What a nice morning to find that Alzugaray, Taher @marwantaher.bsky.social , Davison @ajdavison.bsky.social have turned ACE into a SLAM system. Since we did ACE, I was wondering whether it was possible, and I always thought who if not those folks can pull it off. 🙂 ACESLAM: arxiv.org/abs/2512.14032

I've been a Tamiya RC fan since owning and loving a Grasshopper in the 80s, and more recently built one or their RC kits with each of my kids (Hornet, LunchBox and Midnight Pumpkin!)

Full draft of the SLAM Handbook now released --- available as a free PDF, with a printed version coming soon. Now including Part 3, "From SLAM to Spatial AI" (I knew it would catch on eventually), with contributions from @hidematsu82.bsky.social and me. #SpatialAI github.com/SLAM-Handboo...

It's 3PM. Exactly 40 years ago the first ARM processor was powered up. It worked. To mark the occasion, a bottle of champagne was opened and the time and date was written on the bottle - by Sophie Wilson IIRC. I hope today another bottle is opened to celebrate the anniversary.

We were fortunate to have Jianyuan visit us at Imperial yesterday, and he gave a brilliant and thoughtful talk about 3D geometry and learning. Maybe every 6--12 months or so there is a paper in my area which really seems like something new and important, and VGGT is one of those!

Remember: the route to Spatial AI is through SLAM. Key research topics are representations for real-time fusion of measurements and priors into persistent semantic/metric scene models; and algorithm/hardware co-design for 1000X efficiency. #SpatialAI arxiv.org/abs/1803.11288

Aria Gen 2 is very impressive, with fully onboard SLAM and various other perception all within a 75g device with an hours-long battery life. Processing on custom silicon. Congrats to the Reality Labs team.

I remember seeing this drone video a few years ago and thinking "we'll never run SLAM on that".... but here it is, complete with dense reconstruction (single camera, unknown calibration, no IMU). MASt3R-SLAM is absurdly robust.

Andrew Davison @ajdavison.bsky.social · 25/02/2025

Open source code now available MASt3R-SLAM: the best dense visual SLAM system I've ever seen. Real-time and monocular, and easy to run with a live camera or on videos without needing to know the camera calibration. Brilliant work from Eric and Riku.

Not one VC would ever fund a startup to do the kind of hardcore optimization work that DeepSeek did. Every VC firm should be asking themselves why.

Yes, software for robotics (and vision) comes and goes and in the end you'll have to build it yourself if you want to really push forwards.

Nice analogy. I'm wondering what the future of scientific publishing should be, given that LLMs are increasingly good at automatically going from full paper to summary, or vice versa. Surely we could be publishing new ideas in the "sketch" form only, but I can't quite imagine exactly what that is.

However, if the factor of distance difference is less than 2, like 10 and 8, you can indeed have a faster average for 10km. Consider a 10km ride with very fast first and last km but slow in between. Would be a weird way to ride... 3/3

130

Andrew Davison @ajdavison.bsky.social · 29/12/2024

But I was confused about if it's even possible to have a faster average speed for a longer distance. When the distance changes by a factor of 2, it's not. Take your fastest 10km segment, split it into two 5km segments, and either both will have the same average or one will be faster, one slower. 2/n

Andrew Davison @ajdavison.bsky.social · 29/12/2024

I was surprised that on Strava my best average speed for 10km was a bit faster than for 5 miles (which is shorter, about 8km). Strava automatically finds the fastest segments from any ride you've recorded. Normally of course you see a faster average speed for shorter distances. 1/n
