So I have been pondering theft PREVENTION measures. I have a spare car alarm I could use and maybe with some sensors could use it to sound car alarm if the robot is tampered with. So I have a couple ideas but I want to open a discussion about this as it is something that any autonomous robot indoor or outdoor faces.

viper / Directed 2 way alarm system ( reports back to a remote when a sensor is set off.

Tilt Sensors, physically arranged in 4 directions and mounted to the frame. Forward, backward and side to side.

Plunger sensors or magnetic

4, two on the from lid and two on the rear.

Magnetic sensor, one inside the lid of the sensor stalk.

Ok so 9 sensors there.

Lastly Maybe I could have something that senses the wheels are turning but not energized , or maybe the brake release could have a magnet sensor.

Basically I want something that is very undesirable to drag through my yard to steal.
