I'm on my semester break and using the time to learn robotics. I just got my wheeled robot running in Gazebo!! what should I explore or build next? Looking for ideas, challenges, or a roadmap. submitted by /u/AxBodiSpray [link] [Kommentare]
I had a first go, putting together some of our friends in the space + a bit of research. Who’s missing? Feel free to tag your venture in the comments. submitted by /u/Erlapso [link] [Kommentare]
Stress testing my homemade 6dof arm! Total BOM of about $200, uses 4x STS3250 servos (50kg torque) and 3x STS3215 servos (30kg torque). submitted by /u/earthtojek [link] [Kommentare]
I’m working with a dataset inventory of around 500K hours, including egocentric and real-world robot-training footage. I’m curious what formats robotics teams currently need most—manipulation, household tasks, teleoperation, or something else? Comment below or PM me if you’d like to see samples. submitted by /u/WideAmbition1964 [link] [Kommentare]
How do you handle optical-flow dropout in GPS-denied tunnels? Been poking at navigation for tight indoor/underground spaces (tunnels, under bridges) where GPS just drops and there's nothing to fall back on. The annoying part is optical flow basically dies in there: bare concrete, repeating geometry, almost nothing to lock onto. Ends up being mostly lidar plus an illuminated camera doing the work. Testing it in sim first for obvious reasons (not keen on flying real hardware into a concrete wall to find the failure modes). Running it on UE5 with PX4/ArduPilot in the loop. For those who've flown GPS-denied in feature-poor spaces: do you just lean harder on lidar, or is there a VIO setup that actually holds up when the visual texture is that poor? Curious what's worked. submitted by /u/AlexThunderRex [link] [Kommentare]
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]
Aya Durbin says humanoid robots need to prove real customer value before they can scale. She says the goal for Atlas is not just to be impressive, but to deliver positive ROI for customers. Boston Dynamics is focusing on industrial environments first, especially work that is hard to hire for, physically demanding and difficult to automate with traditional systems. She also says customers need robots that are reliable, useful and able to become a trusted part of the workforce. submitted by /u/Responsible-Grass452 [link] [Kommentare]
This article looks at some of the common sensor integration challenges in motion control, including signal compatibility, communication protocols, environmental noise, and the growing demand for smarter feedback systems. As robots, AMRs, machine vision systems, and motion control platforms get more advanced, the challenge is not just adding more sensors. It is making sure the data is usable, synchronized, reliable, and actually helps the system make better decisions. As submitted by /u/Responsible-Grass452 [link] [Kommentare]
Hi all, just wanted to share a small project I built over a few robotics series. This one builds on top of the mycobot 280pi that I won from a competition, thought it was a fun project to learn with MoveIt2. The raspi itself ran extremely slow, so I had to find an alternative to control from another PC to run the MoveIt and Computer Vision applications via TCP. Feel free to check it out. submitted by /u/OkThought8642 [link] [Kommentare]
Should I buy a 3D printer to print it? Will I likely make use of the printer again for desiging other parts or something? submitted by /u/boringblobking [link] [Kommentare]
I put together a small ROS 2 subsystem that turns a 2-DOF pan/tilt platform and a cheap 2D LiDAR into a stop-and-capture 3D scanner, and figured it might be useful to someone else here. The setup: two Feetech STS3215 serial-bus servos aim an LDROBOT LD19. A node sweeps the platform and an assembler stacks the 2D scans into a `PointCloud2` using the live TF tree. There's an optional MQTT bridge so an external controller (in my case a microcontroller mission queue on a rover) can trigger scans and get a completion handshake back. It's a *complete* project — it even includes a fix to the LiDAR driver (upstream `ldlidar_stl_ros2` won't build on recent GCC/glibc; the patched fork is linked below). It talks to the rover over a well-defined set of MQTT messages, but every command also has an equivalent ROS 2 topic, so if you want a pure ROS 2 setup you just don't launch the bridge. (Personally I love the MQTT side — it lets me drive the whole thing from a tablet.) No vendor SDK — the Feetech STS/SMS half-duplex protocol is implemented directly over pyserial, including handling the URT-1 adapter's habit of echoing every TX byte back on the RX line (the kind of thing that eats an evening if you don't know it's coming). The assembler is driver-agnostic: it consumes standard `sensor_msgs/LaserScan` on `/scan`, so any conformant 2D LiDAR should work. It's running on an RK3588 today and is built to go headless on a Pi 5. This is the first piece I'm open-sourcing from a larger autonomous rover project, GPL-3.0. I'd genuinely welcome feedback — particularly from anyone who's done multi-LiDAR or TF-timing work, since the scan-to-TF synchronization was the fussiest part to get right. But it does work! Happy to answer questions about any of it.
