Am currently building a RC tank for a hobby project that wants to implement VSlam. Because of power constraints I want to use low power microcontrollers like esp32-cam and stream video to a laptop that then computes the navigation data. The idea being the ESP32 cam will upload IMU+stereo camera data -> Laptop computes current path and location -> Streams back navigation instructions. This doesnt have to be completely real time, as the robot can wait until a navigation solution is computed, execute the solution, stream back then wait for further instructions. My question is are there better ways to do something similar? Accuracy is the most important quality here. Or would a Lidar soluation be better? submitted by /u/FollowingHumble8983 [link] [Kommentare]
I'm 15 years old and this is my hexapod project I have been working on for the past year, I learned a ton from it. Here are its specs: -Build: Mostly 3D printed, I used a model from Aecert Robotics from youtube, I made some changes and improvements to the model such as the femur joints that connect to the servos. -Parts: 24 channel Pololu maestro board, 11.4v lipo battery, 12x25kg servos, and 6x35kg servos (for the femur joints because they're under the most load). Cheap android phone for the controller and gyroscope, and a DROK buck converter. -Software: I made a custom android app for the controller that connects via wifi or hotspot, you scan a QR code and it opens the controller on your phone. I used inverse kinematic equations for the hexapod so it has complete control over the leg and body movement. -Stabilizing: Using the gyroscope from the phone it can also self stabilize, it can even walk and self stabilize at the same time. -Walking gait: There are 5 walking gaits so far: Tripod, ripple, wave, triple, and a custom one I made to look like a spider. -I'm currently working on a high precision robot arm and I would love some feedback: About 4ft long and hopefully can lift around 5lb. I should have some videos soon. If you want to learn more about the hexapod or the arm you can see them at my portfolio. submitted by /u/Safe_Tone1529 [link] [Kommentare]
That's a drone in the picture! Computational design generated a spinning drone that’s nearly transparent. Called the phantom twist, it's still loud, but it's quite hard to see with a human eye.

I submitted my TACL paper approx on June 1th and was scheduled for July 1st cycle, when and how do you guys think we'll be getting our reviews given the July cycle for the paper which I've submitted at TACL ? And how long does the entire process take for those who have submitted to TACL ? Also, I do want to ask, how good is TACL as a journal and how respectable or how is a TACL publication viewed ? submitted by /u/Practical-Buddy6323 [link] [Kommentare]
Hi everyone, LinkForge recently crossed 5,000 downloads on the Blender Extensions platform, which was a nice milestone. The project started as a Blender extension for building robot models, but over time it has evolved into something a bit different: a programmable Intermediate Representation (IR) for robot descriptions. My goal isn't to replace URDF or XACRO. Instead, I see them as compilation targets, while the IR becomes the editable source model that can be validated before export. The core is written as a standalone Python engine, so it can run in Blender, from the CLI, or in automated pipelines. I'm curious what others think: Do you think robotics is missing a proper intermediate representation between CAD/design tools and formats like URDF or MJCF, or do existing workflows already solve this well? I'd genuinely appreciate feedback from people building robots professionally.

I have been working on this project over the past 6 months. Its a 3d printed hexapod robot dog, I call it HexaDog ZBD (English Pronunciation of ZBD means raggedy in Turkish). I used ESP32 S3 for its brains, 2x PCA9586 boards for servo connections, 18x DS3218 servos, 1x IMU, 3x 15a 300W buck converters and almost 2kg of PLA. Total robot weight is about 2.7KGs with 3s2p 18650 batteries (some sparks were created during the earlier design of the battery case) I have been testing it indoors and outdoors I am quite happy and surprised for the amount of work I got out of ESP32. I plan to convert the gait mechanism from Inverse Kinematics to a small neural network through imitation learning and run it on ESP32 as well if one core can handle the neural network while the other handles the WiFi access point and screen updates it will be golden! I have done the neural network generation from IK and controlled the robot with it in Pybullet now I have to try it on real robot. Total BoM was a close to 400 USD in Turkey (Import Taxes), but I checked on Ali and if you source them form China you can lower the costs down to about 200 USD. Amazon US prices are close to 300 USD. I plan to open source all desing files, scripts and android controller app APK. I am currently cleaning all my design files and scripts and organizing them so once I upload them there are no bugs. I wanted to get community opinion on it to see if anyone would also be interested in building one. If you wish to test it out in simulation before attempting to build one, the github repo link below contains a Pybullet demo of the robot. You can download it and control it in an empty Pybullet environment and check out the simulation script for yourself. https://github.com/serdarselimys/HexaDogZBD-PybulletDemo Let me know what you think, I wanted it to be an affordable and simple modular platform for anyone interested in robotics to experiment with it. submitted by /u/Xerd-R [link] [Kommentare]
Hi folks, I am kind of new to fine tuning a model. I don't know how to fine tune. Now our team have to fine tune a model on one project. What we decided is, we will be using small model like, llama, mistral, or Gemma, and them feed it with our data. And from there we will be train our model. But this is just a talk we had. None of us know how to fine tune a model. So can you guys, take some effort to help me like how should I do it? How to initiate it? The roadmap I can follow to fine tune it. Would really appreciate your response. submitted by /u/EngineerCtrlT [link] [Kommentare]
Lately in the last two/three years, I have noticed ICML, Neurips becoming more prestigious than the actual journals. What is the actual reason of this culture? Is this due to the AI boom and rising demand and the fact that conferences have a higher and a faster acceptance rate as compared to journals and with the growing hype they need to deliver things faster? What do you all think? submitted by /u/hg_wallstreetbets [link] [Kommentare]
MIT professor Yoel Fink talks about why tech companies often end up building similar products. He points to glasses, headsets and watches as examples of companies moving in the same direction. His argument is that this kind of pattern can cause teams to miss other paths. For smart fabrics, Fink says the starting point should be the fact that humans already wear fibers every day. Clothing is already accepted on the body in a way that metal, glass and rigid devices are not. That makes fibers a practical place to explore sensors, computing and human-machine interfaces. submitted by /u/Responsible-Grass452 [link] [Kommentare]
I understand that it may not be appropriate to call it “officially accepted” yet because of the wording used in the notification, and I also saw on Twitter/X that they said they are working on it. However, it has already been around three weeks since then, and we have already submitted the camera-ready version. Registration, visa applications, travel planning, and funding requests all depend on this confirmation. For some people, it is difficult or even impossible to request funding without an official acceptance letter or clear confirmation. I really hope the organizers can handle this more professionally and be more considerate of authors who need proper documentation for administrative purposes. submitted by /u/National-Resident244 [link] [Kommentare]
After designing and printing the gearbox in-house, it’s time to see how much torque it can actually handle. Early results look promising — more testing and improvements coming soon! submitted by /u/Personal-Wear1442 [link] [Kommentare]
Well, every post i see in this sub is about how robot almost killed someone.. So what could you guys said about soft robotics? Does market need it? Does engineers want it? Maybe someone even know current progress in this field? submitted by /u/Fabulous_Diamond_381 [link] [Kommentare]
