Technology

As you point out, versatility is a huge feature. You can build one type of robot and use it for all kinds of different applications. This also means you can reuse the same robots for different jobs as needed instead of having to get a robot for every specific task. Another advantage is that you only need one set of parts to repair all your robots. Unitree can already make humanoid robots at around 10k a pop, and I imagine price will only keep going down.
