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.

Robotic Vacuum Cleaner Project

2011-08-26T08:20:00.000-07:00

The robotic vacuum is mainly built from a circular piece of foam board.. The robotic vacuum uses a rotating brush underneath the unit to vacuum a carpet as it passes over it. Two stepper motors, aligned across the center axis of the robot, are used to accurately drive the robotic vacuum around a room. Because the body of the robot is circular and the steppers are placed along the center axis, the robot can spin in place in any direction. One free-spinning chair wheel is located at the rear of the robot to keep it balanced.

Project On autonomous Visually Steered Car

2011-08-22T08:44:00.000-07:00

For our final project, we re-engineered a remote control car to autonomously navigate through a track by detecting lanes and centering itself between them as well as detect objects in front of it and avoid collision. The RC car detects lanes through image input from a low-resolution camera mounted at its front. Using an IR distance sensor, the car determines when to stop accelerating once a certain distance between a forward object has been breached. All computations based on sensor data are handled by an Atmel Mega644 MCU. Due to the nature of the input peripherals, especially the camera, this system is extremely time sensitive so that computations had to be optimized as much as possible in order for the car to be able to react and respond with proper movements in real time. In addition, given the limited computational capacity of this 8-bit MCU, our design made use of several computational efficiency strategies.

GSM mobile based car control Project

2011-04-04T09:48:00.000-07:00

A remote control vehicle is defined as any mobile device that is controlled by a means that does not restrict its motion with an origin external to the device. This is often a radio control device, cable between control and vehicle, or an infrared controller. A remote control vehicle (Also called as RCV) differs from a robot in that the RCV is always controlled by a human and takes no positive action autonomously.

One of the key technologies which underpin this field is that of remote vehicle control. It is vital that a vehicle should be capable of proceeding accurately to a target area; maneuvering within that area to fulfill its mission and returning equally accurately and safely to base.

Microcontroller Based Solar Tracking System

2011-04-04T02:35:00.000-07:00

Renewable energy solutions are becoming increasingly popular. Photovoltaic (solar) systems are but one example. Maximizing power output from a solar system is desirableto increase efficiency. In order to maximize power output from the solar panels, one needs to keep the panels aligned with the sun. As such, a means of tracking the sun is required. This is a far more cost effective solution than purchasing additional solar panels. It has been estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of a stationary array . This project develops an automatic tracking system which will keep the solar panels aligned with the sun in order to maximize efficiency.

Project on Pulse Oximeter

2010-12-02T00:59:00.000-08:00

For patients at risk of respiratory failure, it is important to monitor the blood oxygen saturation of such individuals to ensure proper perfusion of blood in their system. Preferably this information should be received on a continuous basis. Both of these objectives can be reached via the non−invasive method of pulse oximetry. This is currently used in hospital/clinical settings, however uses wires which in effect bound an individual to an area. The purpose is to create a clinical diagnostic system which takes a few physiologically relevant signals and transmits them wirelessly to a base station. This project specifically deals with the design of a wireless pulse oximeter for this system. By using the principle of differential light absorption and the assumption that the transmission of light through the arterial bed is influenced only by the relative concentrations of oxygenated and reduced hemoglobin and their absorption coefficients at the two wavelengths, light intensity will decrease logarithmically according to Beer−Lambert’s law.The theory behind our device, hardware design and the experimental results of the system are presented.

Project on Wireless Drawing Device

2010-11-30T06:04:00.000-08:00

For our final project, we want to build a wireless drawing device. The user uses a keypad or a mouse to draw on the TV through a wireless communication medium (RF - 433.92 MHz). The user should be able to move
the drawing pointer to anywhere within the four border lines. One should also be able to draw or erase images on the TV screen. In designing this project, we have two goals - a primary, which is realizable, and a secondary, which is feasible. Our realizable goal is to build a wireless keypad interface with the television. In this interface, we want the keypad to be able to draw and erase on the TV. When we accomplish our primary goal, we shall attempt to achieve our secondary goal: to build a wireless mouse having the same functionality as the keypad. Due to time constraints, we ended up only being able to complete the primary goal. We chose this project because we were inspired by wireless communication technology.

Project on Security Entrance System

2010-11-22T06:15:00.000-08:00

Our security system is a stand alone device that allows access to registered users identified by their magnetic cards.(For this project, "access" is represented by a lit LED, showing how the system could be used to control an external locking mechanism.)The system includes features such as:

Multiple accounts, including Administrator accounts (which can create, modify, or delete the other accounts). The account information is stored in non-volatile EEPROM memory, so that it is maintained even if the system is reset.
A "lock down" of the system when someone tries to gain access by repeatedly swiping incorrect cards.
A 20x4 LCD display to give the user feedback on the current state (such as "Access allowed." or "try swiping the card the other way.") and to prompt administrators for commands. All messages printed to the LCD are simultaneously transmitted to an RS232 port, so that all activity can be logged by a PC.

Project On LEDZEPPELIN HARP

2010-10-28T08:16:00.000-07:00

We resolved to build the poor man’s laser harp, using LED emitters shining across a set of sensors that would notice when we blocked them with our hands. It needed to play tones that sounded sweet and lovely when we needed it for ballads, and hard-edged and techno when we were feeling the dirty nerdy groove. It needed to play several notes at once and listen to a remote control. Most of all, it needed to have a 3.5mm jack so that someday we could live the dream, playing it in that room next to that guy, fog machines and all.

Project on Low-Cost Portable Potentiostat for Biosensing Applications

2010-10-28T07:44:00.000-07:00

A potentiostat is an instrument used in chemical and biological tests that controls the voltage between two electrodes, working and reference, at a constant value. Chemical and biological tests are typically run in a three-electrode system, which includes the aforementioned working and reference electrode as well as a counter electrode. These systems are used to test the electrical activity of certain compounds or microbes, where the electrode acts as either the electron acceptor or electron donor. By monitoring the current and plotting the data against either time (chronoamperometry) or potential (voltammetry), information can be obtained as to the electrochemical activity of chemical compounds and/or microbes. In this project, we will present a design for this potentiostat using the ATMega644, an external digital-to-analog converter (DAC), and a series of operational amplifiers (op-amps). We will utilize the serial peripheral interface (SPI) to communicate between the microcontroller and DAC, the op-amps to process the signal from the DAC and apply a potential to the electrochemical cell, and the internal analog-to-digital converter (ADC) to record the current at the working electrode.

Project On Handheld Ultrasonic Rangefinder

2010-10-24T09:06:00.000-07:00

Our ultrasonic rangefinder is capable of allowing the user to determine his or her distance from an object or wall.

When deciding on what type of project to design and construct, we decided that we wanted to create something that would have some practical use in life. Many groups in the past created video games, but we wanted to be different. We considered issues such as safety, user interface, and ease of use, and came up with the idea of making an ultrasonic rangefinder. A rangefinder can be used in various applications such as a measuring device or an obstacle detection device.

Project On Intelligent Wireless Pedometer

2010-10-24T08:00:00.000-07:00

We have built an intelligent, wearable pedometer. This wireless pedometer can calculate many useful statistics such as the number of steps a user has taken, the distance and the speed the person has walked/run, as well as the number of calories the person has burned. This information is wirelessly transmitted to the base-station, and it is displayed on the PC in a useful manner. This project is in collaboration with the Ambumedics Project with John Belina.Traditionally, pedometers only measure the number of steps a user has taken. Recently, more advanced pedometers include GPS units to calculate the distance a person has travelled, but using GPS substantially increase the cost of the product. Our project uses a low-cost accelerometer to determine the distance, speed, number of steps taken, and calories burned of a user instead.

Project on digital stethoscope

2010-10-22T05:54:00.000-07:00

Our project is a digital stethoscope that displays your heartbeat on any television. It also calculates beats per
minute and alerts you if your rate falls out of a specified range.
At the highest level, the design of our project centers around an acquisition circuit, data processing in two
MCUs, and the output on a TV screen. The first part of the stethoscope is the acquisition unit, which consists of
an actual stethoscope mated with a microphone, and an amplifier circuit. The microphone captures the audible
signal from the body that is acoustically amplified by the stethoscope. After that, we bias and set the gain of the
signal using an operational amplifier so that the ADC on the MCU will be able to pick up the signal. The
analog data will be independently sampled by the two MCUs at a rate appropriate for display on the TV (CPU1) and a rate sufficient to capture the appropriate characteristics of the signal for beat detection (CPU2). CPU2, uses a moving threshold scheme to detect the actual heartbeats, and from that derive the heart rate. Then the signal is blasted to the TV, which also displays pertinent data, such as beats per minute. Additional information is displayed on the HyperTerm. If applicable, a buzzer will sound if your heart rate falls out of a specified range.

Project on Smart House power System

2010-09-24T07:32:00.000-07:00

This project implements a smart algorithm in order to power a house with a photovoltaic, batteries or the power grid. For this project, we worked closely with a research team whose goal is to power a home with minimal power from the power grid. In order to form this smart home, we needed to monitor the voltage and current flow from each of the sources (photovoltaic, batteries, and the grid) and the home. We implemented these current and voltage monitors. The next step was to come up with an algorithm that would determine what source should be powering the house and when the battery should be charged. The final step was to send out data to a home display module so that the data can be analyzed.
