Japanese company Fuji Heavy Industries has developed a robot that can perform farming tasks autonomously. The robot runs on gas. It is about 6.5 feet (apprx. 2 meters) long and 1 meter high. The navigation is done by laser signals, which robot uses to determine its distance to reflective plates – which are placed in the farm at certain intervals. The robot will be available for sale next year for a price of $100,000. We will publish further details here as it becomes available.
