A better question is what has he done since he unveiled his creation in 2016? His crowd funding for a book and 3d files on assembling your own robot is still half way off selling enough preorders to be able to do a print run(will it print in 2019? 2020?), he knows better than to sell an easily pirated ebook in this day and age. His 'share lab' that was supposed to be a community of fellow robot builders that collaboratively improved his robot design is nothing but a vague promise he made years ago. Even if he released his book tomorrow for free and set up a basic wiki and web forum for his project it's too little too late.
Either this guy squandered all the mainstream media attention he received or he doesn't want the hassle involved with helping others and would rather work on his own. I'd put my money on the later as the majority of people on the internet nowadays are terrible.
