Farmbot DIY in china

[maikangquan]

We build a farmbot and it runs very well.But our UTM is made of 3D printing so it is not durable。I don‘t like plastic parts，So we plan to use CNC to make it by aluminum 6061，But it’s a little expensive（one utm cost is up to 200cny）， I’m trying to modify the structure to reduce costs，it just cost 60cny now。
and the smt for pcb is too diffcult for me，so I redraw the pcb so we can plug Raspberry pie and atmega 2560 in it。It can be used as the original PCB and is much simpler.Later, we will change all plastic parts into metal，At the same time, the way of rail car dragging is considered to realize large-scale planting。
