Apparatus and method for controlling network-based robot

An apparatus and method of controlling a network-based robot are provided. The apparatus includes a first connection unit connecting to at least one application component server or content server through a network, a second connection unit connecting to a wireless internet sharing router to communicate with the robot, and a middleware receiving and storing an application component from the application component server, executing the application component to generate an operational command for the robot, sending the generated operational command to the robot, and processing information which is sent by the robot. The apparatus and method provide a quick response to sensor information from the robot without incurring a burden of connecting to various service servers and managing the connections on the robot. In addition, a size of an internal buffer of the robot is minimized to enable the robot to respond to neighbor environments in real time.
