- Deere & Co., well known for its green and yellow tractors, bulldozers and lawnmowers, has spent nearly two decades investing in technology and robotics.While a good deal of that R&D has been homegrown, the company also has been on a spree of acquisitions and partnerships with agtech startups, harvesting know-how as well as talent.While Deere made a big splash at CES and intrigued the investment community, Stephen Volkmann, equity research analyst at Jefferies, said, "We are very, very, very early in this process."Attached to the autonomous tractor are six pairs of stereo cameras that can "see" an obstacle in the field — whether it's a rock, a log or a person — and determine its size and relative distance.Images captured by the cameras are passed through a deep neural network that classifies each pixel in approximately 100 milliseconds and decides whether the tractor should keep moving or stop."
