Hi r/robotics ! I’m currently working on a robotic car project for mapping, and I’d like to share my progress and get some feedback from the community. So far, the main issues I’ve encountered (and resolved) are as follows: - Synchronizing the car’s position on the map (as indicated by the gyroscope) with the position of the digitized image based on the car’s position - Managing the motors’ power supply (complex wiring) However, there are still a few issues for which I could use some advice. - It seems that over time, a discrepancy is developing between the robot’s position on the map and its actual position as measured by the gyroscope. Is this an inaccuracy in the gyroscope that could be corrected through code? - The scanner works but remains fairly inaccurate; any recommendations are welcome - The robot’s path tends to veer off course, so I’m considering adding speed encoders to implement a path correction system (I assume the problem stems from the fact that the speed of each motor isn’t always precise) My goal is to build a fully autonomous car capable of mapping its surroundings (I'll add a webcam). Feel free to share any ideas you might have. my target is build a full self driving car able to mapping his environment ( i will adding webcam).

Hey everybody! Hobbyist here with an update on my cheap rover swarm project. I've been trying out Depth Anything 3 and wanted to share, because the results of such minimal hardware surprised me. The setup: each rover is just a XIAO ESP32-S3 Sense (~$15 board with a tiny onboard camera) in a 3D printed body. The ESP32 is basically a sender, it streams the camera over WiFi and reports temperature/battery/telemetry. All the heavy lifting (DA3 inference, navigation) runs on a PC that acts as the brain. No lidar, no depth sensor, one cheap RGB camera. DA3 gives me a point cloud per frame and can merge multiple frames into a larger cloud. Seeing a $15 camera produce a usable 3D-ish image of the room is still kind of wild to me. Eventually I want to use it for navigation - a kind of "poor man's lidar". It estimates what's near at three heights (eye level, above, below) to give a rough obstacle sense without a dedicated sensor. Secondly for visualization at the moment, but the goal is to stitch frames into an environment map. Positioning is currently handled by ArUco markers around the room (solvePnP). Still early and held together with hope, but it's been fun pushing this hardware further than it wamts to go. :-) submitted by /u/monkeydance26 [link] [Kommentare]

HalfwiredTV is a community for people who want to learn robotics, build projects, and collaborate with others. Our long-term goal is simple: Get everyone to a level where they can confidently learn, build and collaborate on robotics projects together in livestreams. What You'll Find Here -- People learning together teaching each other on calls in dedicated channels for topics (created as per demand) Project teammates Livestream collaborations and study sessions (uhm.. with meme songs) , also whenever anyone has something interesting to talk and show regardless of their skill level. We recently had our first livestream on a member's lazer scanning workflow for their robocar Robotics discussions ranging from complete beginners to advanced builders Your skill level doesn't matter. If you're curious, willing to learn, and willing to build, you're in the right place.

Hey everyone, I've been talking to a lot of robot engineers and kept hearing the same frustrations: - Debugging ROS2 errors takes hours - Setting up proper logging is painful - Writing boilerplate nodes wastes expert time So I built **Mechis** — a free AI co-pilot specifically for robot engineers. **What it does:** - 🐛 **Debug** — paste your error or stack trace, get the exact fix - 📋 **Logging** — describe your robot setup, get a complete ROS2 logging config - ⚙️ **Code Gen** — describe what you want in plain English, get clean ROS2 Python code **Try it free here:*\* mechis-neon.vercel.app No signup needed. Just open and use. --- **I'd genuinely love your feedback:** Did it actually help or was the answer generic? What's missing that you wish it had? What's the #1 ROS2 problem you face daily that a tool like this should solve? Would you pay for this? submitted by /u/According_Koala4857 [link] [Kommentare]

Officially i have finished the design, from now i will be working on the electrical components and control. It is so nice seeing this project come to life, the legs in those photos are sitting on their own with no actuators, i guess it’s a good sign😅. Now the big question remains, if i can make it walk🤷‍♂️ submitted by /u/DIYmrbuilder [link] [Kommentare]

Andrew Barry from Generalist says the company is upfront with people collecting robot training data: the data is being used to train robots. Some workers are excited by that, especially when the tasks are repetitive, physically demanding, or jobs they do not want to keep doing.

Curious if this neck mechanism is realistic using what appears to be Nema 17 stepper motors. From an animated series online (Elberr). https://preview.redd.it/n67mm00oz87h1.png?width=1640&format=png&auto=webp&s=2ab62ce3046d173cb88432848e2150767405d6ce https://preview.redd.it/z39nq50oz87h1.png?width=1640&format=png&auto=webp&s=ea70615ede462bab141915d7f93e7d14e90cfd79 submitted by /u/Positive_Valuable980 [link] [Kommentare]

I'm making a custom bldc motor to use as the main propulsion for an automated rigg to map the bottom of the sea! For now i'm testing it in my paddle surf, outside the water it seems to be way to powerful! The motor itself is all 3d printed, I'll soon make a post about it! submitted by /u/ArnauAguilar [link] [Kommentare]

What if Playmobil figures were scaled up and equipped with AI, turning them into physical AI companions? It could be fun if their hands kept the classic C shape design but were upgraded with 3or 4 degrees of articulation, allowing them to perform simple tasks. (such as fetching a pen, making tea or coffee, and other basic household activities) The face could be a display screen. When powered off, it would show the classic Playmobil eyes and smile. Once activated, it would come to life with expressive eyes and facial animations similar to the characters in , allowing it to move and interact more naturally. What do you think? submitted by /u/Difficult-Limit-7551 [link] [Kommentare]

Hey everyone, ​ I just completed my first year in Electronics and Computer Engineering and I’m currently working on a robotic arm project. ​ I already have the STEP files, datasheets, and most of the components finalized. The issue I’m facing is with the actual mechanical CAD/design part in Fusion 360 — mainly assembling the arm properly, joint design, motor mounting, bearing placement, alignment, etc. ​ I’ve tried using AI tools like ChatGPT and Claude for guidance, but for complex robotics CAD they often give incorrect Fusion 360 steps or impractical mechanical solutions. ​ I’m looking for someone who has experience with: ​ - robotic arm design - mechanical CAD - Fusion 360 - robotics assemblies ​ Even some guidance, feedback, or help with a few parts of the design would really help me move forward. ​ I can share a ZIP file containing all the STEP files and datasheets if anyone is interested. ​ Unfortunately I can’t pay right now since I’m still a student, but I’m genuinely trying to learn and build this project seriously. ​ You can DM me or contact me at: deepkukreja31@gmail.com submitted by /u/Life_Transition3270 [link] [Kommentare]

I have been planning this for a while now. It's basically a youtube live stream where we learn robotics concepts together, ask each other doubts, discuss, make weird robots, some shinaneigens and most importantly just have fun. You can choose to not show your face, or vtube like me. Right now I have started learning the physics behind robotics using a book called Modern robotics by Kevin lynch and Frank Park. You can either learn it with me(I have only seen a couple of pages, I can teach you in like 20 min to get you to where I am) or if you want you can choose to just do your own thing simultaneously as well. Any suggestions or feedback to get as many people as we can is appreciated 👍 I really want to make the robotics community to become friendly and fun . Just dm me . we'll plan exactly how to undertake this (let's say a discord call in the stream or chat based etc.) submitted by /u/SundeepKuPanigrahi [link] [Kommentare]
