A farmer uses an automated robot to plant seeds in the field. State what is meant by the robot being automated. Give three characteristics of a robot. The robot plants seeds and stops when it reaches a fence. It then turns and continues planting seeds. The robot uses sensors and a microprocessor to know when it reaches a fence. Explain how the robot uses sensors and a microprocessor to know it has reached a fence. Give two advantages of the farmer using an automated robot to plant seeds. Give two disadvantages of the farmer using an automated robot to plant seeds. The robot is adapted to have machine learning capabilities. Explain how this will improve the robot.
