The goal of this project is to design and construct a small modular autonomous car with room mapping and obstacle avoidance capabilities. The vehicle would be useful in cases where it is dangerous for a human to complete a task, or where it is more efficient to have an autonomous vehicle to scout ahead. A key design goal for this project was also to create an inexpensive platform for research into the realm of autonomous vehicles. The car uses lidar technology to create real time 2D room map and detect obstacles. It is programmed to explore rooms and move without human input. We designed the car with a powerful on board computer, enabling it to run complicated programs and operate without the need of an outside computer.

The goal of this project is to develop a low cost and user-friendly device for remote actuation of light switches. We envision a product that is simple to install, easy to control via a remote, and able to function with a variety of light switch geometries. This device can minimize the inconvenience as well as the risk of injuries from turning the light on and off in the dark, especially for elderly people. For this target end user, the device must be simple and require no technical knowledge. Because of this, we have designed a mechanical actuator that will be mounted to the outside of a light switch without the need for tools and controlled by a simple button remote to be kept at the bedside.

Tracking and recording data from high velocity objects is a difficult task, especially when the object is hidden from view during portions of its flight path. When tasked with this problem, the process of solving it began with copious amounts of research into existing and developing technologies. From thermal imaging to radar detection, many options were explored.
Through a rigorous process of elimination to determine the most efficient and cost effective option, induction coils were chosen as the speed sensing device needed to track the desired objects. Normally when current is induced in one of these coils, there is an unchanging frequency of that current. However, when a conductive material passes through the center of a coil, the original frequency changes. This change can be monitored, giving valuable information about an object's location when evaluated over a specific time period.
After hours of bench top testing, several conclusions were made about the production and effectiveness of the induction coils. Chiefly, it was found that the smaller the induction coil diameter the more effective, the object passing through the coil has a larger effect if it does not pass through the exact center, and the "sweet spot" for the number of coil turns falls between 15-25 turns.

Senior design SRS submission:

For our presentation we hope to speak on three of our major groups of our senior design team:
Our first piece involves using programmable logic controllers (PLCs) that are used as the electrical interface between the programming and the mechanical system. Through its own ladder logic program, the code enables the PLC user to dictate when certain relays should be opened or closed for the purpose of turning on and off the vacuum supply and power sources. The PLC then collects data from the pressure transducers so that a signal indicating the next step is sent back to the design. After reading the pressure associated with a certain head, the user can then close a solenoid valve by sending a signal to it via the PLC which will stop the flow of air. With the PLC, the user is in control of where the flow is going to and is consequently, able to modify it through the code. Although the PLC is not a power supply, it does have the ability of processing information by receiving and sending out specified actions, set by the user, to different electronic and mechanical components.
The second piece is based of a tool from a company called pave more. The “pave more” design is a design that picks up bricks from the hack to a separate location to pack them. The design uses separate heads that pick-up bricks using foam that creates a seal on the brick. The heads are connected to a vacuum that allows us to pick up the bricks efficiently. The heads are each on their own spring system that allows them to be picked up at different heights. They are also each on a separate solenoid valve that will sense a missing brick and close the valve to still allow the system to pick up the bricks. The vacuum system is connected to a filter to protect it from the dust and dirt that are on the bricks.

Habitat loss due to urbanization is a primary cause of declining bat populations globally. As a result of this, research has been conducted to review swimming pools as an alternative source of water for bats in urban areas. After collecting data, GIS analysis utilizing color infrared imagery was performed to assess the impact that residential swimming pools have on bat populations.
