Abstract: The present disclosure relates to a kinematics calibration method for a robot with multiple degrees of freedom. The robot includes a base, an end effector, and a plurality of links connected by joints. The method includes locking part of the multiple degrees of freedom by limiting the base and the end effector impose a limitation of degree of freedom; moving the robot to perform a first movement and accordingly obtaining a first set of data associated with joint angles and a first actual motion of the end effector; calculating a first theoretical motion of the end effector based on the first set of data and initial kinematics parameters; and updating the initial kinematics parameters of the robot to obtain a first set of updated kinematics parameters based on the first theoretical motion and the first actual motion.

Abstract: A method, system, and non-transitory, computer-readable medium are provided for estimating a direction of gravity with respect to a robot. The method includes rotating a first joint. A first torque information of the first joint is recorded during rotation of the first joint. A second joint is then rotated. A second torque information of the second joint is recorded during rotation of the second joint. The direction of gravity is then estimated with respect to the robot based on the first torque information and the second torque information. The method provides an efficient way for determining the direction of gravity with respect to the robot.

Abstract: Systems and methods provide a mechanism to create and maintain web pages and other types of output pages. The system and methods use an author markup language (AML) to define output pages. Additionally, a Component Markup Language (CML) may be used to define components that may be referenced by the AML. The AML and CML may be translated to an intermediate format, which may then be further processed at runtime to combine dynamic data with the intermediate format to produce the output page.

Abstract: Methods and apparatus for selecting a system for communication with a personal station, such as a cellular telephone or a PCS station, in a roaming area. The personal station transmits a system access message to a default system. When the default system that receives the system access message is a visited system in the roaming area and the personal station is not registered with the visited system, the visited system registers the presence of the personal station in the roaming area with a home system for the personal station. The home system sends a response including a selection indication to the personal station through the visited system. The selection indication contains selection information for controlling selection of a system for communication with the personal station in the roaming area. The personal station selects a system for communication in the roaming area in accordance with the selection information.

Abstract: In a cellular system configuration, the location of a mobile station is determined from the acquisition of cellular network data pertaining to the mobile station, and the translation of such network data into a corresponding geographical position profile. The cellular system includes a mobile station locator entity for receiving from a mobile switching center the network data such as cell and/or sector ID and trunk group member number. The mobile station locator translates the network data into position information such as geographic coordinates (latitude and longitude), resolution (radius), and angle values for sectorized cells.
