Futurama Bender Cosmetics

This article is about building Bender the real robot on top of the Robot X walking robot.

There are some YouTube videos about this section, or scroll down for pictures and words.

I built a 3D printed frame which attaches to the Robot X chassis, this is printed in ABS and solvent welded together with Acetone:

The head of Bender is printed on the Lulzbot MOARstruder with its 1.2mm nozzle. It’s printed in PLA in multiple sections:

Bender’s head is animatronic – I’ve built eyes which each have a servo to rotate them and also move them up and down. This gives Bender quite a range of facial expression.

Bender’s mouth is  made from a motorised barrel that turns inside the hole in the outside – the teeth are drawn on clear acetate which stay stationary. Check out the video above to see the action!

I’ve skinned the body up with 6mm foam LD45 foam, which has been painted and sealed with PVA, plastidip, and automotive primer. The door has a separate frame part behind it.

The arms are made from a 3D printed nylon section which is slightly flexible, and ABS discs which are pulled by servos and string to make two joints in Bender’s arms.
