The score comes from our model.

• Show HN: Cerebellum – small model on the robot, big model for what it can't undo · score 6.5

  Cerebellum is an open-source decision layer for robot fleets that routes each action by its reversibility: a small on-device model handles fast, safe decisions while NVIDIA Nemotron in the cloud approves irreversible or uncertain ones. It journals decisions locally in SQLite for offline resilience and runs one server/dashboard for the whole fleet. The routing-by-reversibility concept and NAT-friendly robot sync are a thoughtful combination, though the project is early-stage (3 stars) and tied to a hackathon demo.

• Show HN: I turned a $4 toy robot into an AI companion with one web page · score 6.3

  A maker project that repurposes a cheap toy robot into an AI companion using an Android phone as the body and a Node.js server as the brain. It combines WebUSB motor control, cloud speech/chat models, and a fine-tuned 0.8B reflex model for low-latency commands. The detailed documentation and hardware hacking make it an interesting but niche project.

• Show HN: 3D-printed bipedal robot with 8-servo limit to teach robotics · score 5.7

  Nix Robot is a 3D-printed bipedal robot with 8 servos and 10 degrees of freedom, designed as an educational platform for learning robotics. The project provides open CAD files and a partial codebase, but full build instructions and source code are only available through a paid book, limiting its openness.

• Show HN: 27B open model to grade robot data 48x cheaper/27x faster vs. 6 Astra · score 5.3

  RoboJev appears to be a 27B parameter open-weight model for automatically grading robot task success from videos, replacing manual human labeling. The claim of 48x cheaper and 28x faster labeling is interesting for robot learning pipelines, but the provided content is only a tweet with no technical details, weights, or code.
