POLICY. learning of the system dynamics in changing working conditions," Chowdhary said. Chowdhary expects these applications to evolve as AI becomes more adaptive over time, so that the system performs reliably in a variety of field conditions. He also expects that "the AI will learn over time to perform better when it encounters situations it has seen before." Currently, the robot is about a half-meter long, three-quarters of a meter wide, and 30 to 40 kilograms in weight. "We hope to re- duce both the width and the weight quite a bit," Chowdhary said. "The reason we want to make it less wide is to have it fit more easily between crop rows. We also plan on reducing the weight as part of bringing down the costs of manufacturing the robot." In the future, the researchers may design multi-agent systems "where drones and robots and harvesters, all kinds of equipment, work together," Chowdhary said. The research team aims to have the robot on the market by 2021. The goal is for the robot to cost $5,000 to $10,000. The researchers are working on the next iter- ation of this robot, which will be designed from the ground up with cost reduction in mind. The new robot will utilize technologies such as 3-D printing and less expensive off-the-shelf sensors to reduce the cost. In addition, when the robot is manufactured on a large scale, cost can likely be reduced significantly. "A n ag r icultura l robot that cost s just $5,000 is unheard of—agricultural equip- ment nowadays usually costs hundreds of thousands of dollars," Chowdhary said. "We want to provide tools to breeders that they can actually use." VISIT US AT BOOTH 2126 AT XPONENTIAL 2017 IN DALLAS!
