This paper presents a cooperative manipulation method for a non-contact robotic electromagnetic needle manipulation system. The manipulator employs two robotic electromagnetic needles with redundant degrees of freedom (DOFs) and an optimization-based control approach to achieve precise path following and collision avoidance.
In this paper, we report a cooperative manipulation method for non-contact robotic electromagnetic needle manipulation system. We employ two 3 degrees of freedom (DOF) robotic electromagnetic needles to achieve an over-actuated manipulator, which can move the particle to any position in the planar workspace from any direction. The redundant DOFs, combined with an optimization-based control approach, enable the manipulator to achieve accurate path following and avoid the collision of needles. Using visual servoing, the developed controller can achieve line following accuracy of 0.33 +/- 0.32 mu m, square following accuracy of 0.77 +/- 0.55 mu m, and circle following accuracy of 0.89 +/- 0.66 mu m with a 4.5 mu m diameter superparamagnetic particle. The manipulator can also manipulate a particle along complex paths such as infinity symbol and letter symbols.
