Let’s be honest: The current generation of robotic lawn mowers sucks. Basically all of these bots drive in a random direction until they hit the border of the lawn, rotate for a randomized duration and repeat. I think we can do better!
Therefore, we have disassembled the cheapest off-the-shelf robotic mower we could find (YardForce Classic 500) and were surprised that the hardware itself is actually quite decent:
- Geared sensored brushless motors for the wheels
- A sensored brushless motor for the mower motor itself
- The whole construction seems robust, waterproof and all in all thought through
- All components are connected using standard connectors, therefore upgrading the hardware is easily possible.
The bottom line is: The bot itself is surprisingly high quality and doesn’t need to be changed at all. We just need some better software in there.
It’s so ironic that valetudo doesn’t support roomba considering roombas used to be a hackable robotics platform, even selling the robots without the vacuum components, with many models of vacuums shipping with serial ports right on top.
