I'm in the process of creating my own TurtleBot since I have most of the parts already. However it seems the sparkfun gyro suggested on turtlebot.com has been discontinued. Can anyone suggest a good alternate gyro or IMU? Preferably the device would be a drop in replacement for the gyro (i.e. will work with the TurtleBot dashboard w/o modification).
This post (gyro-for-turtlebot) seems to answer your problem
I assume you are aware you could buy the gyro built in with this power board http://store.iheartengineering.com/TurtleBot-Kit-Power-Sensor-Board/dp/B005CDNI9U?ie=UTF8&id=TurtleBot%20Kit%20Power%20Sensor%20Board&field_product_site_launch_date_utc=-1y&field_availability=-1&field_browse=3001597011&searchSize=12&searchNodeID=3001597011&searchPage=1&refinementHistory=brandtextbin%2Csubjectbin%2Cprice%2Csize_name&searchRank=salesrank from I heart engineering.
I'd suggest Xens - see this question or Microstrain - see this question.
AFAIK, for the Turtlebot one just needs angular rate (gyro) information about the z-axis. It appears to me that full 6/9 DOF XSens and Microstrain IMUs are overkill for this application, especially considering their cost.
If you're looking for something which can integrate directly into your PC but doesn't have the cost of Xsens or Microstrain, these IMUs have worked well for us in the past.
