It's an interesting concept. If you scroll through the page you'll see it's actually pretty strong. The blanket pick up video should actually be the first video.

My fear is that a company that has the money to build and manufacture this will rip off the idea and use their resources to polish the concept. With a lot polish, this type of thing can be useful in certain environments.

Cable robots have existed for decades this is not a new concept. Anyone who wanted to rip it off could have done it long time ago.

So, you fear someone else making it "useful in certain environments?"
