The current electronics are a big area for improvement for us. Anyone familiar with 3D printing will note that we’re using essentially the same electronics stack: stock Pi, Arduino Mega, RAMPS, Pololu stepper drivers. None of these electronics are meant for extreme conditions such as those found in automobiles, though when we eventually develop our own FarmBot-specific electronics we will be looking at putting in more robust components.
The power supply and vacuum pump are stored in a rain-proof box, but they are not IP rated. In Genesis v1.3 we are planning on moving the vacuum pump to a location on the z-axis and putting it under a plastic housing, removing the rain-proof box entirely, and sourcing an IP67 power supply.
Something else we would like to do (though it might be in future versions beyond v1.3) is have an electronics enclosure that is fully sealed, where everything inside is wired up to through-panel connectors. Then the external motors/peripherals/power would plug into the box with sealed connectors.
We’re also planning to develop a PCB for the UTM that allows it to be plugged in, with one sealed connector, and it will have gold-plated pogo pins as the electronic contacts for the tools.
