Development of a piezo-actuated micro-teleoperation system for cell manipulation.
BACKGROUND Intracytoplasmic sperm injection (ICSI) requires long training and has low success rates, primarily due to poor control over the injection force. Making force feedback available to the operator will improve the success rate of the injection task. A macro-micro-teleoperation system bridges the gap between the task performed at the micro-level and the macroscopic movements of the opera...
متن کاملPrecision Control of a Piezo-Actuated Micro Telemanipulation System
Piezoelectric actuators are widely used in micro manipulation applications. However hysteresis nonlinearity limits accuracy of these actuators. This paper presents a novel approach for utilizing a piezoelectric nano-stage as slave manipulator of a teleoperation system. The Prandtl-Ishlinskii (PI) model is used to model actuator hysteresis in feedforward scheme to cancel out this nonlinearity. T...
متن کاملDevelopment of a Piezo-actuated Robot for Cell Injection
In the presented work model and experiments of compliant robots with piezo actuators are carried out. The robot is designed to perform automatic injection of cells in the range of 10-30 μm. A kinematics model of serial-parallel structures is presented. Pseudo rigid body approach is used, where the elastic joints are modelled as revolute joints. Models for tension of parallel structures with ela...
