Update since: https://www.reddit.com/r/ROS/comments/1ugw66z/cubic_doggo_update_returning_to_basics_after_all/ Hello hello, I made some mechanical updates to Cubic Doggo 06R, just for it to lift its feet while walking. The black padding is measured to be around 4 mm thick. I really thought this would be simpler than the IMU, but with all the changes, this is as good as it can get. The servo load (3rd on for the feet joint) easily reaches 70%, so I have a feeling this is the best it can do. I hesitate to make the body's 3D-printed frame lighter because that can make it less sturdy, and most of the weight is from the servo and batteries (yeah, also, I get a bit lazy just thinking about all those bolts and screws). Any more suggestions would be great! Changes made are m The next step is to walk with IMU, and then finally going to do some simulation and RL.

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]

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.

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]

We've been building Sowbot (aka the Feldfreund devkit), an open-source ROS 2 Jazzy stack for small-scale agricultural robotics: RTK-GNSS localisation (dual F9P moving base), LCAS topological navigation on top of Nav2, and a NiceGUI web cockpit for mission planning — draw the field corners, it generates row coverage via Fields2Cover. Just got multi-row mission following working end-to-end in Gazebo: the robot sequences entry/exit points across a full field of rows on its own, no manual nudge between rows. Video: https://www.youtube.com/watch?v=A0CVNcp19vU Just simulation for now, not a field result. It moves navigation and the sim step forward on our roadmap — hardware field validation is next, and we're not claiming a finished product. Stack, if useful to anyone: Two-SBC split — Limbic (ESP32 firmware, sensor fusion, localisation) and Neo (perception) ESP32 running https://lizard.dev/ Containerised via Docker, full build/sim modes Fields2Cover for coverage planning Visual crop-row following (ExG + Otsu threshold) as a Nav2 action server for in-row traversal Stock Nav2 (Regulated Pure Pursuit) for headland turns between rows Built on Zauberzeug's Field Friend as a base, developed with Agroecology Lab (UK) and caatingarobotics (Brazil) Apsitech (India) navigation stack from LCAS's Agri-OpenCore ecosystem. Fully open source. Repo: https://github.com/Agroecology-Lab/feldfreund_devkit_ros WIP Reference hardware: https://sowbot.co.uk Happy to answer questions on the nav stack, sim setup, or anything else. PRs or collaboration welcome if this is your area. submitted by /u/Sabrees [link] [Kommentare]

Hey guys. A couple months back I asked this sub for some reality checks on using a 30:1 metal cycloidal to replace 3D printed joints for QDD. The first batch of CNC parts finally showed up. I was honestly expecting the tight machining tolerances to make it bind up, but turning the output flange by hand... the back-drivability is wild. Just for context: we were getting super annoyed with stripping the 3D-printed plastic gears on open-source rigs like the Berkeley Lite and ALOHA. They are awesome projects, but the plastic joints are fragile and a nightmare to maintain. So we designed this as a drop-in replacement (calling it the Starfruit Actuator). Instead of printing two different plastic joint types, we wanted a single unified metal design to simplify the BOM and actually survive dynamic loads. Specs we're rolling with for the final drop: 30:1 ratio (30 teeth, 31 pins) Dual absolute encoders (supports FOC & MIT modes) Fully ODrive-compatible Target price: ~$149 Next up is integrating the motor and driver board, then throwing it on the test bench to see if it survives a 76 Nm torque test without exploding. Fingers crossed lol. Let me know what you think of the machining! All the STEP files, ROS2 nodes, and configs are going to be 100% open source. I'll drop the project link in the comments if anyone wants to track the testing or grab the files when they go live. submitted by /u/External_Wasabi9131 [link] [Kommentare]

Hey everyone, I'm looking for a few people who enjoy robotics and might be interested in collaborating on an open-source robot project. I'm mainly looking for help with things like: PCB design 3D printable chassis Firmware/code Electronics planning I'll be sourcing the parts and assembling it myself. The goal is to create a low-cost robot that anyone can build and improve. This isn't a paid project, just something for fun and to learn together. If you've been wanting to work on a community robotics project or have ideas you'd like to contribute, I'd love to hear from you. Feel free to comment or send me a DM if you're interested. submitted by /u/Worried-You-7003 [link] [Kommentare]

Would a ASL-ML from BO3 work in real life as a Autonomous Quadruped Robot. I kinda think it could only problem would be power/batteries. If it would work what could it be used for? I mainly think security, patrolling important assets etc. submitted by /u/LowAcanthocephala528 [link] [Kommentare]

In this python simulation: a robot spins a sensor and receives the distance. I made the distance more inaccurate the farther it is from a wall. The white lines are the actual walls The green dots are the raw, inaccurate data points the blue lines are my attempt at trying to interpret the data points into walls The algorithm works like this: For every green dot, if there are two close dots, it finds the best fit line, deletes the middle dot, and moves the other two onto the best fit line. This averages out the slopes between the green dots to allow for slope comparison. For every green dot, if the angle of the lines connected the green dot in front and behind are similar, then they are clipped into just two dots (similar to the first filter). However, as you can see, it is making walls even farther off from the green points, especially for vertical sections. I suspect this is because I'm using y=mx+b, and the slope for a vertical line is undefined, so I think the algorithm has a hard time approaching that. For context, I'm an incoming freshman trying to design an algorithm for a roomba without any prior knowledge on SLAM algorithms, so I would greatly appreciate any resources for a better implementation or just general feedback. submitted by /u/ExerciseCrafty1412 [link] [Kommentare]

Hello guys, I’m a 3rd year mechanical engineering student (21 yo). I’m planning to start a YouTube Channel which I’ll do online interviews with engineers working in Aerospace and Robotics Industry about their specialization and their experiences. Are there any of you would be interested in to be my guest? submitted by /u/bertgolds [link] [Kommentare]

Implementing beam-search based algorithms for decision making turns out to be quite helpful for agents. Check the repo. submitted by /u/ahmedzeer [link] [Kommentare]
