OS Delta robotic Arm project as possible Ally?

Few days ago, I came across a proprietary farming robot roughly similar to Acorn which used a Delta robotic arm to carry out its operations on the field.
As such I started to wander if perhaps there was some opensource project working on such a kind of arm, as it seemed to me that it might have been a brilliant starting point in the effort to make Acorn operational.

Today I came across this: https://www.deltaxrobot.com and Delta X - Opensource Delta Robot Kit | Hackaday.io

I hope you will find it useful!
