Project On Ultrasound Gesture Detection

2013-01-01T07:25:00.000-08:00

In this project, ultrasound around 24kHz was used to detect movement near an object. Waving a hand or other solid object near the source of the ultrasound (speaker) causes a shift in the frequency of the sound, which is then detected by a microphone. We detected characteristic shifts in frequency to determine whether motion was towards (push) or away from (pull) the microphone. Two modes of visual indication were used to display the results of the motion detection: blinking LEDs and a computer display. With the blinking LEDs, a different color LED would light up according to the direction of motion detected. In the computer animation, the waveform would be displayed on screen along with markings of which parts are pulls and pushes. Sections of the waveform that represent different motions would be marked as push or pull.

Project on Thermistor Respiratory Monitor

2013-01-01T06:51:00.001-08:00

For our project, we wanted to create a solution to a real-world problem. Many biomedical devices, such as commercially available respiratory monitors, are designed for the developed world and require a stable power-supply to operate. We wanted to implement a solution that is adaptable to different environments.

Our device uses several concepts we learned this semester in College. We use analog-to-digital conversions to sample readings from both the thermistor and the battery, pulse-width modulation to generate a signal for the speaker, and timers to switch between tasks. Our implantation also includes various analog circuitry for voltage regulation and signal amplification. Developing a robust and accurate respiratory monitor served to be a challenging, yet rewarding experience.

Project on Integrated Farming System using Microcontroller

2012-09-21T10:18:00.001-07:00

People heavily rely on large-scale farms to grow and ship produce to their local grocery stores. These farms are not always domestic and can be located on the other side of the world. This has become an issue today due to the high transportation costs associated with bringing copious amounts of produce to crowded urban areas as well as to areas that cannot sustain themselves with the local land. Furthermore, the preservatives that are required to allow produce to make it to market inflate this cost. In addition to these economic costs, there are the environmental impacts associated with transporting across these distances.

Integrated Farming System (IFS) Project’s goal is to solve these issues by bringing the farms to these areas through an automated farming system. This system will be enclosed either in its own facility or housed within another existing building. The key is to minimize the amount of real estate required for these systems relative to how much land would be needed by a comparable farm. The constructed model focused on the caring aspects of the overall system. This prototype has proven the feasibility of the system’s design to save space while reducing crop costs.

Integrated Farming System (IFS) would be able to automatically seed, care for and harvest crops without any user assistance. Although not large, the prototype shows that this overall system is plausible as well as expandable due to its modular design.

Kite Power Generation Project – Wind Power from Kites

2012-09-07T08:47:00.005-07:00

The goal of this project was to study the feasibility of using tethered kites to generate power from the wind. Generating electricity using kites instead of wind turbines may have certain advantages, particularly for developing nations. These include generating power at low cost while eliminating certain environmental problems associated with wind turbines. Another advantage is that kites can fly at greater heights than wind turbines can operate. Since wind speed increases with height, and available power is proportional to wind speed cubed, the wind power potential is larger for kites. A literature review was conducted of previous studies of kite power systems. A mechanism was designed to convert the oscillating tether tension caused by the vertical motion of a kite into rotary shaft motion to drive a generator. The mechanism is based on a rocking, balanced beam of 5 meter length attached to a power train and Sprag clutch. The design uses a commercially available sport kite which is 10 meters squared in size. A previously developed MATLAB code was used to model the final system design, and power outputs comparable to small wind turbines were predicted.

Autonomous Underwater Vehicle Design Project

2012-09-06T09:51:00.003-07:00

Autonomous vehicles are increasingly investigated for use in oceanographic studies, underwater surveillance, and search operations. Research currently being done in the area of autonomous underwater craft is often hindered by expense. This project seeks to complete the construction, optimization, and control software development of an inexpensive underwater vehicle. During the course of the project all of the vehicle’s mechanical and electrical subsystems were completed. Propeller-driven primary thrusters using a magnetically coupled drive system were optimized and manufactured. A battery powered electrical subsystem was also designed and installed on the vehicle. A simulation of the vehicle’s control algorithm was developed in MATLAB and several full vehicle tests were conducted.

Thesis on Pulse Oximeter Calibrator

2012-09-06T09:27:00.000-07:00

Pulse Oximeters are standard medical electronics devices used for continuous patient monitoring of arterial oxygen saturation (SpO2) and heart rate (HR). Initial calibration of pulse oximeters is conducted by inducing hypoxemia in healthy human volunteers to obtain blood oxygenation levels as low as 70% and comparing pulse oximeter measurements to that of a reference CO-oximeter.

It was the goal of this project to create a device which would increase the accuracy of the calibration process and potentially set the stage for the elimination of the need for human volunteers. Such a device would also significantly reduce cost and time for companies attempting to bring a new model of pulse oximeter to market. A device such as this, even if it is not used as a substitute for testing on humans, would allow the company the opportunity to test their device before making the expensive commitments involved with FDA testing.

Project On Low Cost Scanning Laser Rangefinder

2012-09-06T08:50:00.002-07:00

As computers and software become more powerful and the area of their application expands, the traditional mouse and keyboard, become more restrictive. Many different devices have been developed to increase Human Computer Interaction (HCI) and this development continues today. The most commonplace Human Computer Interactive device on the commercial market today is the Touch Screen. However, even the touch screen restricts HCI to some extent. These shortcomings and the search to find devices that overcome them were the driving force behind the development of a Scanning Laser Rangefinder for this thesis project.

Project on Wireless message Communicator

2012-09-06T08:28:00.003-07:00

The main function of these devices is to send and receive text messages to and from another device. It is very much like communicating with a walkie-talkie, except with text and smoother communication scheme. We chose this as our final project because we were inspired by the recent technological trend in wireless communication systems. Also, we thought it could be a cool gadget for our cars so that the cars can communicate with each other on a road trip. (Obviously it is not intended for the driver to use.)

Autonomous Smart Trash system Project/Thesis

2012-09-05T10:25:00.004-07:00

We have designed and built a 'proof of concept' prototype for Project Green Stations, an externally funded student group with the following mission statement:

Project Green Stations is all about changing the way people see the environment. Imagine the go-green movement as a brand. Solar panels, Toyota Priuses, and waste receptacles are all points of interaction with your idea of going green.

By designing elegant, simple, and technologically advanced waste bins, we improve one element that affects that perception; one element that almost all students, faculty, and staff at University see every day.

We plan to have the first full prototype manufactured over the summer and ready to go before August. Over the next academic year, we will be looking to further refine the aesthetics and the hardware to best fit our needs. The expectation is by the beginning of the 2013-2014 academic year, we will begin full scale implementation.

Project on CMR Robot Arm

2012-08-30T08:45:00.001-07:00

ur project was mainly designed for the Cornell Mars Rover project team (CMR), which will be using the robotic arm for competition to complete many different tasks in the deserts of Southern Utah.
We created the control systems for a robot arm that is able to use three different end attachments to perform a variety of specified actions, include pushing buttons, scooping up dirt or other items, picking things up with a hook, flicking switches, and taking voltage readings for solar panels. This robot arm uses the Arduino Mega2560 to take in commands from a user to determine which position to move to and what actions the arm needs to perform. It uses four different servo motors to control the four degrees of freedom over the wrist, elbow, and shoulder joints. Also, it controls three end attachments that are attached at the end of the arm: the hook, the scoop, and the control panel interface (CPI). Our controls are also able to open and close the scoop‟s lid servo and turn on and off the brush of the CPI, which has two probes attached that takes the voltage readings.

PID Controller on FPGA for Temperature Control

2012-08-28T10:01:00.002-07:00

The objective of this project was to implement a digital PID controller on an FPGA for a control application. We designed a controller to track and maintain a set point temperature of a water tank with lowest possible overshoot while maintaining maximum possible rise time. Multiple controllers and heaters were used to efficiently control the temperature. We used MATLAB to design our controller and develop a model of our system from experimental data. The heaters were driven using a PWM signal from the FPGA that was amplified using BUZ 73 transistors.
The motivation behind using FPGA to implement a PID controller rather than microcontrollers or DSPs is because it provides a good balance between performance and cost. Using microcontrollers, although they may be cheaper do not provide enough processing power to effectively perform complex calculations in real-time. Digital signal processors can implement complex algorithms quickly but are expensive.

Project On Evolving neural robot

2011-08-26T10:47:00.000-07:00

The Project is to build a mobile robot with a developed neural network such that it evolves to avoid collisions into a circular vertical white wall while traveling at the fastest speed and straightest line possible without human intervention or external computers.

The completion of this project required extensive capacity and application on both hardware and software ends. In constructing the robot, we needed to build the custom prototype board, apply infrared sensors as neural inputs, implement stepper motors for robot motion, and provide a mobile power supply to the MCU. The purpose of these design factors is to allow the autonomous movement of the robot while minimizing the size of our robot, to accurately sense distance and collisions into the white wall of our arena, and to calculate the velocity precisely while providing sustainable torque to move our robot. On the software end, we needed to execute an evolutionary spiking neurons algorithm that interfaced with our hardware. The purpose of this was to integrate a spiking neural model with infrared sensors as inputs and motor speeds as outputs to determine robot velocity and direction. We also implemented the evolutionary model based on assessing random individuals of a randomly generated population through a fitness equation and improving the population by discarding the worst individual in the population with the worst fitness. The fitness equation measured by the velocity of the robot, the direction change, and the amount of activity from sensors.
