Top AI Product

XiaoRGEEK shipped a 22-DOF desktop biped for $1,565. Unitree R1 starts at $20K. That gap is the story.

A 22-DOF biped on a Pi 4

Brain is a Raspberry Pi 4. Body is a 2.3 kg aluminum frame with 22 high-voltage bus servos — every joint has overheat, overvoltage, and stall protection, which matters when your $1.5K toy faceplants on a desk. Vision is a 1080p wide-angle cam on a 2-DOF gimbal. Stack is Ubuntu 18.04 plus ROS Melodic, the same distro academic robotics labs ship papers on. Top SKU lands at $2,019. Target buyer: RoboCup teams and embodied AI researchers who can’t justify a $20K Unitree.

ROS-native, agent-ready

This is the part for anyone building physical AI agents. SamuRoid ships Python and C++ SDKs plus RoboManager for drag-drop motion programming. DeepSeek, Doubao, and Qwen are pre-wired for vision, speech, and reasoning. Because everything rides on ROS topics and services, you can hand control to any agent framework — LLM plans the task, fires ROS commands, watches the camera feed, retries on failure. Pick-and-place, line-following, and person-tracking demos already exist. CNX Software broke it 2026-04-22; Hacker News and r/robotics ran the same week.
