Anyone who has a hand impairment like a quadriplegic or has studied hand movement knows that full wrist articulation is paramount. The wrist can even expand and contract some atrophied hand and forearm muscles so that fingers partly open and close.
Even if this isn't their newest video, what it shows is sadly they don't understand fundamental hand/wrist finger interaction.
I suppose this is not a robotic related rant
