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...

Briefs: Imaging

Today's glass-based lenses are bulky and resist miniaturization. To address the problem, two different imaging methods — a type of lens designed for nanoscale interaction with lightwaves, and robust...

Briefs: Electronics & Computers

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Briefs: Imaging

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a...

Briefs: Test & Measurement

A limitation of today's ultrasound devices is that they are difficult to use on objects that don't have perfectly flat surfaces. Conventional ultrasound probes have...

Briefs: Mechanical & Fluid Systems

The wetting behavior of a liquid on a solid surface is a phenomenon of significant practical importance. The angle of liquid-to-solid contact is important in areas such as adhesion,...

Briefs: Sensors/Data Acquisition
