GUARDIAN

The Guardian is a small guard robot that lets you see what's happening at home. The robot is controlled using text messages. The robot software is programmed to many different features. The Guardian has six different operating modes, which are Guardian mode, Free mode, Resting mode, Remote mode, Move mode and Testing mode.

When the robot detects an intruder (Guardian mode), it sends a warning SMS. You can also freely control the robot SMS messages in Remote mode.

The camera can be turned on remotely at any time. Then you see the home of live pictures via smartphone.

The Guardian has two powerful batteries, which last about 15 hours. The robot monitors the battery status.

This web-site you will find a robot building instructions, wiring diagrams, etc. You can take all of them free to use. See the code of the robot and learn more about its. The code is well commented.
