Researchers say they're getting closer to developing robotic machines that can remove weeds from vegetable fields.

Scientists with the University of California say they've been testing several models that cultivate fields automatically. The machines use a technology that lets them remove weeds while leaving the crop untouched.

However, although they're showing promise, researchers say they still need to be perfected.
