Fitness Plug, Evan Lee Ashley
Fitness Plug, Evan Lee Ashley
Computer Engineering
My parents only allowed me to play videogames or watch television for a certain number of minutes or hours per day. By limiting screen time, they encouraged me to be active and find other things to do outside of television or videogames. The Fitness Plug aims to do both by converting time exercised to entertainment time; you can only watch television or play videogames for as long as you have exercised.
Rchex: A Radio-Controlled Hexapod, Dominique Sayo
Rchex: A Radio-Controlled Hexapod, Dominique Sayo
Computer Engineering
rcHex is a radio-controlled hexapod with 18 degrees of freedom, capable of positional and rotational body adjustment as well as omnidirectional travel at variable speeds using three common gaits. Its general-purpose design accessible to hobbyists makes rcHex an platform for further development, whether it be experimentation in advanced robotic movement or retrofitting sensors to utilize technologies such as computer vision and artificial intelligence. This report explores some of the design intricacies of hexapod movement, including gait sequencing and the application of inverse kinematics to multi-jointed limbs.

Autonomous Butter Robot, David Chau, Michael Hegglin
Computer Engineering
Don’t you wish your butter would come to you? Well now it can with the patented Michael and David butter robot! Based on an idea from a TV show, our team set out to see if a similar robot was possible to make in real life. The objective was simple. Can we make a small table sized robot that can bring a person butter using image detection software? With that question in mind we set out buying our components. We wanted to keep it small, so we looked up devices that could do simple image processing and from there we …
Otter Debugger, Keefe Johnson
Otter Debugger, Keefe Johnson
Computer Engineering
This project is a debugger and programmer for the OTTER CPU, the implementation of the RISC-V ISA used by Cal Poly to teach computer architecture and assembly language in CPE 233/333 and usually implemented on the Basys3 FPGA development board. With this tool, students can quickly program their OTTER with a new/revised RISC-V program binary without resynthesizing the entire FPGA design. They can then use the debugger from a PC to pause/continue/single-step execution and set breakpoints, while inspecting and modifying register and memory contents. This enables real-time debugging of OTTER projects involving custom hardware such as a keyboard and VGA …
Otter Vector Extension, Alexis A. Peralta
Otter Vector Extension, Alexis A. Peralta
Computer Engineering
This paper offers an implementation of a subset of the "RISC-V 'V' Vector Extension", v0.7.x. The "RISC-V 'V' Vector Extension" is the proposed vector instruction set for RISC-V open-source architecture. Vectors are inherently data-parallel, allowing for significant performance increases. Vectors have applications in fields such as cryptography, graphics, and machine learning. A vector processing unit was added to Cal Poly's RISC-V multi-cycle architecture, known as the OTTER. Computationally intensive programs running on the OTTER Vector Extension ran over three times faster when compared to the baseline multi-cycle implementation. Memory intensive applications saw similar performance increases.
Wine Sampler, Lance L. Litten
Wine Sampler, Lance L. Litten
Computer Engineering
Quality testing is an important part of the wine industry. Without proper quality control, thousands of dollars could be wasted on bottling and recalling hundreds of gallons of wine. Due to this, labs are set up that collect wine samples from the tanks in a wine production plant and test them. A big part of this testing is determining exactly what tanks need to be tested and what tanks are at risk. My project aims to help automate this task by collecting data from the tanks wirelessly and keeping track of simple indicators such as pH and temperature. Automating this …

Room Management Web Application And Movement And Temperature Sensors, Visalbotr Chan, Huy Anh Duong
Computer Engineering
There are three main parts of this system: micro-controller, database, and website. Micro-controller detects motion of people walking in and out and It also measures room temperature and humidity in a confined space then updates collected data to the database. Our system’s database contains 6 main columns: room number, room capacity, number of students, temperature in Celsius, humidity in percent and date created. Finally, this database is queried by the website to display the information on the webpage. Users could also navigate on our site to check the most and least occupy rooms, and they can also search for a …
Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System, Luke Martin Liberatore
Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System, Luke Martin Liberatore
Computer Engineering
The Tiny Disco is a WiFi based concert system, featuring improvements on popular “Silent Disco” concerts. Rather than being tied to compression and bandwidth restrictions present in traditional silent disco systems, the Tiny Disco system can deliver 320kbps+ audio quality, and allows listeners to bring their own headphones, further lending to the high quality audio experience.
Tiny Disco uses a Raspberry Pi as the audio server, and Espressif ESP32 microcontrollers as audio receivers/clients. The Tiny Disco is primarily geared toward smaller concerts and niche events where audio quality is valued, though due to its WiFi-based architecture, it can be expanded …
