  • Arduino example and support library now available for the Unicoder ME-210.  We've also updated the Arduino example and support library for the WheelCommander WC-132.
  • The Nubotics Web Store is now open!  Save up to 50% on select products!
  • After 9 years as our main distributor, Acroname has decided to change the focus of their business.  Thanks Steve, Suzanne, Tim, and the rest of the Acroname team for all your support.
  • NOTICE: we still sell through these great distributors: Active Robots, Hobby Engineering, and Solarbotics.
  • We've released an updated Unicoder ME-210 manual; improvements include clarification of the location of pin 1, byte ordering of multibyte values, and how changing constants takes place immediately.
  • We just posted a new version of the Arduino support library and example code for the WheelCommander.  This new version supports I2C as well as serial, and on a Mega Arduino, supports use of the additional serial ports.
  • We are proud to announce our new  user forums!  We'll maintain the old email lists for a while, but please submit all new  support requests to the new forums.
  • We've posted updated manuals for the WW-11 (rev 1.03), WW-12 (rev 1.02) , and WC-132 (rev 1.14).  The WW-11 and WW-12 manuals now include a number of new diagrams and expanded FAQ sections.  The WC-132 manual now incorporates the FAQ (with additions) previously only available on the website.
  • We've created a new WheelCommander software support page, with access to our new Arduino library, Player/Stage driver, and RoboRealm driver. Enjoy!
  • We have added a small photo gallery showing WW-02s mounted on various Solarbotics gearhead motors, and another showing WW-01s mounted on, of all things, automobile wiper motors.
