| الملخص: | Vision is a useful information for manipulation tasks since it provides a large
spectrum of details about the environment. The visual feedback information
can be used to guarantee the manipulation accuracy and improve robustness
to uncertainty. In this paper, a vision-based adaptive control method is
proposed for micromanipulation using optical tweezers. A general model of
robotic manipulator is introduced in the optical tweezers system so that the
movement of the laser beam is controlled by vision-based closed-loop robotic
manipulation techniques. A new adaptive Jacobian controller is proposed
for the regulation problem in presence of camera calibration errors. The
stability of the closed-loop system is analyzed with consideration of the
dynamics of both the particle and the robotic manipulator. Simulations are
presented to illustrate the performance of the proposed method. |
