I have implemented gesture recognition with my dtof lidar HM-LD1, and at the same time, for better learning for everyone, I have made it open-source. Github Link: https://github.com/myrobotproject/Dtof-Lidar-HM-LD1-Gesture-Recognition submitted by /u/RiskHot1017 [link] [Kommentare]

Hey everyone! Kaushik here, built https://www.zero2robot.com/ Neural nets have Zero-to-Hero. Deep RL has Spinning Up. Robot learning never got the same thing: a path where you build the whole stack yourself, from nothing, and understand every piece. So I spent some time building it. Zero2Robot is a free, open-source interactive textbook for robot learning. You start with a blank simulation loop and build behavior cloning, diffusion, PPO/SAC, a tiny VLA, a browser demo path, and even parts of a physics engine—one runnable file at a time. Runs on a laptop or free Colab. No robot required. Do give it a try, and let me know what you think. submitted by /u/Few-Sleep2303 [link] [Kommentare]

Hey everyone! Kaushik here. I’ve been working on an open-source project called Zero2Robot: https://www.zero2robot.com/ While learning robot learning, I struggled to find a resource that built the entire stack from first principles. Many courses explain individual algorithms, but fewer show how simulation, data collection, policies, evaluation, and deployment fit together. So I tried to build the resource I wanted. Zero2Robot is an interactive textbook in which each chapter adds one working component to a small robot-learning system. It begins with a basic simulation loop and gradually covers behavior cloning, diffusion policies, PPO/SAC, a small vision-language-action model, browser-based demos, and parts of a physics engine. Everything is free and open-source, and the exercises run on a laptop or in a free Colab without requiring a physical robot. submitted by /u/Few-Sleep2303 [link] [Kommentare]

We've been iterating on SoftSync FlexHand V1 over the last few weeks. This update focuses on two mechanical improvements: Switched to a new soft material for better compliance. Combined braided reinforcement with additive manufacturing to improve durability. The demo shows thumb-to-index, thumb-to-middle, and thumb-to-ring pinch generated with a simple drag-and-drop programming workflow. No pre-training was used. I'd love to hear any feedback, especially on the mechanical design or the control workflow. submitted by /u/LSunround [link] [Kommentare]

Hello, its been a while! I want to share a bit about the journey behind my challenge of building an Open Source commercial grade humanoid robot totally alone at home. You might remember me from https://www.reddit.com/r/robotics/s/zzx9Yi4tXI. Which was my first iteration! My first iteration was honestly pretty bad. It was a beginner-level design, and many of you probably noticed it looked like something that would never actually work. Looking back, I completely agree. It lacked proper physics, kinematics, finite element analysis, and nowhere near enough structural rigidity to survive a walking gait. Everything looked fine inside a simulator, but reality was different. The robot literally broke during its very first movement. First Iteration on fusion360 looked like, yes you can make fun of it all you want but this baby tought me that you should not give up: https://preview.redd.it/7qbpdbss26dh1.png?width=972&format=png&auto=webp&s=c31061037ed50ece8dbabbd9312db2dbdee4c620 I threw it away. After that, I gave up for a few months. Life got in the way, and I stopped working on the project entirely. Eventually I came back, more motivated than ever. For months I dove deep into control theory, kinematics, mechanics, physics, electronics, energy systems, transmission systems, Actuators, FOC, Torque and robot design. That led to the second iteration of my humanoid. second iteration render on FUSION 360: https://preview.redd.it/obi18ie756dh1.jpg?width=795&format=pjpg&auto=webp&s=df46134a3e419df72d61641d5d695cc04ac9b359 ...which also failed. 😂 Why it failed? The whole design was just bad, i wasn't using the motors case for anything just covering everything up instead of using the motors to hold stuff together and better like real humanoids do. And many other things that i will make a video on. gen2 fluid teleoperation The second version was a huge improvement. Teleoperation was smooth, I had the software stack working well, and I was even able to experiment with reinforcement learning policies and software in depth. But mechanically, I knew it was still far from where it needed to be. Also Hardware. I had to add Robstride 04 and 03 to my actuators for required torque. For economic reasons i made the biggest mistake in my life that was selling the NVIDIA JETSON AGX ORIN. Anyways i got a JETSON ORIN NX 16GB as a replacement. So I scrapped that one too. (burning money yay) Now I'm building what I consider my latest iteration, and I'm continuously improving it before machining the final parts. My goal is for this robot to run, jump, and eventually do whatever I can teach it to do. I am heavily focusing on manipulation btw. This time the design process is completely different. I've incorporated finite element analysis (FEA) for every part, proper mechanical engineering principles, design for manufacturing (DFM), and many of the concepts used in modern commercial humanoid robots. Thanks ARXIV for many papers. https://preview.redd.it/34e3quus56dh1.jpg?width=851&format=pjpg&auto=webp&s=c2fc7eeae553f11ffae6176221c969f8e506de2f https://preview.redd.it/or3qjrno56dh1.jpg?width=881&format=pjpg&auto=webp&s=169be6140f54de577e7fb93c9adccef497d6e4f2 https://preview.redd.it/6ccn0qap56dh1.jpg?width=642&format=pjpg&auto=webp&s=1459308f1b2bf675cf6e4ee9df311b09175fd12f This was before i understood that a screen on a head of a robot that will be falling is not a really smart idea. Latest Iteration (WIP): https://preview.redd.it/znp4kfki56dh1.jpg?width=784&format=pjpg&auto=webp&s=ab0352498c8ef68ec840508d03b49831e0ffe669 https://preview.redd.it/lo12fc8k56dh1.jpg?width=1018&format=pjpg&auto=webp&s=90c0bc6451bdfca5c3cb8570700e03cf0bae0d0d STILL IMPROVING. and Yes this is not just a CAD Humanoid. I have burned around 20kg- 25kg of PETG,PA-CF and some aluminum parts trying to make it happen :) i will be posting new iteration teleoperation and manipulation videos soon. BTW One challenge I didn't expect was the battery. Lithium batteries are heavily restricted for import in my country Honduras, so I had to design and build my own DIY Li-ion (please do not use LIPO on humanoids that walk) battery pack from scratch. Which i have a full video on how to do it for a humanoid robot specific needs, i am sure this might help atleast someone. I've failed more times than I can count. But every failure taught me something. I'm going to keep building until this robot walks and eventually reaches the level of commercial humanoid robots. I AM HEAVILY FOCUSING ON MANIPULATION. And yes... It will be OPEN SOURCE. I'll continue posting updates here and on X, and I'm also working on a website where I'll publish in-depth tutorials explaining how humanoid robots work (FROM MY LEARNING) and how you can build one from scratch. Thanks to everyone who's been following the project. And also thanks to everyone that has made fun of me too! I have been building this totally alone. for 110 working days exactly. I have 110 days of videos of the process. With Honor, Carlos Abrahan Lopez :D https://x.com/carloslopeezr submitted by /u/Medical_Skill_1020 [link] [Kommentare]

Interesting engineering from MyActuator. What do you guys think? This a Dual encoder ACTUATOR. I believe its really expensive for what it is. submitted by /u/Medical_Skill_1020 [link] [Kommentare]

https://www.youtube.com/@ALMA.Industries This is a control interface for using AC and DC power in on place. Switches turn 3 different DC power supplies on and off (48v, 12v, 24v). AC Outlets always give power regardless of switch states. This is gonna be part of my next video, where this is mounted on a desk build. Full video goes through all stages of build. submitted by /u/ALMA_x11 [link] [Kommentare]

Hope to see you around here or YouTube :) submitted by /u/ALMA_x11 [link] [Kommentare]

I saw this robot at Seattle space needle and thought it was cool. A few people said some of the robots ask for a tip. I think it would be real cool if it had a towel and could clean up its own mess after making coffee. submitted by /u/mattsrobotics [link] [Kommentare]

newbie here -- i dont know a lot of things about robotics , trying to learn what aspects i like and what i don't ! I built an Android-based AI vision coprocessor that performs real-time object detection, tracking, and monocular distance estimation using custom TensorFlow Lite models trained on my own datasets. The architecture is modular, so supporting a new object only requires retraining and swapping the model and configuration—no changes to the application itself. It streams lightweight perception data to embedded controllers like the ESP32, with future applications including robotic manipulation, industrial inspection, and autonomous sorting systems such as fruit and vegetable grading. for now i have trained a model to track a highlighter pen i had XD also i have attached logs of what exactly it delivers to esp32 / arduino ( in .json ) device : old redmi 5a , 3gb ram and 20gb storage -- so yeah for now its a lot jittery and distance updates are not very smooth, trying to optimise it ! these are the logs i saved through terminal for demonstration purposes , but its pretty much whats recieved by esp32 -- these can then be used by actuators to work upon submitted by /u/_Jiggle-Physicist_ [link] [Kommentare]
