It's an easy to build robot hand that you can move with a Raspberry Pi controller using a mobile phone.
Play record and share movement recordings. It's easy like Spotify for robots.
Movements for this robot can be found under "lefthand" tag in http://gigabrain.io/movements/list
The parts are from InMoov forearm and FlexHand. Glue together the hand part to the lower forearm. Wrist extension part is also possible to attach but it's not in this collection.
Wire the fingers with a nylon string, nylon powerful fishing line is a good basic option. You can use standard servos MG996R metal gear servo is quite noisy but used in this example. You can look for InMoov recommendations.
We'd like to hear your feedback on improvements and other as well.
Print the "FFX - Finger Hinge Plate" using a flexible filament. This part was printed using 3 different filaments in the hand part.
Apply hotglue in the servobed to screw the servos. There is a 4mm gap between the servobed and servo mount if you use standard servos.
