Design and Control of a Soft Robotic Ankle-Foot Orthosis

For physical therapists working with patients with foot and ankle injuries, it is imperative that they have mechanical help with the rehabilitation process. However, existing solutions are cumbersome and stationary. To combat this problem, researchers are engineering a device using light-weight, flexible soft robotics that a patient would wear over the foot that would aid

Lowering Image Sensor Reconfiguration Latency on Android

Mobile systems would benefit from the ability to make a tradeoff between image resolution and power consumption when doing vision tasks. While less resolution lowers task accuracy it also saves system power. Currently, resolution changes are a slow process taking over 200ms while also dropping frames. However, researchers propose a system to lower that latency

Octopus Arm Muscles in Relation to Arm Use for Bioinspired Robotics

The objective is to study the musculature of Octopus arms for use in Bioinspired Robotics.  Previous literature presents the idea of uniform muscle layering. The lab has found this not to be the case as the muscle layers change proximal to distal (base to tip). Correlations between the transverse and longitudinal muscle layers indicate specialized

Battery Decay Rate and Life Cycle in Lithium-Ion Polymer Batteries

The objective of the research project is to determine the baseline life cycle and battery decay rate of a lithium-ion polymer battery in drones. The first experiment had the drone statically hovering, which simulated a uniform power draw for a baseline measure. Continuing research tested the battery decay by performing three uniform experiments to completely

Adaptive Sampling

Modern smartphone cameras capture high-resolution images, containing millions of pixels. However, computer vision tasks operate effectively on images of much lower resolution. The research team seeks to implement an adaptive sampling block within the imaging pipeline on an FPGA. The adaptive sampling block can utilize key information from the prior image to remove unimportant pixels

The Dynamic Reconfiguration of Solar Cells on Spacecrafts

Currently, spacecraft solar arrays can degrade from 20-50% in power producing capability over a 15-year mission, making it unfeasible for current state-of-the-art designs to access the full power available from the solar array. The objective of this research is to elongate the duration of spacecraft missions by creating a gallium nitride (GaN) switch that will

Development of MOF/Graphene Aerogel Composite for Ammonia Adsorption and Sensing

Metal-organic frameworks (MOFs) are a class of crystalline materials which have properties useful for gas separation, purification, and storage. While these MOFs can be extremely selective with the molecules they adsorb, the desorption processes can be slow and inconvenient. The objective of this project is to create and study a MOF/graphene aerogel composite which is

Scaling a Helicon Plasma Thruster for CubeSat Applications

Electric thrusters provide high propellant efficiency to give spacecraft the capability of large maneuvers at the cost of a low propellant mass. This project aims to design a compact helicon thruster of an optimized maximum thrust, exhaust velocity, and efficiency on a small scale that can be used for CubeSat applications and other small spacecraft

Measuring the Heat of Combustion of Biomass Pellets

Pellets have higher density and greater hardness than other types of biomass which enable easier transportation and storage. This research aims to investigate the amount of energy released and ash determination after combustion. Pellets from different types of crop residue will be experimented on using an oxygen bomb calorimeter and an ignition unit. The heating
