That's brilliant. What about using a laser to destroy the weeds?

I suspect this would result in rather superficial weed destruction, since the roots underground would be unharmed and would cause the weed to regrow a few days later. Unrooting the weeds definitely sounds more reliable to me.

On the other hand, with a laser you could process huge areas at extreme speeds. Think 100 zaps a second.

The robot in the article just pushed the weed underground a few inches. I imagine that some weeds would just pop back after a week, and that the robot would just punch them down again.
