In early April, Pegasus Team GPLed their DARPA Grand Challenge telemetry data. Now they've gone a step further and released a version of their Python drive-by-wire software under the GNU GPL. It's very interesting to see code being used on one of the DARPA entries. This code is a simplified, early version used during testing to control the Pegasus robot remotely from a Laptop by using keyboard commands to accelerate, brake, and turn. Keep in mind the released code is intended as an example only. So, before you try running it as-is on your 1 ton, 300 HP DARPA robot, read their dislaimer: "if you do not know what you are doing do not use this program on a motorized vehicle or any machinery for that matter. Even if you know what you are doing, we absolutely cannot be held responsible for your use of this program under ANY circumstances."
