The need for low-cost robust meso-scale smart §robots (manipulators) that have no discrete parts §(monolithic), no sensors ( self-sensing ) and can be §used in space-constrained systems, e.g., in §microfactories, biomedical applications, etc., was §the motivation for the current research. This study §describes the design, fabrication and analysis of §such a smart robot a monolithic Micro/Meso Scale §Manipulator (mMM), fabricated from Shape Memory §Alloy powders (NiTi) by means of the laser-based §Direct Metal Deposition (DMD) process.A first §prototype, a functional part of the mMM a SMA §accordion spring type actuator was manufactured by §DMD. The actuator provides a linear movement for the §mMM due to the Shape Memory Effect (SME) property of §SMAs. A new mathematical model describing the phase §transformation kinetics in SMAs and a new analytical §phase transformation function was developed. In the §current work a self-sensing concept was explored §and evaluated in an SMA wire actuator and applied to §the SMA spring based actuator. A new mathematical §model of the motion of the SMA wire- and spring-§based actuators was developed.
