Head and hands for a Makeblock robot (see version #1 for other parts), powered by G9 micro-servos.

The left hand has only one servo, which powers the claw from https://www.thingiverse.com/thing:2714159 (thanks and credits for that go to jeffballweg).
Note that you will have to mirror the part in Cura to obtain the left-handed version from the STL.

The right hand is powered by two servos, one for the claw (a remix of the above claw) and one for the wrist. The wrist_connector piece goes on the servo, and is joined with the wrist axle via a flexible tube. You can mirror this part in Cura to obtain an identical left hand.

The servos are connected to Makeblock RJ25 adapters. In my case I had to use PORT_3 and PORT_4 of the Makeblock board to be able to power two servos from a same RJ25 adapter.

Also included is the 'shoulders' piece with a mount for the Makeblock gyro sensor and a microservo for the head (not pictured).

In addition, I include several wheel mounts which I've used for my specific tracks geometry.

Update (Oct 24, 2020): added a head for this robot, and a new photo.
