In this study, a full-scale prototype of water-based printer’s paint viscosity control device was proposed and conducted. Specifically, novel approach low-cost determination by exploiting the optical sensing method developed to exhibit concept. The feasibility demonstrated measuring accuracy, setpoint deviation estimating its development cost. An accuracy 1.5 cSt standard 1 were recorded compar...

For gaining proficiency in physical human-robot interaction (pHRI), it is crucial for engineering students to be provided with the opportunity to physically interact with and gain hands-on experience on design and control of force-feedback robotic devices. We present a single degree of freedom educational robot that features series elastic actuation and relies on closed loop force control to ac...

Mobile devices differ in many aspects such as screen, keys, browsers, java support and much more. The difficult task designers now face is how to design solutions that take sufficient advantage of specific device characteristics while offering a consistent and similar experience. In this paper we discuss an approach using device categories to tackle this design challenge. Our categorization is ...
