A 3D cultivator is capable of manipulating the soil in a bed of seedlings in not only the X axis (forwards and backwards) but also the Y axis (side to side). and Z axis Conventional cultivators only operate along the x axis.
The next stage is to fit cameras to track the crops and install a hydraulic mechanism to momentarily stop the cultivator in the X axis to enable Y axis movement of the set of claws. The tractor itself will trundle along unperturbed.

Start of assembly:
Circuit diagram (aluminium manifold not shown):
The machine now has hydraulic rams on the wheels for side to side leveling, rams on the vertical and horizontal frames and a tow hitch which is vertically adjustable. Next couple of tasks is to assembly the claw mechanisms and install double acting solenoid, single acting solenoid and proportional flow divider valves and associated pipe work.
This animation shows a previous version of the WEEDINATOR built in 2018. The project was successful, but the machine was very slow and could not do anything else. This 2D cultivator is separte from the main robot and is about 20x faster as it uses the robot's wheels to move forwards in the x direction and has multiple claws operating simultaneously.
Shown in it's working position ready for the in-row wheels to be attached. Each wheel needs an independent leveling adjustment.
