Tutorials, deep dives, news, and architectural opinion. Free, no paywall, forever.
Six weeks ago this site had one tutorial. Today it has every topic in robotics — from forward kinematics to humanoid whole-body control to BOM cost engineering. Here's what shipped and how to use it.
A beginner-friendly walkthrough of the ESP32-S3 microcontroller — what it is, why it's the best chip for your first robot in 2026, how to install the toolchain, and how to blink your first LED. Part of the 'Build Your First Robot' course.
A community for DIY robotics and physical AI. Here's what we're building and why.
Figure, Tesla, 1X — the humanoid race is closed-source. Here's why the open movement is still the one that wins.
Browser-based robot physics with Rapier 3D, a Monaco editor, and a JavaScript control loop. Here's what's coming.
No robot required. Install, launch turtlesim, publish a velocity message. The fastest honest intro to ROS 2.
$20K for a NEO, $30K for a Unitree, $16K for a G1. Or print Poppy for $500. A year of living with both.
A 6-DOF arm built from MG996R servos, a PCA9685, and an ESP32. Pick up a coin. Sort blocks. Under-promise, over-deliver.
Sim-to-real is finally good enough for amateurs. Here's the minimal stack: MuJoCo MJX, domain randomization, PPO, and a real quadruped on a soft mat.
SpotMicro, Mini Pupper, OpenDogV3, Bittle, and Bolt. A field guide with BOMs, skill ceilings, and which one to start with.
