This is a cool idea, although I’m skeptical of it being cost effective. And considering you’ll have to clean off every one of those expensive robots after each spill, it’s a messy proposition as well. Still, it’s a great idea and could provide a nice boost to spill containment efforts. It’s still a concept at this point, but feel free to DIY one in your garage (but maybe add longer arms).
