A project log for WEEDINATOR 2019

The WEEDINATOR project continues .... The inevitability of robots working on farms draws ever nearer ....

The weeding claw has previously been tested on this tractor mounted machine as shown above. Now it needs to be replicated on the WEEDINATOR, but instead of four claws working simultaneously, we'll just have one.
Drawings are sent off for laser cutting. Should have components back for assembly in 2 weeks time. Check out 'Claw Mechanism' zip in the files section for dwg drawings.

The claw is powered by an ACM604V60-01 motor and is welded to a 20 mm shaft. The central plate above is bolted onto the Z axis plate (left) and has pillow bearings for the claw and an attachment plate (above) welded on for the motor. The whole claw mechanism can be quickly removed and replaced with other devices to be designed and built in the future.

Hooray, this is what I wanted to know! Just wondering if you could improve the accuracy of the head to the point where you can try alternative weeding treatments. I'm thinking saline solution injection like for starfish eradication or laser burning the weed crown. Plenty of other esoteric options out there, I'm sure!

I use a weed prevention technique so weeds never appear in the first place. Accuracy will given by recognising the plants as a 2D grid with cameras.
