Hey Community, Back in January I was visiting Shenzen and I saw these camera robots that follow skater and film . A few days a go I saw these camera robots BENI robot but since it’s not open platform it’s not an option for me . I was searching around for follow bots in china but did not find a lot :( Anyone here who knows wich one this is ? submitted by /u/Spinning-Complex [link] [Kommentare]

I'm considering building the Toolbox Robotics EB15 or EB300 3D-printed robotic arm and would love to hear from people who have actually built one. ​ I'm particularly interested in: ​ - Overall build experience, assembly difficulty, and total filament usage. - Motion performance: Is the arm smooth or jerky? How much backlash, vibration, or missed steps do you experience? - Real-world performance: accuracy, repeatability, payload, and long-term reliability. - Software experience (ROS, MoveIt, control software, etc.) and any modifications or upgrades you would recommend. ​ Photos, videos, build logs, or GitHub repositories would be greatly appreciated. ​ Links:- ​ https://toolboxrobotics.com/robotic-arm-eb15 ​ https://toolboxrobotics.com/robotic-arm-eb300 submitted by /u/Fals3_ [link] [Kommentare]

​ Hello I'm currently 26 I have 3 years of experience doing general IT help desk work and web development. I want to move on to having a deeper understanding of things and securing them. I have a undergrad in IT. I want to work with security but not only apps and networks yes this interests me but I'm also interested in the system or device itself how that's secured. Alternatively I am also interested in how a computer works, how to solve real problems with it, how a computer processes and sends data physically and then through a network and how to build computers themselves and as well as computers in bigger devices like robotics and how build bigger systems like a robotic arm. So I'm a little confused on if I should do my masters in computer engineering and add on cybersecurity electives or should I do computer science and on hardware or embedded systems electives. I do have the option at my school of double majoring as well but I think that would be to much work especially because if I do CE i have a big foundation to cover. ​ ​ ​ https://catalog.uhcl.edu/preview\\\_program.php?catoid=25&poid=7072 ​ ​ ​ https://catalog.uhcl.edu/preview\\\_program.php?catoid=25&poid=7074 submitted by /u/Colfuzi0 [link] [Kommentare]

The first build video for the Autonomously Exploring Viam Rover is up! This one is showing how to set up the Radxa X4 before putting it into the robot kit. There will be more videos in the playlist, so stay tuned if you want to build your own version! https://youtu.be/v7vi2d8ITEQ submitted by /u/mikelikesrobots [link] [Kommentare]

When working on robot models, I often wanted to: Open a shared link See the robot instantly Inspect joints and meshes Validate URDF errors Export to other formats That's why I started building RoboInfra. You can paste URDF/Xacro and instantly get: 1) 3D visualization 2) Validation 3) Auto-fix suggestions 4) URDF → MJCF conversion 5) URDF → USD conversion 6) Shareable robot links 7) And much more What other features would you expect from a tool like this?

I have developed an articulated rigid-body dynamics framework in C++23. The project is a compact, light-weight implementation of Featherstone's spatial algebra, (plus ABA/CRBA/RNEA dynamics), URDF import/export, collision detection, contact handling, and end-to-end automatic differentiation. I’m currently working on a Vulkan-based visualisation application (see demonstration videos). I would be interested in feedback from the ROS and robotics community, particularly regarding project architectural choices and possible future research directions.

A few questions: Has anyone here used them before? If you know, how widely are they adopted in research and or industry? If you have worked with or is currently working with them, what kind of interface are you using? As for me, I'm currently using their X, AX, and MX series to build an autonomous mobile hexapedal manipulator robot for academic research and I'm interfacing them through an STM32 microcontroller running a bare-metal half-duplex UART driver for the servomotor I wrote myself. My specific application which requires an onboard and flexible microcontroller driver makes working with the official controller firmware rather tedious or unnatural, so that's why I wrote the driver from scratch per-protocol. Because of the problem, I'm interested on making my bare-metal driver portable by parameterizing the transport layer around per-protocol packet handler and builder code before eventually releasing them to the community under an open-source license. Do you think it's a worthwhile project? submitted by /u/Nusto1n1 [link] [Kommentare]

This is a self-balancing robot built around an ESP32. It uses two NEMA 17 stepper motors driven by DRV8825 drivers and an MPU6050 IMU. The biggest challenge was tuning the PID controller and filtering the IMU data for long-term stability. After a lot of tuning, it can now balance continuously—I even recorded it balancing for 45 minutes straight without falling. submitted by /u/mAbdelazim01 [link] [Kommentare]

Curious, how many of you use solutions to remotely view what your robot is seeing, or in some scenarios even remotely monitoring/configuring your entire inference stack? This is my attempt of what that looks like. I am happy to provide early access for the community! submitted by /u/Logical-Present6320 [link] [Kommentare]
