Title
Design Of Cooperative Microrobots With Impedance Optimization
Abstract
This paper deals with the design optimization and development of cooperative microrobots. We realized several prototypes by microstereophotolithography (muSPL), actuated by shape memory alloy (SMA) wire micromotors. We are now about to integrate displacement and temperature microsensors. Our purpose is the cooperative micromanipulation of micro-objects (with their own dynamic) in the applications like micro catheters and micro-assembling devices. The capability to control the own impedance of our microrobots, both by an optimal design and the intrinsic ability of SMA micromotors to adapt their compliance and impedance, is taken advantage of. We introduce the thermomechanical behavior of SMA microactuators and the mechanical characteristics of polymer robot structure in an incremental dynamic model of the microrobot. We have obtained the impedance model of integrated microsystem and identified the main influencing design parameters. We have developed a neuronal bond graph (NBG) formalism that is used to the adaptive modelling of partial dynamic hystersis cycles.
