Getting a humanoid from a bench of loose parts into something that stands and walks is where most open projects fall apart, since documentation is usually the weakest link. The maker is tackling that head on with Asimov 1, an open-source humanoid built entirely from off-the-shelf parts so anyone can source the components and follow along.
The hardware is substantial: 160 parts spread across 7 modules, made from 7075 aluminum and MJF PA12 nylon, and driven by 25 actuators in 5 sizes. Compute comes from a Raspberry Pi 5 paired with a Radxa CM5, plus a 491Wh lithium-ion battery, a camera, microphones, a speaker and an IMU. The finished robot stands 1.2 meters tall.
The manual is the part that stands out to me. It is a step-by-step guide with 3D visuals that can be rotated and inspected at every assembly step, taking a builder from a bench of parts to a robot that stands and walks. Assembly runs through left leg, right leg, pelvis, arms, torso and head, with each module verified along the way. An Asimov Manager browser interface handles firmware setup and actuator ID configuration, with IDs numbered 01 through 25, and the robot's operational states are labeled DAMP, STAND and WALK.
Two things worth weighing. Self-sourcing every part comes to around $30k, which puts it well outside casual territory. And it is still unanswered whether the walking shown is the stock controller or a tuned one. The maker says the robot walks, talks and can be fully teleoperated, and that it is aimed at researchers and developers building on top of it.
