Parallel VLSI architectures for real-time kinematics of redundant robots [PDF]
Journal of Intelligent & Robotic Systems, 1994 A key computational bottle-neck in real-time robot control is the calculation of the inverse kinematics which produces the time configuration history of the robot joints necessary to produce the desired end effector motion. The controller must solve the inverse kinematics problem to produce the correct trajectories.

Development of iRTK (iNVERTED Real-Time Kinematic) System Based on the Internet [PDF]
Journal of Astronomy and Space Sciences, 2003 We demonstrated positioning accuracy of iRTK system, which has been developed by Korea Astronomy Observatory, using a low-price GPS receiver. Each four different baseline positioning tests using the iRTK system, we certified 1-3 meters level positioning ...
