Re the weeding robot -- you may be thinking of https://tertill.com https://tertill.com iRobot founders' new thing. Small, and undercapitalized, but promising.

Neat, and promising, though not the one I was thinking of. I think it might have been this one, Acorn by Twisted Fields: https://community.twistedfields.com/t/introducing-acorn-a-precision-farming-rover-from-twisted-fields/17 https://community.twistedfields.com/t/introducing-acorn-a-pr... https://www.youtube.com/watch?v=NsyEIgKVM5E https://www.youtube.com/watch?v=NsyEIgKVM5E

  Hey that’s my robot, thank you for sharing it! I just published a new article to go with our latest video. This one takes a closer look at the vehicle subsystems. https://community.twistedfields.com/t/a-closer-look-at-acorn-our-open-source-precision-farming-rover/108 https://community.twistedfields.com/t/a-closer-look-at-acorn...

Tertill is cool and all, but for a new garden, you still have to weed until the payplants are big enough to trigger "collisions". There's no magic in sensing: It just kills new growth.

  It also looks like you need to give it room to move around? Look at all that space that could be used for more veggies!

    I'm guessing some veggies need to be planted that far apart so there's enough nutrients in the ground for all of them to grow fully
- nobody_nowhere 5y ago
  Yeah, seems to assume you're going to put protectors around the 'good' plants or something at first. Still, I could see some interesting swarm behavior opportunities for the right types of plants and growth stages...

  You can just surround the new plants with the plant guards that come with the robot.
