The proto-prototype of the servo-box is better than i thought. As always, with some cnc-made aluminium parts, the box could shrink in its size to around 40 cm in height and 30 cm in width. Then build into a nice electrical cabinet. On the picture you can see, that it has 5 steps, on every step there will be 8 servos for one finger. Then you can use it on e.g. warehouse vehicles and grab stuff.
