I put my CFD lecture notes online, because apparently “just vibe with Navier-Stokes” is not a stable numerical method smh
Finite differences, flows, schemes, and assorted computational fluid chaos here: github.com/jaiselsingh1/N…
in memory of the good ol blackboard sessions heh

You know the researchers are absolutely passionate when you see such quotes in the paper

1/ We just released π0.7 — a steerable generalist robot model with emergent capabilities. I want to share a bit of the backstory, because π0.7 taught me something surprising about where robot learning is heading. A thread on bittersweet lessons 🧵

We are excited to share our #ICRA2026 paper "Dream to Fly: Model-Based Reinforcement Learning for Vision-Based Drone Flight"!
Paper: rpg.ifi.uzh.ch/docs/ICRA26_Ro…
Video: youtu.be/nctQ2rxZnIc
Can we use Model-Based #ReinforcementLearning (MBRL) to fly a drone from pixels to commands? In this work, we train quadrotor navigation policies from scratch using #WorldModels, mapping raw onboard camera pixels directly to control commands, much like a human pilot!
While model-free methods like PPO are sample-inefficient and struggle in this setting, we leverage #MBRL to train visuomotor policies capable of agile flight through a racetrack using only raw pixel observations, no explicit state estimation needed.
A key finding: because our policies are trained end-to-end directly from pixels, we no longer need the perception-aware reward term used in previous methods. Instead, this behavior emerges naturally! The policies learn to guide the camera toward feature-rich areas of the observation space on their own.

@ETtech Pick & place use case I believe. I hope they intend to spend money on data collection & not fall into the trenches of building a foundational model.

I've been to Shenzhen annually since 2023, so I created a map of the shops worth visiting in the electronics district: docs.google.com/presentation/d…

Really excited to release mjviser, a web-based MuJoCo viewer, powered by Viser. It has almost all the features of the native MuJoCo viewer, but runs in your browser. Load and simulate any MuJoCo model with a single uv command 👇

engineering is when robot form follows function
ObotX - Open Source Robotics@open_robotx
Our blueprint for the "Optimal Universal Robot": ❌ Legs: Too complex, too expensive. ✅ Wheels: Fast, stable, 10x cheaper. ❌ Rotary Joints: Massive torque stress, custom gears. ✅ Of the shelf parts & linear actuators: High payload, extrem simplicity, off-the-shelf parts.
