High Voltage Waveform Sensor, Nathan Stump

Computer Engineering

The purpose of this project was to build a system to measure the voltage waveform of a discharging railgun. Another group of students had built a railgun system to simulate micro asteroid impacts in low Earth orbit. The only instrumentation available to them was an analog voltmeter attached to the capacitor banks. During the lengthy (30 to 45 minute) charging process, an analog voltmeter was more than capable of measuring the voltage. However, during the discharging process the time elapsed was so short (approximately one millisecond) that waveform data could not be captured. In order to measure power dissipation during …

Sifteo Spice, Ikenga Kenneth Ugo

Computer Engineering

Sifteo SPICE is an application built on the Sifteo platform with the purpose of aiding in the learning of basic circuits. Traditionally, circuit theory is taught to students in two different methods, lectures and laboratory exercises. Lectures focus on auditory and visual learning and are largely passive learning. Lab experiments allow students to physically interact with the circuits, and learn visually through viewing output waveforms from simulators or on measurement devices.[3] The goal of the Sifteo SPICE project is to develop a physical system for virtual, real-time SPICE simulation that mimics the laboratory experience. In Sifteo SPICE, each individual Sifteo …

Caddy: A 2005 Roborodentia Entry With Vision And Path Planning Abilities, Taylor Braun-Jones

Computer Engineering

Roborodentia is an autonomous robotics competition held each year during Cal Poly’s Open House. For the 2005 competition, robot entries needed to navigate a maze searching for three randomly placed golf balls, collect them, and then deposit the balls in the “nest” at the end of the maze. A newly added aspect for the 2005 competition included two bonus balls that were placed on a platform behind the wall in two predetermined corners of the maze.

Caddy is a robot that was entered into the 2005 Roborodentia competition. Caddy included a vision system that allowed searching for balls down untraveled …
