Like many of you, I’d imagine, I have at least three old Palm Pilots scattered about my place, collecting dust in drawers and boxes. I just never got into the habit of using one regularly. But all still work, so I’ve started hunting for alternate uses for them. Look for something in the May issue on this, but as a preview, here’s one of my favorites: A kit from Carnegie Mellon’s Robotics Institute for a fully autonomous robot that uses the Palm as a brain. It even has optical sensors to get around walls. Seems like a great way to get started on robotics projects. —Mike Haney
