I started thinking about this a bit more & did a really crappy model (My first)
- Red bits are 20x20 extrusion
- Black bits are ‘carriages’ that slide over the extrusion
- Blue bit is just a hinge
- Orange bits are linear actuators
- Grey bits are aluminium plates, to which you attach a sharp blade on the leading edge.
You drop it over your lettuce, close the actuator, the lettuce is cut and falls onto the plate. You move the assembly over your harvesting crate and use the other actuator to tip it in.
