Dexterous manipulation—the ability to grasp, adjust grip, and rotate objects within the hand—fundamentally distinguishes humanoid robots from industrial arms. This article presents a comprehensive specification for the Open Humanoid hand subsystem, covering the critical trade-offs between degrees of freedom and control complexity, underactuated versus fully-actuated finger architectures, tendon...

A 20-article engineering series building a fully spec-driven autonomous humanoid robot from first principles — locomotion, manipulation, vision, speech, power, and simulation.
Safety Systems and Fault Tolerance: Emergency Stop, Collision Detection, and Safe Failure Modes for Humanoid Robots
Humanoid robots operating in human-shared environments must implement multi-layered safety systems that prevent harm through hardware redundancy, real-time collision detection, and graceful fault isolation strategies. This article presents the safety architecture for the Open Humanoid platform (160–180 cm, ≤80 kg), covering hardware e-stop mechanisms with sub-100 ms response times, software wat...
Computer Vision: Depth Perception, Object Detection, and SLAM for Humanoid Robots
Autonomous humanoid robots operating in human-shared environments require a multi-layered computer vision stack capable of simultaneously perceiving scene geometry, detecting and classifying objects, and building persistent spatial maps — all within strict real-time latency budgets. This article presents the computer vision subsystem specification for the Open Humanoid platform, covering depth ...
Sensing and Perception: IMU, Depth Cameras, Force-Torque Sensors, and Sensor Fusion for Humanoid Robots
Reliable locomotion and manipulation in a bipedal humanoid robot depend fundamentally on the quality, latency, and fusion of sensory data. This article presents the sensing and perception subsystem specification for the Open Humanoid platform, covering inertial measurement units (IMUs), stereo depth cameras, six-axis force-torque sensors, tactile arrays, and joint encoders. We analyse sensor pl...
The Closed Robot Problem: Why Open-Source Humanoid Robotics Is the Most Important Engineering Project of the Decade
In September 1969, Neil Armstrong's flight suit was placed on public record at the Smithsonian. Every stitch, every zipper, every pressure seam — documented, catalogued, available to engineers, historians, and future designers who would need to build on what NASA had learned. This is how science is supposed to work. What you discover in public, you share in public. The knowledge compounds. Fift...
Bones and Skin: Structural Materials, Stress Analysis, and the Art of Building a Body That Survives
Picture this: an 80-kilogram humanoid robot loses its footing on a slightly damp factory floor. The fall takes roughly 0.4 seconds — the time it takes you to blink twice. By the time the software stack registers what is happening, the hip joint is already at 40 degrees of unexpected lateral deflection. Then comes the impact.
Actuation: Selecting Motors, Torque Budgets, and Degrees of Freedom for a Walking Robot
Actuation is the discipline where robotics collides with physics. Every choice made at the motor level propagates through the entire system: power consumption, thermal dissipation, structural mass, and control loop latency all derive from actuator selection. Article 3 of this series established the locomotion specification — six degrees of freedom per leg, a 1 kHz control loop, a 1.2 m/s normal...
Bipedal Locomotion: Engineering Gait, Balance, and Fall Recovery From First Principles
A human infant begins life unable to hold its own head upright. Within twelve months, it is walking. Within fifteen, it is running, turning, and recovering from stumbles without conscious thought. This developmental miracle is so universal that we rarely pause to appreciate what it requires: real-time estimation of a six-degree-of-freedom state, predictive control over roughly 600 skeletal musc...
Specifying the Impossible: A Complete Engineering Specification for an Autonomous Humanoid Robot
A humanoid robot is a system of perhaps 500 interdependent requirements. The locomotion subsystem demands actuators with specific torque curves, which constrain motor selection, which determines power draw, which sizes the battery, which adds mass to the structure, which increases the torque requirements for locomotion. Every specification decision cascades through the system. How do you specif...
The Open Humanoid: Why We Are Building a Robot From First Principles
In February 2026, Boston Dynamics announced that its electric Atlas humanoid had entered production and begun autonomous operation in commercial facilities. The robot stands approximately 1.5 meters tall, weighs 89 kilograms, features 28 degrees of freedom, and can perform dynamic movements that were science fiction a decade ago. Tesla claims its Optimus robot will achieve commercial deployment...
