This video was published in Oct. 2012, and somehow slipped past me unnoticed. At just over four minutes, it’s a brief but decent overview of the history of agricultural robotics and what’s currently available, as well as mentioning Prospero. (In case you’re not familiar with Cali Lewis, she has a (sometimes forced) upbeat style, but usually has her facts straight, as far as they go.)
