Abstract :
This paper investigates uncalibrated control schemes for vision-guided robotic tracking of a moving target using a moving camera. These control methods are applied to an uncalibrated robotic system with eye-in-hand visual feedback. Without a priori knowledge of the robot´s kinematic model or camera calibration, the system is able to track a moving object through a variety of motions and maintain the object´s image features in a desired position in the image plane. These control schemes estimate the system Jacobian as well as changes in target features due to target motion. Four novel strategies are tested.
