Excited to share that TinyNav now has an app! We’re making robot navigation more accessible for everyone. More updates are on the way—stay tuned.

Insight 9 SLAM Robustness Test 🎥
We put our AI-native spatial camera through rapid, dynamic movements. Watch the right screen: TinyNav VSLAM trajectory in RVIZ stays perfectly stable. 24G accelerometer & 188° ultra-wide FOV = zero tracking loss.#SLAM #Robotics #EmbodiedAI #VSLAM

FoundationStereo >> FastFoundationStereo > Retinify
Mar 26
We expected FastFoundationStereo to be close to FoundationStereo. We were wrong.
On Jetson Orin Nano:
- FoundationStereo surprised us — lidar-quality point cloud
- FastFoundationStereo is far worse (yes, it is indeed fast)
- Retinify matches FastFoundationStereo's quality but is faster
Speed: 100ms vs 15ms.
Our fork fixed the 2-stage ONNX export with custom TensorRT plugins → single ONNX/plan.

Tuned a faster Harris frontend kernel on an A55 ARM CPU @ 1.5GHz.
For 752×480 EuRoC frames:
• 59.49 ms → 21.51 ms
• 2.77x faster Harris
Same output:
• 159 detected points
• 139 tracked points
Pipeline runtime:
• 68.43 ms → 43.20 ms

If you know your hardware well enough, you can still write code that's faster than today's AI. I wrote a Harris corner detector kernel that's 2× faster than OpenCV.

Just updated it to include frontend benchmarks. The first version compares Harris Optical Flow with ORB Hamming matching.
Keep watching: github.com/dvorak0/slambench
You can also easily reproduce the test with:
docker run --rm --cpuset-cpus="0" uniflexai/slambench:latest

Thanks for open-sourcing such great models. In our early test, Fast Foundation Stereo reached real-time performance (>13.5 FPS) with max disparity 64 on Jetson Orin NX — honestly much better than we expected.
We’re planning to integrate it into our open-source navigation stack soon:

Enjoy!

I’ve updated github.com/dvorak0/slambench with more benchmark results, including row-major vs column-major comparisons and GTSAM SmartFactor benchmarks.
Added a summary screenshot below — check it out!

Working on SLAM for years, I’m constantly asked: which method is faster?
So I made a one-line command to benchmark solver speed with the standard dubrovnik/problem-16-22106-pre.txt input:
`docker run --rm uniflexai/slambench:latest`
Run it, share your result, and tell me if anything looks unexpected.

Is it just me or are these robots getting TOO real? 🤖
Caught this @UnitreeRobotics dog zooming past. That new sensor rig looks like giant shades 🕶️. Scary smooth gait.
Is this a secret field test? 🤯🔥 #Robotics #Unitree #TechLeak #FutureIsHere #Spotted

saw completely new design of the head. @UnitreeRobotics is going to navigate the robots using stereo camera, just like our open source project tinynav github.com/UniflexAI/tinynav

WTF is this?? Just saw this robot walking in the park lol. Is this a new Unitree model or what? I’ve never seen this head design before, like it’s wearing futuristic giant sunglasses. Probably some crazy new cameras inside? Anyone know? New leak? #Robotics #Unitree #TechLeak

Excited to share a video about the workflow of our project!
From zero to navigation with TinyNav 🗺️➡️🤖
1️⃣ Build a map
2️⃣ Add POIs in the editor
3️⃣ Let your robots navigate, correctly react to obstacles, and find feasible paths
Keep an eye on TinyNav — a ~3,000-line open-source navigation stack for multiple robot platforms 🚀
We’ve added a remote interface using @foxglove — an amazing tool. Thanks, Foxglove 🙌 #Robot #Unitree #navigation

We need re-consider our stereo model! I will report the difference soon in our project.

A new milestone for real-time accurate 3D spatial computing! Introducing ⚡️Fast-FoundationStereo⚡️, a real-time zero-shot stereo depth estimation model that accelerates the original FoundationStereo by >10x with comparable quality.
