The apple picker is a prototype, from Abundant Robotics, an SRI spinoff. It suffers from being a Silicon Valley R&D effort - the computer technology is cool, and the mechanical parts are too flimsy. Somebody needs to get those guys some hardass mechanical designers from John Deere or Caterpillar or Ponsse who know how to make machinery work reliably in the field. I think they're still at the angel investor stage. They'll need another funding round soon, and if they're lucky, their funder will know who to put in there to get the thing out of R&D and into production.
