Bi-Weekly Build Session Announcement

All bi-Weekly build sessions will be cancelled starting 11/29/12 until early 2013. This time of year most members’ schedules become very busy with family trips and holiday activities causing bi-weekly build session attendance to drop. In response to this we decided to cancel our build sessions over a few month period in 2011 and we’ll be doing the same this year.

We will discuss when to resume build sessions during our club meetings in early 2013. Happy Holidays to everyone!

ASME Osmoces – 10/13/12

CIRC was invited to participate in the 2012 ASME Osmoces event which stands for (Open Source Mechatronics Outreach & Creative Exchange Symposium). This event took place at the IIT Rice Campus in Wheaton, IL and was hosted by the Fox Valley ASME (American Society of Mechanical Engineers) chapter. Club president Dan Toborowski attended the event and brought his Marble Maze, FPV quadcopter, and our RoboMagellan robot Wheel-E. This event was intended to bring together members of the hacker community, individual hobbyists, professional engineers, and educators to share knowledge and ideas about open source technology, robotics, microcontrollers, and more. Several presentations and classes took place through the day focused on topics ranging from 3D printers, Raspberry Pi’s and Arduinos to how to use Kickstarter. By far the most popular presentation however was by the keynote speaker; JPL engineer Steve Collins. Steve is the Cruise Attitude Control System Engineer for the Mars Curiosity Mission. Steve is shown below next to Wheel-E!

CIRC was excited to be included in this event and really enjoyed the opportunity to network with so many interesting people from the local hacker space, robotics, and education community. We look forward to next year’s event!

2012 RoboMagellan Update

Wheel-E V2.1 competed at the 2012 Chibots SRS RoboMagellan Competition on August 4th and won 2nd place! Several updates were made since the 2011 year including replacing the Mini ITX computer with a Dell Netbook, replacing the GPS and Compass with an ArduPilot board, and upgrading from Nimh batteries to 4S LiPoly packs. A huge thanks again to SolidWorks and MaxBotix Ultrasonic Rangefinders for their continued support of this project! While Wheel-E was able to successfully complete the course once, our other 2 runs did not go as well due to compass accuracy problems and the lack of functional object detection. We’ll return next year with these problems hopefully remedied.
