One professor at the University of Bonn quietly put his entire robotics curriculum on YouTube: SLAM. Sensor fusion. State estimation. Probabilistic robotics. Self-driving cars. Motion planning. Photogrammetry. Cyrill Stachniss has been uploading full university lectures for years! Each topic is a complete playlist; the kind of material that normally costs a semester of tuition. He's one of the most cited researchers in mobile robotics and mapping. His students go on to build the navigation stacks powering real autonomous systems. If you're serious about understanding how robots know where they are... this is the place to start. Free. On YouTube. 📌 [youtube.com/@CyrillStachniss] —— Weekly robotics and AI insights.

First FreeCAD book copy received! Recently, I have published the FreeCAD Beginner's Handbook and have now received my first own copy. This moment is the result of a lot of ups and downs and is one of the biggest projects of my entire life. I hope you like it. #MadeWithFreeCAD

This sounds way too advanced for our time 😮

Swiss researchers have introduced a technology that sounds like science fiction: a crystal-based battery capable of generating power for centuries without needing to recharge. Built using stable crystalline structures and radioactive decay energy capture, the battery releases a slow, consistent electrical output for hundreds of years. Unlike traditional batteries, it doesn’t degrade, leak, overheat, or lose capacity. Early prototypes show enormous potential for spacecraft, medical implants, AI sensors, underwater systems, and deep-earth machines — devices where replacing a battery is nearly impossible. If scaled, this invention could redefine global energy infrastructure, powering the future with a device that outlives generations.

I was making slides for a conference I will present a paper, and I have to say that PowerPoint is letting me down more and more. It used to be the gold standard for me to make slides, but the online version lacks so many (basic) features. 😩

Desktop version is not available for Linux. What I am missing this time, automatically going to the next slide after x seconds, and automatically starting a video when the slide appears... How can this last feature not be available?

I'm observing a mini Moravec's paradox within robotics: gymnastics that are difficult for humans are much easier for robots than "unsexy" tasks like cooking, cleaning, and assembling. It leads to a cognitive dissonance for people outside the field, "so, robots can parkour & breakdance, but why can't they take care of my dog?" Trust me, I got asked by my parents about this more than you think ... The "Robot Moravec's paradox" also creates the illusion that physical AI capabilities are way more advanced than they truly are. I'm not singling out Unitree, as it applies widely to all recent acrobatic demos in the industry. Here's a simple test: if you set up a wall in front of the side-flipping robot, it will slam into it at full force and make a spectacle. Because it's just overfitting that single reference motion, without any awareness of the surroundings. Here's why the paradox exists: it's much easier to train a "blind gymnast" than a robot that sees and manipulates. The former can be solved entirely in simulation and transferred zero-shot to the real world, while the latter demands extremely realistic rendering, contact physics, and messy real-world object dynamics - none of which can be simulated well. Imagine you can train LLMs not from the internet, but from a purely hand-crafted text console game. Roboticists got lucky. We happen to live in a world where accelerated physics engines are so good that we can get away with impressive acrobatics using literally zero real data. But we haven't yet discovered the same cheat code for general dexterity. Till then, we'll still get questioned by our confused parents.

Star Wars showed them to you in ‘77. You grew up watching robots on screen. But what if you could actually buy one? For your lab. For your classroom. For your... kid. A French startup made it real, and affordable:🧵

Let me introduce more details about our new quadruped robot, KLEIYN. This robot is capable of chimney climbing on walls of various widths, like Ninja! I will explain its design and learning methodology. Thread👇

This announcement is very important for robotic startups. USB is unreliable on real-world product and having a RealSense camera with Power over Ethernet is great! intelrealsense.com/depth-cam…
