Abstract: The present work deals with the investigation of the hybrid bio-mechanical mechanism for nanorobotic propulsion. The thrust force has been obtained from the unzipping of a dsDNA and utilising the force hysteresis pattern obtained during unzipping and rezipping of a dsDNA. The feasible DNA based hybrid bio-mechanical actuator model which is considered for usage for locomotion of nanorobots in a liquid medium has been studied, analysed and investigated.

Keywords: piezoelectrics; nanorobots; nanopropellers; de-oxy ribose nucleic acid; DNA; biomechanical actuation; robot propulsion; force hysteresis patterns; actuator modelling.
