micro 3D printer

Getting closer to ‘desktop factory’ all the time.

Printing ‘small’ parts at high resolution.

The world’s smallest 3D printer

From the picture, it looks like that connects to a computer through a standard [old style] serial cable [not USB]

The video says he built if for about 1500 € [in parts?], at todays conversion, that would be just over $2000 Canadian. He said it has the capabilities of a 60000 € commercial printer [$81100] !!

Jeremie and I had an opportunity to attending the announcement event for Beakerhead!

Aiming to be a fusion of science, engineering and creativity (a video presentation called to mind the kind of wacky robotic contraptions you see at Burning Man), Beakerhead is the brainchild of co-founders Jay Ingram, best known for his work with the Discovery Channel, and his partner Mary Anne Moser. Collaborating organizations at this point include the U of C’s Schulich School of Engineering, Mount Royal University,SAIT Poytechnic, Telus Spark, the Glenbow Museum and local arts groups such as the High Performance Rodeo, the Calgary Animated Objects Society and the Green Fools.

I’ve been following the online AI class from Stanford.  Included in that was a video with descriptive commentary of the robot that won the DARPA challenge.  The video is also on youtube.  The ‘trick’ was to overlay very accurate but short range laser sensor data, with much less accurate but long range camera vision, to ‘infer’ what was further ahead than it could see with the lasers.

Navigating beyond the reach of GPS

Found an article about some research to allow navigation / position detection where GPS does not work.  Bigger systems already use this technology, but the research is to develop it for use on small resource and battery life constrained devices, like cell phones.  That will also apply to small, mobile, indoor robotics projects.
