Just coming back from NeurIPS, last one I went to was in 2022. Kinda shocked at the amount of research that was essentially just fiddling with existing large models. Really sad stuff.

This is my whole point- the locomotion looking “solved” is a mirage. All they can do is playback prerecorded references, but the method being shown isn’t steerable. As currently demonstrated, you can’t use that run for useful work at all. It’s just a slick demo.

Currently most bots locomotion and manipulation are too slow to be useful. Now that locomotion looks solved the hard part starts: manipulation

1/5 Humans are able to look at their surroundings and pinpoint their location on a map, even for totally new buildings. Can computer vision systems do the same? 🤖🗺️ We explore this In our #NeurIPS2025 paper - C3Po: Cross-View Cross Modality Correspondence by Pointmap Prediction.

Robot learning people suddenly realizing that SLAM/VIO being the biggest moat for data collection was in fact in my bingo card for 2025/2026.

my friend was a software engineer, got laid off in 2022, couldn’t find a job for 3 years, & is now going back to school in a different field 😔 it’s tough out here

Nicolas Mansard: in locomotion / legged motion, when we worked on MPC (model predictive control) we were a team of 10 working on the robot and it barely worked. Now with RL (Reinforcement Learning) a single student can get a policy in 3 months, including training of the student.

SLAM for large-scale scenes Accurate visual geometry estimation improves SLAM performance. DA3 significantly reduces drift in large-scale environments, even better than COLMAP, which takes more 48 hours to complete. 👇(3/n)
