Cyber-Physical Interaction Aware Test Case Generation to Identify Operational Changes
Present day autonomous systems are cyber-physical systems (CPS) that involve multi-dimensional interaction between the cyber machine and the operational environment. One of the key aspects of these autonomous systems is that interaction patterns change over the lifetime of usage. Changes in CPS interaction patterns can be unintentional or intentional...

Statically Stable Hexapedal Walking Robot Platform
There are many obstacles in the way of exploring challenging environments (e.g., the lunar surface's permanently shadowed regions (PSRs)). The rocky terrain, steep inclines, and slick regolith that are typical in these places present challenges for traditional wheeled rovers. For these explorations to be effective, a vehicle needs to have low power,...

Horizontal Self-Burrowing Robot
Burrowing robots are a class of robot that can move themselves in soil for geotechnical site investigation, search and rescue, sensor deployment, inspection, monitoring, and construction purposes. Moving through soil is a challenging problem due to high drag force and complex underground environments. Many organisms adopt well-evolved strategies and...

Bio-Inspired Robot for Tube Inspection
­Tubular structures are commonly used in boilers and heat exchangers. Working under extreme conditions such as high temperatures, large stress loads, hot and high-velocity steam and pressure leads to corrosion, cracks, and stress-corrosion cracks in either the body or welded connections of these components. Regular inspection of these components...

Amphibious Pipe Inspection Robot
Today, robots are designed for use on and in complex terrains and environments. In situations where it is cumbersome and/or hazardous to humans, unmanned vehicles are essential. For example, utility pipe cleaning can cost up to $400,000 per 10-mile segment, with workers scouring miles-long stretches of pipe to remove debris and identify problem areas....

Wave-Interrogated Near-Field Array System and Method for Detection of Subwavelength Scale Anomalies
Anomalies on semiconductor substrates, such as process contaminants, post-polishing substrate fragments, or voids, must be accurately located and identified in order to obtain the cleanliness required by the next generation of integrated microcircuits. While technological advances have reduced the critical anomaly size to less than 80 nm, existing conventional...

Coherent Evanescent Wave Imaging System
Nanotechnology is the study of the control of matter at the atomic and molecular level, and is focused mainly on the creation of materials and equipment to work within that scale. One thing holding back the advancement of this technology is the lack of experimental tools capable of visualizing nanoprocesses in real time across their full range of operation....
