Re the weeding robot -- you may be thinking of 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:

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.

Edit: just submitted it as an article on HN if anyone wants to give it their vote: https://news.ycombinator.com/item?id=27634450

Very cool, thanks for sharing!

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.

[nobody_nowhere]

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...

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!

[Defenestresque]

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