Perrone Robotics, Inc. (PRI), based in Crozet, Virginia, was formed in 2003 and has been developing mobile autonomous robotics solutions ever since. Early development work focused on making it easier to configure and program robots. Then, in 2005, we took on the DARPA Grand Challenge and 2 years later the DARPA Urban Challenge. Our MAX full-stack robotics software platform was put to the test demonstrating a rapid and robust means for building fully autonomous ground vehicles during both challenges. These challenges were established by the Defense Advanced Research Projects Agency (DARPA) to accelerate the development of fully-autonomous ground vehicle technology. PRI’s entries competed very well against much larger and better-funded efforts which helped us understand the strengths and work to be done on the MAX platform.
