I created a prototype head scratcher using a Stewart-Gough Platform offering 6 degrees of freedom.
This was done using six AX-12A motors daisy-chained together. A full write-up of the process can be seen here: David McDaid Electronics - Stewart Platform Head Scratcher
Oh, I need that…! I see that there are various modes, but can you control the torque as well? If you can adjust intensity, direction, etc via mobile app, it can be a product that sells well in nursing homes, beauty salons and nail care salons.
