A simple and cheap robot lawnmower for small gardens with things to bump into everywhere.

Simple principle, the rear wheel turns different depending on direction due to offset rear axle.
The cover is connected to a switch that flips over and change the drive motor direction when it hits something.
No guide cable needed.

Just charge it, put it on the lawn and let it run until the battery is out and its time to take it in for a charge.

For more info see the assembly manual.
It shows a complete assembly, instructions on the electronics and much more.

Enjoy!
