2. Overview Objective Guidelines Initial Plan Resources Circuits Pbasic Code Video and Pictures Problems Improvements Real life cost and model Closing

3. Guidelines 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.

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

5. Initial Plan To make the robot go on a predefined pathway. Stop at predefined intervals. Sense the humidity and temperature Follow a line and dock. Actuate the valves and water pump based on humidity levels.
