Modular robots that repair themselves by... stealing parts! 👀 A team at Columbia University built robots made of Truss Links, stick-shaped modules with magnetic connectors at each end. Connect a few and you get a structure that can expand, contract, roll, and reshape itself. If a link breaks or comes loose, the robot grabs a spare module nearby and rebuilds itself. No human intervention needed. A tetrahedron-shaped robot grabbed a spare link like a walking stick. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

A 40-year-old patent has finally been brought to life. That's the Y-zipper. A 3D-printed three-sided fastener that transitions any object from flexible to rigid and back again. The robotics application is the one that caught my attention. A quadruped robot that adjusts its leg stiffness depending on terrain, switching between rigid and flexible in real time without additional motors or complex mechanical systems. But this goes way beyond robotics. A wrist cast that loosens during the day and stiffens at night. A tent that pops into shape in 90 seconds instead of six minutes. The idea sat in a patent filing for four decades. It took 3D printing to finally make it real. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Your phone can build voxel world now! 👾 This is an open-source tool that converts phone video into 3D point clouds. You can run Depth Anything 3 locally. Basically just local GPU inference. The interesting part is how it handles messy input. Video windows overlap, scale gets converted to real meters, drift gets corrected after inference. The system stitches everything together even when footage is noisy. Objects far away might fail strict confidence filters but still show up as recognizable buildings. That's huge for small robots because perception becomes cheap and stays local. Obviously it wouldn't be a phone for robots, but it shows the potential of edge/local perception processing. A robot can understand its environment without offloading to the cloud. Real-world video has artifacts and occlusions. The system doesn't need perfect input to reconstruct scene structure. It works with what's there. For robotics, this means small platforms can build 3D maps autonomously using hardware they already have. Here's the repo: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

A humanoidal welder! 👨🏼🏭 Persona AI deployed their humanoid to a real welding facility in Houston and executed an actual weld. All of that in a hot-work industrial environment with arc flash, smoke, and uneven flooring. The robot squats down, executes the weld with a steady arc, stands back up. Functional welding requires multi-joint precision, spatial awareness, and real-time path correction. The robot had to hold a lit torch, maintain arc stability, and lay down a valid weld path. The motion is choppy. They're honest about that. But they proved the robot can handle the full sequence that actual industrial work demands. Get low, do precision work, stand up, move to the next spot. That's the rhythm of real welding jobs. Teleoperation is their training method. VR headset interface captures expert demonstrations. Those become the data to train neural networks toward eventual autonomy. This is what deploying into real facilities means. That's a nice one gents Nicolaus Radford!

Autonomous tractor from Netherlands! 🇳🇱 Despite all the narrative, we are still building awesome companies in hardware space in Europe. Recently, I've posted about a Chinese autonomous tractors company. So today I wanted to show something that was created in the middle of Europe. This is a fully autonomous tractor from Dutch company AgXeed, designed to work on fields without any human supervision. It's powered by a diesel engine that drives a generator, which then powers electric motors driving the tracks. The fuel tank allows for 24 hours of continuous operation. (nice!) The rear hitch has an 8-ton lift capacity, the front has 3 tons. It's equipped with electric PTO, hydraulic pump, and all the connections you'd find on a traditional tractor, meaning you can attach standard farm implements. (nice! x2) Safety and navigation are handled by a LiDAR sensor on top, ultrasonic and radar sensors, and contact-sensitive bumpers. RTK GNSS receiver provides positioning accuracy down to 2.5 cm. Love seeing that so many companies are trying to make farmer's life easier! What are the others companies building in agri-tech? I want to meet them! 👀 ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Engineering excellence through destruction! 💥 Dyson's testing philosophy is to break it until it fails, then rebuild it better. Vacuum batteries go through 1,200 charge/discharge cycles, the Supersonic hair dryer cable gets wrapped and unwrapped 7,800 times, Corrale straightener plates open and close 400,000 times, and purifiers run 24/7 until they fail. By testing to failure, Dyson discovers the exact limits of materials, mechanisms, and electronics before the product ever reaches a customer. Dyson tests until things break, studies why they broke, then redesigns around those failure modes. It's the same principle behind Tesla's rapid iteration on Starship (blow them up until you understand what fails). The difference between "it works" and "it lasts" is understanding failure modes. This is what separates consumer products that last 2 years from ones that last 10. The engineering discipline to destroy your own work, learn from it, and build the next version smarter. P.S. Would love to see more robotics companies adopt this level of durability testing. Most demos show success. Few show the 400,000 cycles of wear that prove it actually works. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

A drone or a submarine? 🫧 A student just built a drone that flies through the air and swims underwater — and it actually works. As part of his Bachelor’s project, Andrei Copaci created a 3D-printed, hybrid drone with variable pitch propellers, meaning the blades shift mid-flight to adapt between air and water. Just a laptop, a printer, and a smart idea. The drone is fully custom-coded and transitions seamlessly between flying and swimming. We're entering a new era, where curious students can prototype what once took massive funding and R&D efforts.

Precision robots for electronics and lab automation! 🧪 Mecademic makes robots that do two things simultaneously, manipulate material and move it. They're not competing with the big legacy robot manufacturers. They're smaller, more nimble, and obsessively precise. Their niche? Electronics manufacturing and lab automation. Why? Repeatability and precision. 5 microns. That's 5/100 of a human hair width. When you command the robot to point X, it goes to point X every single time with almost zero offset. That’s really important for electronics because tolerances are tight. Components are small. A few microns of error compounds into failure. Lab automation needs the same thing, exact positioning for liquid handling, sample processing, reagent dispensing. It was awesome to see their booth at Automate Show in Chicago. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Unloading trucks with robots! 📦 Bastian Solutions has developed a mobile robot system that automates high-volume, floor-level unloading of trailers. Let's have a closer look at how it actually works! The robot seamlessly drives itself in and out of trailers and docks without any fixed infrastructure. This system picks up cases via an extendable conveyor, lifts them using a retractable mast, and accurately places them inside the trailer using a dedicated gripper. In the video you can see the reversed process, unloading of a truck. 🚛 It's guided by LiDAR-based navigation and an omnidirectional base, enabling fast, precise, and infrastructure-free operation. Integrates smoothly with existing systems like conveyors, scanners, sorters, and depalletizers. Every time I see a robot loading and unloading a truck, I'm like: we are getting there :) ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Magnetic levitation for surgical robots! 🧲 A research team working on minimally invasive surgery just introduced a remote magnetic levitation to move things inside our bodies. Their main goal is to control guidewires and catheters inside the body using magnetic fields. But levitation is unstable and extreme, it forces them to solve fundamental control problems they can't avoid. They have to handle strong magnetic field nonlinearities, develop real-time invertible models, and create control methods that work on any eMNS (electroMagnetic Navigation System) and any object. The real challenge is the position and orientation feedback. You can control a magnet outside the body, but once a catheter or drug-delivery robot is inside a patient, you can't see it. There's no vision, but just magnetic fields and current measurements. That's huge news coming out of ETH Zurich! Here's the paper: Mentioned all authors on Li, but coulnd't find them here! ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Welcome to the pico world! 🔬 Micro-dispensing at the picoliter scale is incredible when you compare it to everyday numbers: a single raindrop is about 50 microliters, roughly 50 million times larger than a picoliter. Being able to place droplets this small without touching the surface is key for biotech, diagnostics, and micro-electronics, where tiny volumes matter. And at this scale, two basics become critical: → Accuracy = how close you are to the real value. → Precision = how repeatable each droplet is. I could watch it all day long! 🤯 ~~ ♻ Join the weekly robotics newsletter, and never miss any news →

Open-source magnetic tactile sensor for $5! 🧲 Researchers introduced a magnetic tactile sensor that's low-cost, and easy to fabricate, democratizing tactile sensing for robotics. Operating in unstructured environments like homes and offices requires robots to sense forces during physical interaction. Yet the lack of a versatile, accessible tactile sensor has led to fragmented solutions and often force-unaware, sensorless approaches. Building an eFlesh sensor requires four components: a hobbyist 3D printer, off-the-shelf magnets (less than $5), a CAD model, and a magnetometer circuit board. The sensor is 3D printed with magnets embedded in the middle layer. Based on chosen mechanical properties, magnets displace in response to contact forces, measured by a magnetometer underneath. An open-source design tool converts simple OBJ/STL files into 3D-printable STLs. This enables application-specific sensors for robot hands, grippers, quadruped feet, and more. Slip detection generalizes to unseen objects with 95% accuracy. Visual-tactile control policies improve manipulation by 40% over vision-only baselines, achieving 90% success on precise tasks like plug insertion and credit card swiping. All design files, code, trained models, and conversion tools are openly available. Project page: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

This drone becomes a flying manipulator! 🥏 Researchers at the The University of Tokyo developed this aerial robot. Built with four pairs of ducted fans linked by actuated joints, Dragon can reshape itself mid-flight. This allows it to grasp objects and perform tasks typically reserved for ground-based manipulators. Each segment has dual rotors, and its navigation stack calculates the most efficient shape for each object. Total payload? More than 3 kilograms. P.S. To increase Dragon's battery life, they consider allowing it to walk on the ground.
