Accu-Precision is a local manufacturer whose daily machining operations yield hundreds of pounds of metal chips that are collected for recycling. This cumbersome task requires multiple machinists to lift and tip bins into large dumpsters by hand. We have created a machine that automates these actions to reduce handling time and physical strain, allowing machinists to work safely and efficiently.

Obstructive sleep apnea (OSA) is a medical condition where a collapse of the upper airway occurs during sleep in people of all ages. Current diagnosis methods are ineffective in simulating natural sleep to capture the location and pattern of obstructions. The goal of Team 3鈥檚 project is to develop a new method to measure sites and severity of the airway obstruction occurring during natural sleep.

During a bronchoscopy, a needle is passed through the airway to collect tissue samples for cancer diagnoses. Soft robots are relatively novel, yet exemplary in their adaptability in unpredictable environments and increased safety in human-robot interactions. By replacing the distal end of a catheter with a soft robot, we aim to make bronchoscopies safer for patients and easier for physicians.

Our team worked to improve the center-finding process used in the inspection of silicon wafers. The project鈥檚 goal is to find the wafer鈥檚 center to 10-micron accuracy in under 2 seconds. The center is the origin of a coordinate grid that is used to locate defects. The test bench implements a custom algorithm and high-magnification cameras to inspect the wafer profile and log the center position.

Passive monitoring is used to detect events or initiate systems when power is unavailable. Team 18 created a passive, normally open switch for Los Alamos National Laboratory that closes and latches when a magnet displaces sufficiently to be captured by a steel plate. The passive design requires only the energy from a shock event to close, and will not latch in normal transportation environments.
