Abstract
Provided are an apparatus and method of calculating the position of a robot, which determine the position of a robot and create a map of the surroundings of the robot which account for the travel state of the robot. The apparatus includes a state variable calculation module which calculates a plurality of state variables regarding a travel state of the robot by using a plurality of Kalman filters; a travel state determination module which determines the travel state of the robot based on the results of the calculation performed by the state variable calculation module; and a state variable update module which updates the state variables according to the result of the determination performed by the travel state determination module.
