To our tinfoil hat wearing friends, please note: This was not a classified event and required no clearance to attend. No one is coming to take me away … so far.Two weeks ago we had the privilege of attending the proposal day for the new DARPA challenge.What’s DARPA? If you like things such as the internet then thank DARPA. As a matter of fact the internet started its life by being called ARPAnet because it was developed in conjunction with DARPA and educational researchers.In this particular challenge they are looking for an autonomous solution to traverse, map and possibly provide aid in a subterranean environment.Previous DARPA challenges have focused on technologies such as autonomous cars so being able to attend the challenge proposal day in Washington DC was quite a privilege.
