GuidelinesGuidelines Device should be controlled by BS2. Incorporate and document hardware and software

features to prevent damage to the BS2 IC and other components on the device.

Project must include some form of a user interface so that a human user can monitor the device.

Project must utilize at least one actuator. Project must utilize at least one analog and one

digital sensor. Actuators must be controlled using sensory

feedback.

ObjectiveObjective

To implement a autonomous machine that makes the decision of irrigation control based on climate.

Initial PlanInitial Plan

To make the robot go on a predefined pathway.

Stop at predefined intervals.Sense the humidity and temperatureFollow a line and dock.Actuate the valves and water pump based

on humidity levels.
