Crowdsourcing is gaining attention from companies looking for a low-cost, scalable labor force as well as from researchers seeking to leverage human intelligence and study human cognition. Much current crowdsourcing research is related to discovering methods for obtaining high-quality, trustworthy output from the crowd. One element of quality crowd-generated work is repeatability; ie, results a...

This paper presents a new 3-D design of a discretely-actuated robot manipulator powered by binary actuators. Binary actuators have two stable states, which are, for example, closed (0) and open (1). Major benefits of this kind of discretely-actuated manipulator are repeatability, relatively low cost, and no need for feedback control. In addition, hyper-redundancy allows tasks to be performed ev...
