Hydraulic-Based Spherical Robot

Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...

Megahertz-Rate Molecular Tagging Velocimetry

In recent years, a large number of Lagrangian-based optical velocimetry techniques have been developed that are known, collectively, as either flow tagging velocimetry or molecular tagging velocimetry. In either case, the method is based on the use of an optical resonance to “tag” a pattern into a...
