Aside from these not currently existing, they also have far worse failure modes than robots with lasers. Introducing species for biological control methods have a long and storied history of becoming a problem as bad as or worse than the original problem.
> It’s not just chemicals. Weeds can become resistant to any type of control method. In a classic example from China, a weed called barnyard grass evolved over centuries to resemble rice and thus evade hand weeding.
Laser wielding AI robots already exist, and are being used commercially.
It has a guidance system that is connected to a wheel that is friction attached to the steering wheel and turns it on an old tractor. A newer system with an old tractor - https://youtu.be/t0uIYjOds_o
Newer tractors have this built in. The modern tractor cab is a mini data center. https://youtu.be/ZhOvchjeqgM (and you can see that he's not touching the wheel most of the time)
