Any practical model of robotic motion must cope with the uncertainty and impre-cision inherent in real robots. One important model is compliant motion, in which a robot that encounters an obstacle obliquely may slide along the obstacle. In this paper, we start by investigating the geometry of compliant motion in the plane under perfect control and nd a compact data structure encoding all paths ...

Natural organisms have a unique property not yet available in robotics, a self-healing (SH) ability. This powerful biological healing function has inspired chemists to impart similar properties to synthetic materials to create “self-healing materials”. Recent development in SH-polymers made us investigate the potential of using these materials in robotics, and more specifically in compliant act...

Teleprogramming was developed as a solution to problems of teleoperation systems with significant time delays [5]. In teleprogramming, the human operator interacts in real time with a graphical model of the remote site, which provides for real time visual and force feedback. The master system automatically generates symbolic commands based on the motions of the master arm and the manipulator/mo...

Among the different modes of operations allowed in the current JPEG standard, the sequential and progressive modes are the most widely used. While the sequential JPEG mode yields essentially the same level of compression performance for most encoder implementations, the performance of progressive JPEG depends highly upon the designed encoder structure. This is due to the flexibility the standar...

Load-path-based topology optimization is used to synthesize a compliant adaptive aircraft wing leading edge, which deforms in a prescribed way when subject to a single point internal actuation. The load-path-based optimization method requires the specification of a parent lattice. Increasing the complexity of this lattice means the number of parameters required for a complete representation of ...

Previous work in rigid body dynamic simulation has relied on rigid body impact models to model collisions. The well-known models due to Newton, Poisson, and Brach, are each based on a deenition of a coeecient of restitution for rigid body impact. The objective of this paper is to develop a new model that overcomes the deeciencies of these models in frictional impacts and to present a formulatio...

Many robotic tasks require compliant motions, but planning such motions pose special challenges not present in collision-free motion planning. One challenge is how to achieve exactness, i.e., how to make sure that a planned path is exactly compliant to a desired contact state, especially when the con guration manifold of such a contact state is hard to describe analytically due to high geometri...

A grinding robot system is presented in this paper. Active compliant motion control is applied to keep contacting between grinding tool and work pieces and auto surface tracking algorithm was developed to trace the outline of work-pieces. For real implementation of the system, the shape of work pieces are informed through barcode and the piece’s dimension is measured with a laser distance senso...

Reasoning with temporal information1 requires a representation of time considerably more involved than just a list of temporal expressions—which typically define the extent of current time extraction efforts. TimeML is an emerging standard for temporal annotation, defining a language for expressing properties and relationships among timedenoting expressions and events in free text. This paper t...

The use of uncontrolled financial spreadsheets can expose organizations to unacceptable business and compliance risks, including errors in the financial reporting process, spreadsheet misuse and fraud, or even significant operational errors. These errors have been well documented and thoroughly researched by the European Spreadsheet Risks Interest Group [EuSpRIG, 2005]. With the advent of regul...
