Projects
Origin stories and ongoing histories of individual open-source robotics projects — how they started, what they changed, and where they're headed. A narrower, faster-moving companion to History's decades-spanning industry sweep.
OpenArm
A fully open-source, 7-DOF bimanual humanoid arm from Enactic, a Tokyo robotics company spun out of Reazon Holdings — priced from $6,500, licensed under Apache 2.0 and CERN-OHL-S-2.0, and built around a 'make SOTA reproducible' standardized evaluation platform now integrated into Hugging Face's LeRobot.
LeKiwi
A $184–$499, 3D-printed, three-wheel omnidirectional base from a University of Illinois student robotics group that turns Hugging Face's stationary SO-100/SO-101 arm into a mobile manipulator — now a supported robot type in the official LeRobot library.
The History of LeRobot
From an ex-Tesla engineer's PyTorch library to a $100 robot arm, a 25,000-star open-source project, and 0.6.0's world models — how Hugging Face's LeRobot became a reference stack for AI-driven robot learning.
Open Duck Mini
A sub-$400, 3D-printable bipedal robot that learns to walk via reinforcement learning, built by a Pollen Robotics engineer as a Disney BDX-droid-inspired side project — and later chosen to demo on-device AI at Google I/O.
Amazing Hand
An 8-DOF, fully 3D-printed robot hand from Pollen Robotics with every actuator self-contained inside it, costing under €200 — a simplified, open-source take on academic dexterous-hand research.
SO-101
A 6-DOF, fully 3D-printed leader-follower robot arm pair from Hugging Face and TheRobotStudio, priced $100–$500 and built to teleoperate and train robot-learning policies — now the reference hardware for the LeRobot library.
