Our project is to design a remote and self-controlled vehicle that is as energy-efficient as possible. This will be accomplished using technologies and principles employed in the design of full-sized hybrid automobiles. The design will include components that consume no more than the application requires (LED lights and other high-efficiency electronics) as well as regenerative techniques to reuse power expended in operation.

The vehicle will be actively controlled by a reprogrammed wireless router, running a custom Linux install - in essence, this will allow complete control over the system software and connected peripheral sensors and devices within the system. These peripherals will include temperature, speed and optical sensors.

The vehicle will be self-controlled by software responding to external data collected by sensors on the vehicle. Specifically, the primary source of power will come from a solar panel mounted on the vehicle. Optical sensors will determine the optimum location within a certain range to collect light energy and software will move the vehicle to that position.

Project Objectives:

Minimum: A solar-powered, router-controlled RC vehicle.
Target: A self-controlled software-sensor interface with hybrid/regenerative techniques for energy recapture and reuse.
Optimal: A vehicle that consistently consumes less energy than it is able to harvest, with secondary systems (GPS, Energy Savings Calculator, self-defense capabilities, battery charger, bells, whistles) powered by the excess energy. A variety of harvested energies (in addition to solar) and energy recapture techniques.

A long-term research project is currently in progress to perform subterranean mapping using co-operative helicopters holding a long wire acting as an antenna.

Our team's objective will be to create a generic communications interface board and a generic communication protocol to achieve a modular avionics system. The goal for our capstone project is to use this avionics system and a simple LTI controller & model to get a model RC helicopter to hover autonomously (or augmented control). If time permits, we would like to perform data logging for system identification, which may be used in a sophisticated compensator and estimator.

The helicopter has 4 main components (all commercial parts) which we will try to get to communicate with each other:

Flight computer (compensator & estimator)
Inertial Measurement Unit (IMU) (Position and Orientation sensor)
GPS (Position sensor)
RC receiver (Feed forward or reference input) and RC Servos (Actuators)

Due to the rapid advancements in the digital signal processing technology particularly in the audio realm it is now possible to implement sophisticated digital sound effect in real time. We proposed to develop the Kabuki 2000 "Real time music modulator," which could be used to implement finely-tuned effects in live stage performance. Echo, Reverb, Pitch Shifting, and Granulation, these are merely a few audio effects that the Kabuki 2000 will be able to offer. The Kabuki 2000 will be able to organize a preset list of effects that aid in musicians live stage performance, and have a user-friendly interface to move through and tweak effects. The kabuki 2000 will be cased in metal or plastic, which the user will be able to mount it in various situations (table, floor, rack). The kabuki 2000 will be easily connected to a PC through a USB port, to download various preset audio effect play lists. The device will illustrate various equalizer bars on a LCD touch screen where the user will be able to control the intensity as well as modify specific parameters of each audio effect. The interface, which is the most elaborate portion of the project, will consist of several foot pedals, knobs, and viewable screens, to allow the user maximum control.

We have a goal of building a paintball gun with video and sound that is controlled over a computer network. Using data obtained from the wireless signal one can aim and shoot the paintball gun at a specific target. The range of motion for the device will be 360 degrees of horizontal motion and 60 degrees of vertical motion. This device will be useful for recreational, security, and military purposes. In the security and military fields this device will eliminate the threat to a human life, where the user can be at a remote location protecting the area in which the device controls. Recreational purposes include the usage at paintball arenas for added obstacles.

We are designing a PC Oscilloscope for our capstone project. The design objectives for our oscilloscope are:

Probe functions as contact from DUT to oscilloscope.
Signal goes through probe into the signal conditioner.
The signal conditioner readies the signal for the ADC
The Analog/Digital Converter converts signal it to digital..
The FPGA then takes that data and places it into memory.
Once memory is full, data is sent to the USB controller (handled by the fpga) via UART.
The USB control sends data to the PC.

There are two ways the scope could be used.

Trigger based
Free-flow

For trigger base, via software we tell the FPGA when we want it to trigger (at what voltage), when the data received hits that value, the process above starts and data is sent to the memory.

For free-flow as soon as the ADC passes valid data to the FPGA, we begin passing the data to the memory and to the USB in a loop until via commanded to stop.

Right now about 10% of the energy our community uses is renewable energy. What if we wanted to increase this percentage to 30%? With only 10%, if there is a cloudy, not windy day the traditional power plants can make up the difference. However when relying on renewable energy to provide 30%, a cloudy, not windy day can become a big issue. So, our project is to use renewable energy sources to power a simulated city that deals with 30% of Boulder's energy consumption. Obviously we have scaled this down to actually make our working prototype. The idea is that when there is a surplus of renewable energy, we want to store that energy for the times in which there is insufficient renewable energy. We plan to store this energy one, or possibly two, ways. First is to pump water to the top of a hill. The other way is to store the energy in batteries. Our city will be made from LEDs and the buildings of the city will be made of Legos or wood. We plan to have solar panels, wind turbines, and a storage bank of energy. If possible, we would like to model other things such as an electrically powered transportation system by having a miniature car drive around the city.

The stimulus in our project is the weather, primarily sun and wind. The intelligence of our project lies in sensing the amount of power each renewable source is producing. Our response is taking the data received and deciding from what source to draw the power in order to power the city. If there is a surplus, the excess power will be sent to the appropriate device in which we have decided to store the energy.

We will display on a nearby monitor the power consumption and generation of each source as time goes on. This allows one to see specifically what is happening at each source, instead of just watching the city react to the different situations.

Our project is to design a vehicle controlled remotely by a handheld touch-screen computer. The touch-screen will display a map of an area and the user will be able to draw a path on it that the vehicle will attempt to follow. If the vehicle encounters any permanent obstacles that it cannot pass along the way, it will manuever around the obstacle and update the map on the touch-screen to include the new obstacle. In addition, the touch-screen computer will display the current position of the vehicle on the path, distance traveled, distance remaining, and estimated time of arrival. The position of the vehicle will be determined by measuring the distance between two beacons at the corners of the map and the vehicle.

The touch-screen computer will be designed on a Hewlett-Packard iPaq pocket PC. It has a handheld version of windows on it, which will allow us to build a GUI in C⁺⁺. The iPaq uses Bluetooth to communicate wirelessly. Bluetooth is range-limited to 30ft, but uses very little power compared to longer range wireless technologies.

The vehicle will be battery operated, so we will aim to make its power consumption as low as possible. We will need to mount radar sensors on all sides of the vehicle to give it a 360-degree sense of nearby obstacles. An onboard FPGA will control vehicle to iPaq communications, obstacle avoidance, and regional positioning.

With the advent of information technology revolution and convergence, people are increasingly devoid of human relations. Consumer electronics enable individuals to access any information and media on demand without any human interaction. Ironically, we are witnessing isolation of the individual in this continually shrinking global village.

Our project will be a high fidelity base-station, which will allow personal enjoyment without losing the connection to the local working network. Leveraging the popular demand for MP3 players and popular culture of listening to songs while doing daily chores, the vision is to allow broadcasting not only high definition music, but also announcements to the same members or employees. This has the added benefit of skipping cell phone carrier networks and also not being hooked to a computer with Internet access for instant messages. MP3 songs can be bought in bulk-discounted prices for consumption within the local network.

The design will consist of a base-station and some number of receivers (headphones and/or speakers) which all receive broadcasts independently. The base-station will have stereo audio inputs, a microphone input for real time MP3 encoding and removable media for previously encoded MP3 files. There will be onboard memory, which will allow for the storage of multiple songs or specific sound bytes. We will use the unregulated 2.4Ghz wireless band, which will allow for short-range, omni-directional transmission of signals.

The receivers will include the ability to select desired channels as well as volume control. The user interface will consist of a color touch screen for quick and easy user control.

The project we are proposing is a structured light 3 dimensional scanner. The technique will consist of a laser line projected onto an object that is sitting on a rotating platform. A camera will record images at a slightly offset angle from the laser in order to use a process called triangulation to determine how far from the camera the laser is shining. The platform will rotate by a motor that is controlled by a digital signal. The whole system will be controlled with an embedded system consisting of an FPGA to move the motor and coordinate the images taken with the position of the platform. Some data can be processed directly in the FPGA, such as determining which pixels in the RGB image are laser light and converting the image to black and white. The black would be where the laser is shining and the white where it is not. The black and white data would be sent to a computer workstation, and using algorithms we write, would be converted into three dimensional data points. This data will then be sent to a program like MATLר and constructed into a 3D image.

Since the beginning of soccer, referees have made mistakes in declaring a close goal where the ball has not entirely passed the goal line. This created a lot of controversy during important matches. After much discussion and protests about the need to improve officiating in soccer games through the use of technology, team INTERNATIONAL decided to launch the goal-line technology that will be able to determine whether the ball has fully crossed the goal line or not.

The first part of our project will involve implementing a beside-the-goal camera that is linked to a computer. The data and pictures from this camera will upload to a computer which will then display the goal frame on the screen so the user can determine whether the ball passed the goal line or not, similar to the technology used in tennis to determine if a ball is in or out.

In the second step of our goal-line technology, we will be focusing on building a launcher device that will be able to shoot a ball anywhere at the goal using a controller. The device will be used to launch the ball moving it both vertically and horizontally. Once this is fully functional, we will create a semicircular rail on which the launcher moves, changing the position from which the ball is launched.
