comes this shield from Creative Robotics. Full details are at this URL but this is what it looks like. It allows you to connect two Hub-ee wheels to an Aduino and even access the feedback from the readers. In addition, it also has servo connections so that a pan and tilt camera or maybe an ultrasonic scanner could be run from the same board. As far as I can tell, this board isn't yet available from the distributors.
On a completely separate thought, we have finally discovered what is causing my problems with the laser cutter software. The original files are being produced at the correct size but by the time they get to the cutter software, they are so heavily reduced in size that the software can't see some of the lines and holes. We are still working on a fix.
