Magnetically tunable micropillar arrays with uniform, continuous and extreme tilt angles for real-time manipulation are reported. We experimentally show uniform tilt angles ranging from 0° to 57°, and develop a model to accurately capture the behavior. Furthermore, we demonstrate that the flexible uniform responsive microstructures (μFUR) can dynamically manipulate liquid spreading directionali...

Research in autonomous mobile manipulation seeks to develop mobile robotic systems that autonomously perform manipulation tasks in unstructured environments. Such robotic systems could have a profound impact on many application areas of societal, economic, and scientific importance, including domestic assistance, healthcare, flexible manufacturing, automated supply chain management, planetary e...

The flexible endoscope is increasingly used to perform minimal invasive interventions. A novel add-on platform allows single-person control of both endoscope and instrument at the site of intervention. The setup changes the current routine of handling the endoscope. This study aims to determine if the platform allows effective and efficient manipulation to position the endoscope at potential in...

This report presents the design and implementation of LENS, a program information manipulation framework that that supports focused program investigation by providing a standard and easily accessible interface to access program information, based on the programs low-level control structure. LENS maintains version and configuration attributes for the data, enabling flexible comparisons across ex...

The use of the Yager’s OWA operators within a flexible querying interface is discussed. The key issue is the adaptation of an OWA operator to the specifics of a user’s query. Some well-known approaches to the manipulation of the weights vector are reconsidered and a new one is proposed that is simple and efficient.

Force control is very important for many practical manipulation tasks of robot manipulators, such as, assembly, grinding, deburring that associate with interaction between the end-effector of the robot and the environment. Force control of the robot manipulator can be break down into two categories: Position/Force Hybrid Control and Impedance Control. The former is focused on regulation of both...

We report on the electrical manipulation of single- and double-stranded oligodeoxynucleotides that are end tethered to gold surfaces in electrolyte solution. The response to alternating repulsive and attractive electric surface fields is studied by time-resolved fluorescence measurements, revealing markedly distinct dynamics for the flexible single-stranded and stiff double-stranded DNA, respec...

In this paper, a novel flexible robot system with a constrained tendon-driven serpentine manipulator (CTSM) is presented. The CTSM gives the robot a larger workspace, more dexterous manipulation, and controllable stiffness compared with the da Vinci surgical robot and traditional flexible robots. The robot is tele-operated using the Novint Falcon haptic device. Two control modes are implemented...

We define a class of tangible media applications that can be implemented on consumer-grade personal computers. These applications interpret user manipulation of physical objects in a restricted space and produce unlocalized outputs. We propose a generic approach to the implementation of such interfaces using flexible fiducial markers, which identify objects to a robust and fast video-processing...
