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 →

That's how parts get inspected! 🪡 The pace is ridiculous. Imagine people still doing this instead of machines. Renishaw system is one of the biggest shifts in coordinate-measuring machines (CMMs). Instead of moving the entire machine to capture each point, REVO uses a 5-axis scanning head that collects data through rapid angular motion. Combined with automated probe and stylus changes, the system can handle complex geometries and full surface scans that traditionally required slow, point-by-point probing. ~~ ♻️ 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 →

A robot with 20 legs! 🐛 Duke University researchers published a study presenting a sea-urchin-like robot with 20 legs. The robot, called Argus, has no front or back. Twenty telescoping legs radiate from a central body, with a depth camera at each leg tip. The design allows it to move in any direction, stabilize after being pushed, cross rough terrain, carry 10-pound payloads, and even climb walls. The researchers didn't ask "what animal should we copy?" Instead, they focused on a mathematical concept called dynamic isotropy, how symmetrically a robot can accelerate in every direction. A score of 1 means perfect symmetry in all directions. Most robots today, including advanced quadrupeds and humanoids, score below 0.6. Argus scored 0.91, close to theoretical maximum. How? They arranged the body around a regular dodecahedron (a shape with 12 pentagonal faces), giving Argus a nearly uniform field of view and eliminating the need to orient itself the way conventional robots do. When tested on uneven ground, concrete, grass, sand, wet surfaces, Argus handled obstacles, kept moving with broken legs, and pushed heavy objects while rolling.

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.

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 →

It's a 3D printer, and 3D assembly station! 🖨️ The Functgraph developed at Meiji University starts as a regular 3D printer but upgrades itself into a mini factory. It can print parts for its own tools, pick them up, clean them, and put them together, all by itself. Think of it like a robot that can 3D print a spatula, assemble it, and then use it to flip pancakes. 🥞 Instead of just printing objects, the Functgraph can actually perform physical tasks, like folding laundry or slicing vegetables, by using printed and assembled tools. It’s a step toward the idea of a robot that can download "apps" as physical skills, much like your phone downloads software! 👀 ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

74 seconds to print a 3D Benchy! 🚢 Someone just printed a 3D Benchy in 74 seconds! For context: Benchy is the standard benchmark for 3D printing quality. Getting it done in 74 seconds required pushing every variable to its limit. Pulley and belt systems optimized for minimal slop, machine rigidity improvements to eliminate flex under high acceleration, input shaping to cancel out resonance frequencies that cause ringing artifacts at high speeds. A 3D scanner to analyze print quality objectively. Frequency analysis to identify and cancel specific resonance modes in the frame and motion system.

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.

3D printing is getting wild! 🧊 A one-piece printed bar counter just dropped: 1.1 meters tall and over 4 meters long, made entirely from PETG with millimeter-level precision. A single continuous organic surface with integrated LED backlighting. A giant monolithic print. Every week we’re seeing 3D printers take on bigger, more complex, more architectural pieces. And this one shows just how far large-format additive manufacturing has come. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

JUST IN: microagi is opening its Global Robotics Research HQ on Bahnhofstrasse in Zürich, and choosing it over San Francisco. Eight months ago microagi was five people in a Munich hacker house. Today they operate in 15+ countries. The reasoning behind Zürich is compelling: → Highest density of robotics talent in the world, ETH Zürich, EPFL, University of Zürich, IBM Research, Google, NVIDIA, Meta, Apple and Microsoft all run serious ML and robotics teams here → ABB, one of the most important industrial automation companies on earth, is headquartered in the city itself → Within a 6-hour radius: German automotive, Italian manufacturing, French aerospace, Benelux logistics and Swiss machine tools But the line that stuck with me most: "Europe was late to consumer internet. Europe was late to cloud. Europe was late to the foundation-model wave. But Europe is not late to robotics." That is exactly right. The industrial base that physical AI sits on top of has been in Europe for 150 years. Precision mechanics. Machine-tool culture. Safety-critical engineering. Automation-grade manufacturing. The next decade of AI value will be created where bits meet atoms. And Europe is finally in the right position at the right moment. microagi gets it. And they're planting their flag right in the heart of it. 🇨🇭🇪🇺 Bercan, Yoan Iliev, Zeno, Gianni Hodel LFG! 🔥 ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Gravity-defying robot! 🦎 VertiGo is a wall-climbing robot created by Disney Research and ETH Zürich that can transition between ground and wall. The robot can move on a wall quickly and with agility. VertiGo has four wheels, two tiltable propellers, and two tiltable propellers. One pair of wheels is steerable, and each propeller has two degrees of freedom for adjusting the direction of thrust. The choice of two propellers rather than one enables a floor-to-wall transition, thrust is applied both towards the wall using the rear propeller and in an upward direction using the front propeller, resulting in a flip onto the wall. P.S. Can you guess the year of development? 👀 ~~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Engineering through destruction! 🔨 Dyson's testing philosophy: break it until it fails, then rebuild it better. Here's what that actually means in practice: 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 system with moving transfer plates! 🍽️ Modular transfer plates that move items in any direction! These systems from Festo give factories something traditional conveyors can’t: fine, reconfigurable motion that adapts as layouts or processes change. Because they can route items in multiple directions, you can run inspections, branch flows based on sensor data, or perform operations directly on the moving parts. It could even power fully automated storage: shelves that reposition items based on real-time demand. I'd love to see more of them in 3PL centers. Where would you use them? 👀 ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →
