River current research

A team of researchers from the University of California at Berkeley trying to learn more about the river currents in the delta.

The researchers are working with propelled 4-foot-long submarines and floating drifters equipped with GPS-receivers for positioning, GSM-modules for communication, and sensors inside for recording temperature, salinity, and currents.

Sailing Robots

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.

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.

The Pegasus missions utilise the Gumstix as the main flight computer which gathers GPS data, triggers the onboard camera and also transmits data. The most recent launch of Pegasus VI included a data downlink and also SSTV transmission of 'real time' images.

Features of gumstixs used:

• GPS (serial, compact flash and onboard)
• Interfacing with mobile phones/gm862 module (gnokii)
• Interfacing with radio (Aerocomm 868mhz radio modems + 434mhz beacons)
• Using GPIOs to trigger camera shutters + cutdown circuits
• Batteries

Acroname Robotics

Acroname set up their Garcia robots using a Gumstix verdex configuration.

Chatterbox robots

The Autonomy Lab at Simon Fraser University, Burnaby, British Columbia, Canada is designing a fleet of small robots around Gumstix boards. 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.

Flockbot robots

FlockBots Open Robotics Specification Wiki at George Mason University: Washington, DC, USA

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.

Mapping & video via radio controlles helicopter

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?)

Rotary wing UAV

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.

Flightstix

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)
• GPS

The hardware used to develop FlightStix consists almost entirely of donations from various electronics manufacturers, including GumStix, Inc.

Binocular vision Gumstix

I used a gumstix to give my FIRST robot binocular vision, and over the summer I'll be using a robostix and the CMUcams to write an easy-to-customize binocular vision implementation with the CMUcams for gumstix robotics projects.

RoombaNet at MIT

The newly-released Roomba Serial Command Interface (SCI) allows the user to drive a Roomba around and read out sensor data. My application has been to control the Roomba using a neural network, but the system is basically a tiny Linux box, so the possibilities are only limited by what will fit in the flash space. This will let you hack your Roomba with complete freedom.

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.

AMFO-1/Bobby

Montevideo, Uruguay.

• AMFO-1/Bobby (Spanish)

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.
