connected to the flip-flop at the output node, stores the output signal internally in response to a first transition of a chip enable signal, recovers the stored output signal in response to end of a power gating interval based on the chip enable signal, and provides the recovered output signal to the flip-flop. The cut-off transistor floats the virtual power supply voltage provided to the flip-flop based on a first power gating signal.
