Three Robots

On a field in England, three robots have been given a mission: to find and zap weeds with electricity before planting seeds in the cleared soil. The robots - named Tom, Dylan and Harry - were developed by Small Robot Company to [blank] land of unwanted weeds with minimal use of chemicals and heavy machinery. Robot Tom can scan 20 hectares (49 acres) a day, collecting data which is then used by Dylan, a "crop-care" robot, to zap weeds. Then it's robot Harry's [blank] to plant seeds in the weed-free soil. Using the full system, once it is up and running, farmers could [blank] costs by 40% and chemical usage by up to 95%. "But you have to [blank] in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.
