PURPOSE: An error correction method according to an incident angle of a distance measurement sensor is provided to more accurately measure a distance to a measurement object by correcting an error of distance measurement according to an incident angle when a light source of a distance measurement sensor meets a measurement object. CONSTITUTION: An error of measured distance according to an incident angle of a distance measurement sensor is statically calculated(S110). A distance from the distance measurement sensor to a measurement object is measured(S120). A distance of coordinates within a predetermined region of the measurement object through pan-tilt motion of the distance measurement sensor is calculated(S130). A plane vector PT of the surface of the measurement object is calculated utilizing the distance values of the measured predetermined coordinates(S140). An incident angle which a light source of the distance measurement sensor and the measurement object make using a formula is calculated(S150). A correction distance error is calculated according to the incident angle which the measurement object and a corrected distance dc is obtained by correcting the measured distance dm in the distance measurement sensor(S160).

PURPOSE: A framework system for controlling the motion of a robot and a robot motion control method using the same are provided to allow for independent development of device, application, and control modules because the modules are indirectly connected through a core module. CONSTITUTION: A framework system for controlling the motion of a robot comprises a device module(110), an application module(120), a control module(130), and a core module(140). The device module stores information on the structure of a robot. The application module stores information on applications that can be implemented by a robot connected through the device module. The control module receives status parameters of the robot through the device module and implements control algorithm through the applications of the application module using the received status parameters. The core module implements communications by connecting the device, application and control modules.
