Molecular beam epitaxy is a process used for creating thin films of single-crystal materials used for manufacturing semiconductors and nanotechnology structures. During the molecular beam epitaxy process, reflection high-energy electron diffraction capture analysis is utilized to acquire information about the surface of the substrate, including roughness, structural properties, and growth rate. To improve the precision and accuracy of reflection high-energy electron diffraction data, an automation system was created and tested to perform this process, which also increases overall efficiency and safety.

Integrating prosthetics into the lives of amputees is crucial for restoring functionality. Current prosthetics offer limited motion and lack intuitive control, often requiring strict maintenance. We recognize the potential of neuro-prosthetics to address these issues. A proposed robotic arm, controlled by neural signals captured via an electroencephalography cap, aims to enhance prosthetic functionality. This work involves data collection, signal processing, data analysis, machine learning, circuit design, and robotics to demonstrate the feasibility of mind-controlled prosthetics. This innovation could significantly improve the quality of life of amputees, by providing more natural limb movements and intuitive control.

Effective communication with individuals with hearing loss often requires sign language, which can be a significant barrier. A machine learning powered glove system can overcome this barrier by capturing complex hand movements. This system translates sign language gestures into text and speech in real-time, providing a bridge between sign language users and those unfamiliar with it, thus facilitating smoother interactions in various social, educational, and professional environments. These gloves are designed using advanced machine learning algorithms to estimate hand-joint angles and recognize gestures accurately. The system integrates gesture control into digital environments through a computer program, offering feedback via visual and auditory cues. This technology aims to provide a precise, real-time solution for gesture recognition, enhancing user interaction and engagement.

The automotive industry requires rigorous testing of safety components to ensure vehicle reliability and passenger safety. An integrated test system is being developed to streamline the evaluation of automotive and safety components including brake signal transmitters, pressure sensors, wear sensors, electronic stability control modules, and string potentiometers. The system employs a custom-designed test device built around an ARM Cortex-M4 microcontroller and ARM Cortex-A7 running a custom embedded Linux image. It interfaces with peripherals through PWM, analog, and CAN communication protocols, while communicating with a web-based front-end application using Web Assembly, that communicates with a back-end server, both written in Rust, with the ability to save the test results in a text file. The project aims to reduce time and cost associated with field claim evaluations, improve accuracy in identifying faulty components, and enable efficient troubleshooting and root cause analysis.

Robots have been assisting humans for many years, especially in environments where human interventions are not allowed. This work aims to address the gaps in providing dexterous manipulations in current telerobotic systems, where efforts have been more focused on improving commercial haptic feedback devices. Multilayered pressure sensors with polydimethylsiloxane cones and porous structures were designed for applications where teleoperation involves interactions with a broad range of applied pressures. With a haptic system designed using a remotely controlled robotic hand and a piezoelectric actuator, our system provides expanded capabilities in fields such as robotic surgery and space exploration.

The white cane is a tool used by those who have low vision to manually scan for nearby obstacles. To make this process automatic, separate detection and alert modules have been designed and built to detect nearby obstacles. Camera and distance sensor data feed a machine-learning model to infer the presence of an obstacle. The obstacle classification is sent over Bluetooth to trigger vibrations on the back of the user’s hand.

Dedicated systems that transmit analog data around a machine can add cost to the machine’s construction, so a more cost-effective device is needed to move these signals. By making use of the local controller area network (CAN) bus on the machine, a microcontroller was programmed to convert the analog information to digital before packaging the information in the J1939 format for heavy-duty vehicles. That packaged information is then broadcasted every 100ms onto the CAN bus. The microcontroller and other contributing components are mounted to a prototype PCB that transmits the information reliably at a cheaper price than the current system.

Electric vehicles require compact and efficient motors to compete with fossil-fueled alternatives. In-wheel motors are an attractive alternative to conventional electric motors due to their compact form factor. The nature of these motors makes it challenging to implement sensor-based field-oriented control. The goal is to develop a position-sensor system compatible with in-wheel motors and adapt a field-oriented control program to utilize the sensor inputs. This enables the in-wheel motor to operate at a higher efficiency than what is currently available on the market.

Maximum Power Point Tracking (MPPT) is a process that tracks the maximum output power of a solar panel (PV) to optimize usable solar energy efficiency. The MPPT solar charge controller sits between a 12V 20W solar panel and a 12V battery (load). The solar charge controller is operated by an Arduino microcontroller utilizing MPPT algorithms to measure and track PV output voltage and current levels. These levels supply the input to a DC-DC converter, which maintains desired output voltage or current levels for the load. Different MPPT algorithms can be selected within the charge controller to test changes in MPPT efficiency.

Shoe Insole for Gait and Mobility Analysis (SIGMA)

Analyzing gait, or the manner a person walks, is widely used in the sports medicine industry when identifying athletes' unique movements, determining gait patterns, or diagnosing abnormalities. SIGMA was aimed to create a more accessible device that allows users to check their gait from their own screens at a lower-than-market cost with more accuracy and durability. This was achieved using a microcontroller attached to athletic footwear that uses Bluetooth communication to connect to the user’s phone. The final insole prototype provides a network of sensors including pressure sensors, gyroscopes, and accelerometers incorporated into an insole.

Two Phase Inverter Design

Nanogyro has designed a pair of coils that are 90° out of phase and the coils are to be driven by two AC voltages that are also 90° out of phase. Nanogryo has been using a signal generator to produce the two AC voltages, but as the signal’s frequency changes, the output impedance also changes, which is a problem. A microcontroller will be used to produce sine waves at the appropriate frequencies and constant phase output. The digital processing will remove any analog factors affecting the phase of the signals. This project will use a DC voltage to generate the two AC voltages (90° out of phase) with constant output impedances as the frequency changes.
