elrobot
elrobot provides printable designs and assembly materials for a robotic arm used in physical-AI and imitation-learning experiments.
It is a hardware subproject inside norma-core. Building the arm involves printed parts, servos and assembly; the wider repository also contains software for robot data collection and control. Use this as a first read, not a recommendation. Open the original project before trusting details like terms, limits, privacy, cost, setup, or safety.
What it is
A robotic arm to build
Design files and assembly manuals describe the physical hardware.
Why it stands out
Leader and follower versions
Separate builds cover the arm moved by a person and the arm that follows it.
Availability
Files in the norma-core repository
The hardware folder contains print files, design files and a manual for each version.
Why it matters
What makes it useful
For an imitation-learning experiment, someone has to demonstrate a movement. The leader arm gives that demonstration a physical input, while the follower is the arm intended to reproduce it.
What to know
Where it fits
The hardware folder is the fabrication starting point. Norma-core also has a Station application for data collection and control; assembling an arm and setting up that software are separate parts of the work.
Notable points
What stands out
The project supplies preconfigured 3MF files as well as STL files. You can start with the supplied print setup or slice the STL parts yourself.
Before using
What to review
Choose the leader or follower manual before ordering parts: their motor and power specifications differ.
Match the printed parts and electronics to that version's assembly instructions.
Reader fit
Who may find it relevant
Builders with access to 3D printing and experience assembling servo hardware.
People setting up a physical demonstration-and-following experiment who need design files rather than a finished arm.
Editorial note
Why LifeHubber lists it
Similar-looking arms do not mean identical parts. The leader design uses lower gearing to make it easier to move by hand; the follower uses a different servo specification. That difference matters when preparing the two parts lists.

Reader note
Before relying on this entry
LifeHubber lists entries to help readers inspect AI projects, not to endorse them or prove they are safe, suitable, accurate, maintained, or right for a specific use. We do not verify every entry in depth. Before relying on anything listed, review the original materials, terms, privacy practices, limits, and risks that matter for your situation.
What to explore next
From the arm to the learning workflow.
The arm designs cover the build. LeRobot provides another view of the datasets, training and robot interfaces involved in imitation learning.
