Direct Herbicide Application With an Autonomous Robot for Weed Control

摘要

An agricultural robot for weed control was developed and tested. The robot consisted of adigital video camera, two robotic arms, four wheels, a computer and a radio controller. The chemicalexperiments were done in both the fields and the greenhouses. The results showed that only a smallamount of regular spraying dosage was needed if chemicals were applied onto cut weeds directly.Velvetleaf, water hemp, foxtail and crabgrass were tested in the chemical experiments. Sincechemicals were mopped onto the weed's surface, there was no chemical droplet drift at all. There arealso a lot of benefits for the environment from these techniques.<br><br>The long-term objectives of this project are to develop an agricultural robot for weed control withautomatic navigation capability and higher efficiency.
