Nori Robotics (YC S26) – A low-cost humanoid robot for development: VALIDATE, 72/100 | Ideas Lab

A $1,688 humanoid robot designed to democratize robotics research by making hardware affordable enough for labs and developers to own multiple units for dataset collection and experimentation.

The pain

Robotics researchers and developers face a hardware bottleneck: expensive robots ($50k-$150k+) mean labs own only one or two units, making it impossible to collect large datasets, run parallel experiments, or test algorithms across multiple robots. This slows down AI/robotics progress and locks out smaller teams and individual developers.

The gap

The market has expensive research robots (Boston Dynamics, ABB) and toy robots, but nothing in the $1,500-$2,500 range that's actually capable of real tasks (manipulation, mobility, sensing) and designed for iterative development. Nori fills this gap with a purpose-built platform that trades some performance for affordability and repairability.

Build angle

Start with robotics researchers and university labs as the beachhead. They have budget, understand the value proposition, and can generate word-of-mouth. Build a community around shared task demonstrations and open-source models. Revenue comes from hardware sales initially, then potentially from a marketplace for trained behaviors or cloud compute for running larger models. The open SDK and simulator lower friction to adoption.

Strengths

Solves a real, specific problem for a defined customer segment (researchers) with clear ROI (cheaper than one expensive robot)
Founder has domain expertise (Columbia robotics research) and built seven iterations, not first-time hardware
Already shipped first unit and has working demos (cleaning, drawer opening, shelf restocking)
Open SDK and browser simulator reduce adoption friction and build community
Designed for manufacturability and repairability, which matters for unit economics at scale
19 DOF with dual arms is genuinely capable, not a toy
YC backing provides credibility and network for B2B sales to labs

Risks

Hardware businesses have brutal unit economics; $1,688 price point leaves little margin for manufacturing, support, and overhead. Needs to hit 40%+ gross margins to be viable long-term
Competitive threat from larger robotics companies (Tesla Bot, Boston Dynamics, Figure) moving downmarket with better capital and supply chains
Customer acquisition for B2B hardware is slow and expensive; university sales cycles are 6-12 months
Raspberry Pi 5 with 4GB RAM is a constraint; heavy models must run on external servers, creating dependency and latency issues for real-time control
Servo-based actuation (vs. QDD motors) may limit precision and durability for repeated manipulation tasks; long-term reliability unknown
Market size is limited to researchers and developers; consumer/commercial applications (cleaning, restocking) are mentioned but not the core go-to-market
Supply chain risk: 100+ parts per unit means any component shortage cascades; assembly in SF is expensive and doesn't scale

Semble – Code search for agents that uses 98% fewer tokens than grep

Hey HN! We (Stephan and Thomas) recently open-sourced Semble. We kept running into the same problem while using Claude Code on large codebases: when the agent can't find something directly, it falls back to grep, reading full files or launching subagents. This uses a lot of tokens, and often still misses the relevant code. There are existing tools for this, but they were either too slow to index on demand, needed API keys, or had poor retrieval quality.Semble is our solution for this. It combines static Model2Vec embeddings (using our latest static model: potion-code-16M) with BM25, fused via RRF and reranked with code-aware signals. Everything runs on CPU since there's no transformers involved. On our benchmark of ~1250 query/document pairs across 63 repos and 19 languages, it uses 98% fewer tokens than grep+read and reaches 99% of the retrieval quality of a 137M-parameter code-trained transformer, while being ~200x faster.Main features:- Token-efficient: 98% fewer tokens than grep+read- Fast: ~250ms to index a typical repo on our benchmark, ~1.5ms per query on CPU (very large repos may take longer)- Accurate: 0.854 NDCG@10, 99% of the best transformer setup we tested- MCP server: drop-in for Claude Code, Cursor, Codex, OpenCode- Zero config: no API keys, no GPU, no external servicesInstall in Claude Code with: claude mcp add semble -s user -- uvx --from "semble[mcp]" sembleOr check our README for other installation instructions, benchmarks, and methodology:Semble: https://github.com/MinishLab/sembleBenchmarks: https://github.com/MinishLab/semble/tree/main/benchmarksModel: https://huggingface.co/minishlab/potion-code-16MLet us know if you have any feedback or questions!

Postgres extension for BM25 relevance-ranked full-text search

Last summer we faced a conundrum at my company, Tiger Data, a Postgres cloud vendor whose main business is in timeseries data. We were trying to grow our business towards emerging AI-centric workloads and wanted to provide a state-of-the-art hybrid search stack in Postgres. We'd already built pgvectorscale in house with the goal of scaling semantic search beyond pgvector's main memory limitations. We just needed a scalable ranked keyword search solution too.The problem: core Postgres doesn't provide this; the leading Postgres BM25 extension, ParadeDB, is guarded behind AGPL; developing our own extension appeared daunting. We'd need a small team of sharp engineers and 6-12 months, I figured. And we'd probably still fall short of the performance of a mature system like Parade/Tantivy.Or would we? I'd be experimenting long enough with AI-boosted development at that point to realize that with the latest tools (Claude Code + Opus) and an experienced hand (I've been working in database systems internals for 25 years now), the old time estimates pretty much go out the window.I told our CTO I thought I could solo the project in one quarter. This raised some eyebrows.It did take a little more time than that (two quarters), and we got some real help from the community (amazing!) after open-sourcing the pre-release. But I'm thrilled/exhausted today to share that pg_textsearch v1.0 is freely available via open source (Postgres license), on Tiger Data cloud, and hopefully soon, a hyperscalar near you:https://github.com/timescale/pg_textsearchIn the blog post accompanying the release, I overview the architecture and present benchmark results using MS-MARCO. To my surprise, we were not only able to meet Parade/Tantivy's query performance, but exceed it substantially, measuring a 4.7x advantage on query throughput at scale:https://www.tigerdata.com/blog/pg-textsearch-bm25-fu

Consus (YC F24) – LLM gateway for companies handling sensitive data

Hey Hacker News! I'm Eric, the founder of Consus. We route all AI requests to ITAR restricted and controlled unclassified information (CUI) compliant infrastructure. Consus itself satisfies ITAR restrictions, and we recently completed our FedRAMP equivalency audit against the 410 FedRAMP High controls. FedRAMP High is the U.S. government’s strictest security baseline for cloud services handling sensitive unclassified data. A breach of this data could cause severe or catastrophic harm. Achieving FedRAMP equivalency, or authorization, is required before processing CUI information.Demo: https://youtu.be/6MYxJe6P4oYAerospace and defense is experiencing rapid growth. Unfortunately, most companies are struggling to use AI because of necessary data protections & compliance risk. These companies can move even faster if they could use the AI tools that most other industries take for granted.I spent most of my career prior to Consus in aerospace & defense. I launched national security payloads at SpaceX, and was an early employee at Castelion. I’ve watched first hand how compliance red-tape makes it difficult for companies to adopt new technologies and trust vendors that touch their sensitive data. For example, I worked with a satellite manufacturer that doesn’t allow any AI tools, even for non-sensitive work.Even as AI has become extremely useful over the past 9-12 months, I was surprised by how many aerospace & defense companies refused to touch it. They could see how it could be helpful, but they were scared about model providers training on their data, violating an ITAR rule, or risk losing new business because of a failed cyber assessment. These are all rational fears.There were a lot of ways to solve some/all of these problems, but we focused on building a compliant AI inference layer that can "plug" into any AI tool or workflow. Just as OpenRouter integrates with most tools, Consus can connect to tools like ChatGPT or Clau
