Worx Landroid wheel cleaner

thingiverse

This my first contribution on Thingiverse. All comments are welcome. By these rainy days, the wheels of your robot are sometimes full of mud at the end of a mowing session. This little tool will help you to clean wheels and other parts of the brother of Wall-E. Prefer PETG with high infill and print on the side to have a more robust tool. Additional information: If like me you have zones without 220v Main Power supply available. You can easily reproduce the signal in the peripheric wire necessary for the robot to work. The signal is square wave at 76HZ (-0,+0,2hz), duty cycle 1% high (1% strictly) and 99% low, signal has to be 15 to 20v amplitude. It is easy to reproduce with an Arduino Uno (an ATtiny can also do the job also), a IRF540N Mosfet to amplify signal, a 22ohms/ 3 watts resistor to reduce current in the perimetric wire and a 4S RC Lipo battery (plus other resistors). Everything soldered on a shield for Airduino and you are ready ! Put your robot in the zone (manually), push 3 times START on robot panel when it's in stand-by mode, enter the cutting time, valid with OK button and watch your robot working for the time you define. I hope this will help ;-) NEW: ino file for Arduino Uno or clones (please translate comments before download in the board) and the schematic are available here. I hope this will help. Let me know if you realize a batch of real clean PCB for arduino, thk... ;-) My work is free of charge so, you can propose or make kits for your family and friends but no commercial benefit is allowed. I don't want to see this kit or an assembled product on ebay for 100$ or more. Thank you for your understanding.
