A New hand from Youbionics
There is a newer hand from Youbionics than the HandyLite, called Youbionic Hand 2021. It is driven by an arduino Nano as well. Using 6 SG90 servos, it adds an adaptive grip in the 4 fingers, and a contractible and rotatable thumb. Only 14 parts to print (though some of them 5 times), designed for printability, and properly oriented for the build plate.
With crowdsourced funds, we purchased the design. I will build one once the hardware parts arrive and post a critique of it here.
Here’s a youtube video of it in action:
