Qwerk Robotic Computer from Charmed Labs

Friday, December 8th, 2006

This is a great looking piece of hardware. Check out all the specs below. This is a very exciting time in robotics to have so many computers of this type coming out. ARM chips are becoming fairly powerful and there are ways to run high level object oriented programming language apps on them. The world of PCs and embedded systems are continuing to merge in many ways. The Qwerk looks like a great development platform for roboticists.

From the Charmed Labs site: “Qwerk is a powerful embedded computer with lots of I/O capabilities specifically for robotics.  Qwerk is being offered as the “official” Telepresence Robot Kit (TeRK) hardware, as well as for general applications in robotics and mechatronics.”
