Abstract: The behavior of nanorod driven by AFM was analyzed, and a kinematics model of nanorod was established by introducing viscous friction which is relevant with the pushing velocity. Based on the model, the planning about the pushing parameters of AFM was debated and the nanohand strategy of zigzag stable pushing was presented to solve the problems raised by only one end effector of AFM and the uncertainty of nano scale. The simulation and experimental results showed that the instantaneous centre of nanorod at each manipulation could be determined by the kinematics model in real time. At the same time, the rod could be pushed into a bounded target area within a given probability by the nanohand strategy of zigzag stable pushing. So the stable and posture controllable nanomanipulation could be realized.
