Drive a Rover on Mars
Richard McElligott writes "Hi, the Active Robotics Lab at University of Reading has put up an online networked robot that can roam around a simulated martian landscape. All you need is sun java from www.java.com and you can view streaming online video and control the rover around the landscape using only your browser."
You give the rover a destination, and a degree of rotation from it's current location, it then navigates the rocks and even goes around them if they are too big. The whole time it's sending back images to the workstation.
I got to run this thing for 5 hours at my local Space Day at a Smithsonian hanger in Dulles Airport. It was great for the first few times, but I got sick of explaining the thing to kids by the end. There are 3 on tour through the US now.
