PersonalSoundtrack: Greg Elliott
Location: University of California, Irvine: Irvine, CA
PersonalSoundtrack, a tiny wearable computer, detects your walking or running speed and plays songs from your music library that match your pace. Song speed is adjusted in real-time to match subtle variations in your gait, while larger, deliberate pace changes cause the device to change songs. You simply put it on and begin moving; that's it.
Most computational devices require the user to adapt to the machine. PersonalSoundtrack offers, instead, a symbiotic relationship: both human and machine actively adapt to each other in real-time. The 'interface' is one's natural gait. There is no optimal or pre-defined experience, encouraging meandering, wasting time, and loitering.
This project has been demonstrated at several shows and featured in several magazines.

University of Deusto, Spain
Juan Ignacio Vazquez is doing research about embedding Semantic Web technologies into Ubiquitous Computing platforms in order to create more intelligent, perceptive and reactive devices. The prototypes are called smobjects (smart objects): intelligent agents that exchange semantically annotated information in order to create a shared knowledge space about the environment. Smobjects can spontaneously discover each other and be configured with high-level behaviors using appropriate vocabularies and ontologies.
One of the prototypes is a talking plant integrated in the environment, aware of existing conditions (e.g. dangerous or flammable materials) alerting the user about any existing hazard. Other prototype is a weather-aware umbrella that discovers surrounding sources of weather data (such as a rain sensor or an Internet connection to download a weather forecast), blinking if the user intends to leave home without it (if needed).

We have ported Player to Gumstix, and are developing controller code and matching Player drivers for the Robostix interface board. We will release our code and designs under GPL and Creative Commons licenses as soon as possible.
- Chatterbox interview - an interview with Professor Vaughan about his "swarm of chatterboxes" - his gumstix-driven robots.
The goal of the FlockBots project is to produce a small (7-inch), differential-drive mobile robot crammed with functionality for about $800. The robot includes a Gumstix 200bt, servoed camera, gripper, encoded wheels, five range finders, touch sensors, and I2C. The robots are intended to be a major step up in capability from "hobby"-type robot kits running off of PIC controllers, etc., while being inexpensive enough to construct a swarm on a budget.
We have published the specification, software, vendor information, and extensive construction details in the hope that others will be able to build similar bots without having to reinvent the wheel. Almost all the robot parts are COTS and provided software is free open source. We invite you to contribute to the website: suggest design changes, revised software, or include a link to your own swarm robotics page.
AIT Dept. at George Mason University
During the 06-07 academic year, students in the AIT Dept. at George Mason University in Manassas, VA built a Gumstix based payload flown on a radio controlled helicopter to do mapping, video and networking. This is a project for a class on Information Defense Technologies. More on the mission can be found on Dr. Marchant's website and on the class wiki. During the Fall 07 term, students will integrate a Gumstix with an iRobot Create to produce a surveillance UGV. (Can it be a coincidence that GUM is an anagram of GMU?)
Penn State RCOE: University Park, PA, USA
Our group is working on Rotary-Wing UAV. Recently we use gumstix 200-bt and robostix instead of early used PC/104 system. the new gumstix system is much smaller and highly integrated, which is ideal for aerospace special demand in weight. the platform is still under development and by now everything looks pretty good. latest news will be reported on our project page.
CalPoly Spacecraft Attitude Dynamics Simulator
Aerospace Engineering students at the California Polytechnic State University, San Luis Obispo, CA, are developing a relatively inexpensive spacecraft attitude dynamics simulator. The simulator platform rests on a spherical air bearing, which allows full rotation of the platform about its yaw axis, and partial rotation about its roll and pitch axes. A set of four reaction wheels in a pyramidal formation are used as momentum exchange devices to provide three-axis control authority. The platform's motion is measured by accelerometers and laser-ring gyroscopes, and a webcam-based star tracker provides attitude measurements relative to a simulated star field.
In the platform's current configuration, two Waysmall 400xm-bt boards relay reaction wheel motor states, IMU data, and star tracker images via Bluetooth to an offboard PC, which processes the data and returns reaction wheel commands. While the processing could potentially be done onboard the platform, interfacing the platform with Matlab on the offboard PC will eventually allow students to rapidly develop control schemes using Simulink and observe their real-time performance.
The North Carolina State University [http://www.ncsu.edu/stud_orgs/ar Aerial Robotics Club is developing a UAV autopilot module for the GumStix, called FlightStix. The FlightStix may be used by ARC to compete in the AUVSI international aerial robotics competition. The system is intended for use in medium-sized fixed-wing (15-50 lb) and rotor wing (5-15 lb) unmanned aerial vehicles. The system's sensors and outputs include:
- 10-channel independant servo-type PWM input and output
- 3-axis gyroscope
- 3-axis accelerometer
- 3-axis magnetometer
- Ultrasonic altimeter
- 2 differential-pressure transducers (for pitot/static and barametric altitude)
The hardware used to develop FlightStix consists almost entirely of donations from various electronics manufacturers, including GumStix, Inc.

ZeeRO mobile robot
The Robotics Research Group, Technical University of Cluj-Napoca, Cluj-Napoca, Romania has created a sub-1000 Euro mobile robot, which can be used as a standard research platform in their labs. ZeeRO (Zee RObot - see Snatch, the movie) is a differential drive, low cost mobile robot, using a Gumstix 400bt, 2 "clustered" Acroname Brainstem boards (although one of them is just for expansion purposes right now), 4 x SONAR, 2 x IR, 1 x pyroelectric sensors, together with a CMUcam2 servoed.
We ported the Player platform to Gumstix, and use Javaclient to control our robot's complex algorithms. We're experimenting a lot with neural networks, intelligent agents, and D*-like dynamic navigation algorithms.
In order to control ZeeRO from Player, we wrote a new driver (zeero) and modified some existing ones (such as the cmucam2 driver). The zeero driver is providing the following interfaces to the client library: ^- position2d (for the servos)^ ^- sonar (for the ultrasonic sensors)^ ^- ir (for the infrared detectors)^ ^ - aio (for the pyroelectric sensor)^ The cmucam2 driver (thanks to Richard Vaughan for the original driver) provides a blobfinder, a ptz and a camera interface to the robot. Schemes, pictures, ideas, explanations, and most importantly, source codes are provided on the ZeeRO web site.

- Montevideo, Uruguay.
This project belongs to three students of electrical engineering and to the Institute of Electrical Engineering, Faculty of Engineering, Universidad de la Republica.
Its our degree project and consists in designing, constructing and validating an autonomous flying vehicle. The main purpose was to develop a platform for further investigation in the area so it needed to be scalable. Due to limited budget, the construction was done entirely by the group which held to time problems.
The system includes:
- 1x Gumstix connex 400xm
- 1x Robostix
- 1x Tweener
- 3-axis accelerometer (2x ADXL320)
- 3-axis gyroscope (3x ADXRS300)
- GPS (1x GPSstix)
The system is deployed and landed manually and switched in auto-mode using a free channel from the R/C radio. It's supposed to follow a determined path (pre flight configured). Right now we are in the final stages, only resting the interface for tuning the PID loops. All the software is open source based, and very special thanks goes to all the contributors on the gumstix mailing list. You can visit a blog of the project (Spanish) to see some of the work and news, an english version and more complete webpage will be available when time permits it.
Aberystwyth University Department of Computer Science is using gumstix in several sailing robots. These are being used to autonomously perform oceanography and to compete in the Microtransat Challenge a transatlantic autonomous boat race.
Currently 3 boats are using the gumstix:
- "The ARC" - A 1.5m long plywood boat. Uses stepper motors to drive two sails and the rudder. Originally a robostix was used to do this, with a wifi enabled gumstix (connex 200 with CF wifi card) being used to reflash the robostix over i2c. This has now been replaced with a single gumstix controlling a series of GPIO14 chips to drive the steppers as well as some DS1621 temperature sensors.
- "Beagle B" - A 3.5m long fibre glass boat based on an off the shelf dinghy. This uses two linear actuators to drive the sail and rudder, these are controlled by MD22 motor controllers over I2C from the gumstix and a GPIO14 is used to read the feedback potentiometers on each actuator. A rowind ultrasonic windsensor, GPS and PG-500 compass are all connected to serial ports on the gumstix, GPIO lines on a breakout-gs are used to switch transistors which control the power to each of these. Communications is provided by an 802.11b compact flash card configured to behave as an access point as this was found to reconnect with greater ease than using ad-hoc mode. This boat is currently being fitted out to perform oceanographic monitoring and the control system is being redesigned to incorporate two gumstix, one for robot control and another to control the scientific instruments.
- unamed boat - A 2.75m long dinghy intended to cross the atlantic in the Microtransat Challenge. An off the shelf tiller pilot controls steering and is connected to the gumstix via a serial interface. Another motor controls the sail using an MD-03 i2c controller. Comms are to be provided with an Iridium satellite phone.
This project consists in hardware and software development for a little UAV (Unmanned Air Vehicle) for information acquisition in emergency areas.
Distinctive aspect of this work:
- Gumstix board for ground communication and high level operations
- Robostix board for hard real-time operations and motors driving
- robotic technology application to maximize vehicle autonomy and reduce operator job
- controller synthesis with validation by simulation
Overall vehicle mass is 0.5kg, max diameter is 79cm. Structure, motors and rotors are taken by DraganFlyer V Ti, a quad-rotor platform; avionics were completely replaced.
Project is developed in the SIED lab (Intelligent Systems for Emergencies and Civil Defense) of Department of Computer and Systems Science "Antonio Ruberti" in collaboration with the Department of Mechanics and Aeronautics of University of Rome "Sapienza".

Pegasus High Altitude Balloon Project
By James Coxon - Project Website
The Pegasus High Altitude Balloon project is a UK based amateur student run project that involves launching payloads to "Near Space" (between an altitude of 60,000ft (20km) and 325,000ft (99km). This is achieved through the use of helium weather balloons which are designed to burst at a certain height and then the payload returns to earth via parachute. We have launched 3 payloads:
- Pegasus I - (Gumstix basix + waysmall HWUART board) - reached an altitude of 20295m
- Pegasus II - (Gumstix connex + waysmall STUART + CFstix) - lost
- Pegasus III - (Gumstix connex + GPSstix) - reached altitude of 19495m
- Pegasus IV - Under Construction
Features of gumstixs used:
- GPS (serial, compact flash and onboard)
- Interfacing with mobile phones (gnokii)
- Interfacing with radio (Aerocomm 868mhz radio modems + 434mhz beacons)
- Using GPIOs to trigger camera shutters + cutdown circuits
By Steve Falco
I used a gumstix with a netCF and GPSstix to build an NTP stratum 1 timeserver. I have an LCD display, showing time of day, location, satellites in view, etc.
A number of mods were done to the GPSstix. I added a pulse-per-second interrupt and a GPS reset circuit. I also hacksawed the 60-pin connectors off a tweener so I could superglue the tweener to the GPSstix (and white-wire it to the uart).
I also bisected the netCF with a hacksaw, so I could bulkhead mount the ethernet connector part of the board (and yes, I am a little bit crazy...).
Anyway, I'd be happy to make the code and schematics available if anybody wants to build something similar. Some pictures and a bit more info here: NTP Clock
"Homebrew" mobile phones are being developed using a Gumstix at their core. The "Silicon Valley Homebrew Mobile Phone Club" (SVHMPC) is a collection of enthusiasts centred on developing such phones.
