Engineers have spent billions teaching robots to do backflips and solve complex math, yet a wet, mossy hill can stop a state-of-the-art robot completely. This video breaks down how researchers solved that problem not with better software, but by copying the design of a mountain goat's hoof, using a rigid outer shell to mimic keratin and a soft flexible core to mimic the natural grip pad, creating a robotic foot that uses zero cameras, sensors, or microprocessors. The result is a purely mechanical solution called passive mechanics, proving that sometimes evolution has already engineered the answer millions of years before we did.

This is the first movement test with the assembled prototype. The motion is still rough and the wiring is currently a complete mess, but all the connected joints are finally moving — so naturally, I made it dance. Next: smoother trajectories, control tuning, and proper cable management. submitted by /u/Ok_Stress3654 [link] [Kommentare]

I am looking for reviews or experience reports with the agilex Nero robot arm! I want to use it as a mobile manipulator, it's quite interesting given it's rather low price and high payload. [Link](https://www.mybotshop.de/AgileX-Nero-7-DoF) submitted by /u/Zarrov [link] [Kommentare]

Hey r/robotics ! After months of design and testing, I finally have a working 5-axis robot arm fully printable in PLA or PETG — no CNC, no laser cutter, just your printer. Here's what makes it different: - 5 axes (shoulder, elbow, wrist, gripper + base stepper motor) - ESP32 brain — totally open-source firmware - Electronics BOM under $100 sourcing parts yourself - Full wiring diagrams, assembly guide, and source code included The V1 is already fully operational and tested. I just launched a Kickstarter pre-launch page to fund the V2 (better rigidity, internal cable routing, improved gripper). Happy to answer any questions about the design choices, print settings, or the electronics. AMA! https://www.kickstarter.com/projects/pancoarmmk01/panco-arm-mk-01 submitted by /u/ConferenceFew7697 [link] [Kommentare]

Real robot, two arms, 1x speed. The task is deliberately reactive: the puck keeps moving, so a policy that only maps the current camera frame to a motor command tends to lag a fraction of a second and lose it. The approach on screen is a predict-then-correct loop. Rather than going straight from camera to action, the policy predicts how the scene will move over the next moments, acts inside that predicted future, then re-grounds on each real frame that arrives so it does not drift. That is what keeps it in sync with a fast target. The model behind it is LingBot-VA 2.0, a video-action policy. Genuinely curious what people here make of the world-model-first framing (predict the near-future scene, then act on it) versus a plain reactive VLA with enough data.

Researchers at UC San Diego built a humanoid robot controlled remotely by a surgeon that allows it to perform real laparoscopic surgery using standard surgical instruments by translating the surgeon's hand movements into precise robotic actions inside the body. The system was evaluated through benchtop testing, user studies across surgeons of varying experience levels, and successfully performed live laparoscopic gallbladder removal surgery, marking one of the first demonstrations of a general-purpose humanoid robot completing an actual surgical procedure rather than a dedicated purpose-built surgical system. The study also identifies key technical gaps that remain before humanoid robots can match the precision and reliability of established platforms like the da Vinci Surgical System.

I’m really hoping you all think robot mowers belong in the group for discussion. If not please delete. I’m curious people that are in to robotics is robot lawnmowers and robot vacuums something your interested in! I love both. If you have this mower or looking into getting one please ask the questions. Thanks Matt submitted by /u/mattsrobotics [link] [Kommentare]

My new video on building a low-cost autonomous robot is out: how to set up the robot hardware so it's fully ready to drive. It shows how to set up the electronics in the Viam Rover, wire in and mount the Radxa X4 with custom breadboard electronics, and attach the RealSense depth module and external battery. Take a look! https://youtu.be/EDS5Ni4JcXw submitted by /u/mikelikesrobots [link] [Kommentare]
