About pib (printable intelligent bot)

pib (printable intelligent bot) is a free, open-source 3D-printable humanoid robot developed by isento GmbH in Germany as a hands-on platform for learning AI and robotics. The physical robot is a life-size humanoid upper body: a head with moving neck, two articulated arms with tendon-actuated hands and fingers, and a torso meant to be mounted on a workbench, clamp or rig. The pib-stls repository holds the complete printable parts library (grouped into Head, Body, Arm and Hand & Finger; the pib#5 set replaced pib#4 in September 2026) released under GPL-3.0 (the pib FAQ states AGPL-3.0). The robot is driven by Tinkerforge servo bricklets controlled from a Raspberry Pi, with a ROS2-based control stack (pib-backend, AGPL-3.0) providing motor control, camera, voice assistant and a Blockly visual programming interface. Build guides, the bill of materials and assembly tutorials are published on pib.rocks.

How to build pib (printable intelligent bot)

5 steps

Steps marked Motari summary condense the linked source; follow the source for exact instructions.

Print the parts library
Print the pib#5 parts from pib-rocks/pib-stls (Head, Body, Arm, Hand and Finger) using the pib#5 printing checklist for quantities. pib recommends PETG, with the hand inserts in a flexible filament; the full set needs about 10.7 kg of filament.
Motari summarypib.rocks/build
Assemble arms and hands
Build the arms and tendon-actuated hands, mounting the servos for each joint per the pib.rocks assembly tutorials.
Motari summarypib.rocks/build
Build head and body
Assemble the head and neck, then the upper body, following the pib#5 building instructions. pib is an upper-body robot meant to be mounted on a workbench, table clamp or rig.
Motari summarypib.rocks/build
Wire Tinkerforge + Pi
Connect the servos to the Tinkerforge servo bricklets and the Raspberry Pi controller per the pib.rocks wiring docs.
Motari summarypib.rocks/build
Install pib-backend
Set up the ROS2 pib-backend stack on the Raspberry Pi for motor control, camera, voice and Blockly programming.
