Smartphone Control Of Rc Cars, Weston R. Fitzgerald
Smartphone Control Of Rc Cars, Weston R. Fitzgerald
Electrical Engineering
The smartphone-controlled RC (remote-controlled) car is an inexpensive remote-controlled car designed to be fast and portable. Instead of manufacturing, packaging, and shipping a separate controller, the remote control is implemented in a phone application, which saves time and money in both the design process and the manufacturing process. Utilizing the user’s smartphone is more cost-effective since mobile devices are a common recurrence, and packaging fewer devices results in overall better portability of the product.
This smartphone-controlled car is speedy and intuitive to learn for typical smartphone users. The user can change the car’s speed and direction wirelessly using their phone; …

Dc Treasure Box, Michael A. Derrenbacher
Electrical Engineering
An all in one DC resource would enable electronics students to prototype circuits for labs and projects without the need for the lab equipment present on campus. The labs on campus can be physically far, closed, or overcrowded, preventing students from accessing the equipment. Roughly 75% of upper division electrical engineering students do not own power supplies, with even fewer students owning a source measurement unit (SMU). There is a significant need for a product capable of providing standard lab equipment functionality. The functionally this project provides are positive and negative DC power supplies, 4-Quadrant SMU, analog inputs and outputs, …
Utilizing Trajectory Optimization In The Training Of Neural Network Controllers, Nicholas Kimball
Utilizing Trajectory Optimization In The Training Of Neural Network Controllers, Nicholas Kimball
Master's Theses
Applying reinforcement learning to control systems enables the use of machine learning to develop elegant and efficient control laws. Coupled with the representational power of neural networks, reinforcement learning algorithms can learn complex policies that can be difficult to emulate using traditional control system design approaches. In this thesis, three different model-free reinforcement learning algorithms, including Monte Carlo Control, REINFORCE with baseline, and Guided Policy Search are compared in simulated, continuous action-space environments. The results show that the Guided Policy Search algorithm is able to learn a desired control policy much faster than the other algorithms. In the inverted pendulum …
Real Time And High Fidelity Quadcopter Tracking System, Tyler Mckay Hall
Real Time And High Fidelity Quadcopter Tracking System, Tyler Mckay Hall
Computer Engineering
This project was conceived as a desired to have an affordable, flexible and physically compact tracking system for high accuracy spatial and orientation tracking. Specifically, this implementation is focused on providing a low cost motion capture system for future research. It is a tool to enable the further creation of systems that would require the use of accurate placement of landing pads, payload acquires and delivery. This system will provide the quadcopter platform a coordinate system that can be used in addition to GPS.
Field research with quadcopter manufacturers, photographers, agriculture and research organizations were contact and interviewed for information …
Cal Poly Supermileage Electronic Fuel Injection, Alexander Pink
Cal Poly Supermileage Electronic Fuel Injection, Alexander Pink
Electrical Engineering
Cal Poly Supermileage is a student-run engineering club that builds prototype gasoline vehicles optimized maximum fuel-efficiency. To power their vehicles, the Supermileage team makes use of single-cylinder, 4-stroke, electronically fuel-injected (EFI) gasoline engines. This report details the development, iterative design & test cycles, and integration of an EFI system for the Supermileage club. This project develops an EFI system that interfaces to the most common types of sensors found in the low-power Supermileage-range of engines, including throttle-position sensors, manifold absolute pressure sensors, gear-tooth hall-effect sensors, variable-reluctance position sensors, engine coolant temperature sensors, intake air temperature sensors, and exhaust oxygen sensors. …
Meat Smoker, Rhianna Topp
Meat Smoker, Rhianna Topp
Electrical Engineering
This Senior Project consists of designing and building a meat smoker. The design of this meat smoker incorporates knowledge of control systems, programming, hardware, and materials manufacturing. This smoker is made to allow the user an easy experience of smoking food. The smoker provides the user with a programmable temperature and timer. It also has an automatic wood chip loader as deemed necessary to keep the correct amount of smoke distributed. Lastly, this smoker has an automatic application of the user’s choice of liquid to the meat. By designing a smoker with these capabilities, an untrained person desiring to smoke …

Bridgeless Active Power Factor Correction
Using a Current Fed Push Pull Converter
Jeramie Seth Bianchi
Switched Mode Power Supplies have become increasingly popular for efficient methods of delivering power to an assortment of electronic devices. This thesis proposes a method of using a current fed push pull converter to provide active power factor correction and rectification in a single stage. While most AC-DC converters utilize a bridge rectifier to convert AC-DC and then perform DC-DC conversion, the proposed circuit will utilize its output diodes to perform rectification, thus eliminating the need for a bridge rectifier. This circuit will also …
Solar Panel Tracker, Andrew Hsing
Solar Panel Tracker, Andrew Hsing
Electrical Engineering
This project will be a design and implementation of a polar single axis solar panel tracker. It will have a fixed vertical axis and an adjustable horizontal motor controlled axis. This setup is similar to an office swivel chair. The tracker will actively track the sun and change its position accordingly to maximize the energy output. To prevent wasting power by running the motor continuously, the tracker will correct it's position after 2 to 3 degrees of misalignment. The sensors will compare the light intensities of each side and move the panels until the tracker detects equal light on both …
Automated Basketball Return System, Victor Mendoza, Chris Chamberlain
Automated Basketball Return System, Victor Mendoza, Chris Chamberlain
Electrical Engineering
The project is meant to assist a basketball player in their practicing. The project hangs directly on the basketball rim and automatically rotates to find the player on the court. Once the player is detected, the automated basketball return system (ABRS) stays focused in the direction of the player so that any baskets successfully made will be funneled back to the player. When the player moves from center, IR motion detectors find which direction you moved to and rotates accordingly, until the player is focused in front of the funnel again. If at any time the player is absent from …
