The next of the sheets goes a lot further into mechanical design, showing several different configurations for hands, with notes and ideal measurements for each. They all look distinctly like bird talons to you, but you suppose that makes sense. From what you could tell, the closest analogue to your hands were minotaurs, which were somewhat rare. Some form of avian species was the next best candidate, and besides them, griffons were more readily available and used their talons to manipulate objects. The designs allowed for excellent flexibility, but you were worried about how many motors would be necessary.
