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.
