I recently came across a very affordable 8115 45kv (0.3ohms phase R) motor kit which includes a wound stator and a steel magnet ring . Quickly modeled a mockup in Fusion : https://preview.redd.it/ckbo2a7d5h7h1.jpg?width=1043&format=pjpg&auto=webp&s=40716922ce7ca2358503ede09badaa0f0de7417c https://preview.redd.it/rrtz8qvd5h7h1.jpg?width=1280&format=pjpg&auto=webp&s=9b356dfab5d5953781b3e0b4d9fcb25fb3f2a37c Instead of using a pressfitted central shaft like most bldc do , i opted for a pilot diameter directly on the rotor to locate it on the 52x40x7 bearing (possible stiffnest improvement ?) then use 2 bolts ,circular nuts, a plate to preload and lock the bearings and rotor to the stator. I'm also using a very shallow bearing seats with both 7mm thick bearings lightly-pressfitted in to shallow 3mm seats. Would this work or this housing design need to be scrapped immediately ?

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]

Hello, The problem looks simple at first, but it really isn't. Building a media stack that behaves the same whether it runs inside the robot, on your laptop, in simulation, on your phone, or on a distant powerful machine (all with short, repeatable delays) is anything but trivial!

With NVIDIA Jetson AGX Thor bringing a major jump in AI performance, I've been wondering whether the next bottleneck in embedded vision systems will no longer be compute—but camera architecture. In many real-world deployments, challenges often come from: Multi-camera synchronization Camera bandwidth Sensor interface limitations High-resolution video pipelines System latency Memory throughput As AI compute becomes less of a constraint, do you think future vision systems will be limited more by how cameras are connected and managed than by inference performance itself? For example: Will larger multi-camera systems become more common? Which interfaces are best positioned for next-generation systems: MIPI, GMSL, Ethernet, or something else? What challenges do you see when scaling vision systems for robotics, autonomous machines, or industrial automation? One interesting point I've been seeing is that discussions around AGX Thor are increasingly focused on sensor bandwidth, camera scalability, and system architecture rather than AI performance alone. Curious to hear how others see AGX Thor changing embedded vision system design over the next few years. For anyone interested, I recently came across a discussion on AGX Thor from a vision-system perspective that covers camera integration, multi-camera scalability, and future deployment considerations: 🎧 NVIDIA Jetson AGX Thor Vision Systems: Camera Integration and Deployment Considerations What do you think will be the biggest bottleneck in next-generation vision systems?

The robot behaved long enough for us to record this video. This robot was developed for the RoboMaster competition and powered by us. submitted by /u/Cubemars [link] [Kommentare]

I keep thinking about this idea of a small robot that lives on your desk and is built specifically to help you focus, not just look cute. Like, it tracks your work sessions, notices when you've been scrolling instead of working, reacts when you hit a deep focus streak, calls you out when you've been on your phone for an hour. Vector and Emo type robots failed because they were essentially toys pretending to be useful. What if you flip it? A focus tool with a personality, not a toy with productivity bolted on. Right now it's just a side project so I'm focused on getting the prototype right first. I will take it to cocreate pitch. Price range I'm imagining: somewhere between a fitness band and a smartwatch. submitted by /u/RemarkableCaptain318 [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.

Hey r/robotics, I’ve been playing around with bridging AI and simple, accessible hardware. The goal is to avoid buying expensive robotics gear, starting instead with a basic

I want to make a post asking for help. I want to buy a 3D printer to start printing some components and figures that I might be able to sell in the future. I mainly want to print robotic parts such as housings, arms, or support pieces that I could use for robotic kits. I want to know which is the best 3D printer to start with without breaking the bank. My budget is around 350–400€. I have some good experience using the Elegoo Neptune 3 Pro and the Raise3D Pro2 Plus, which I often use to make parts and components for my projects at school. I want to get something similar to the Elegoo. I was considering these 3 options: • Bambu Lab A2L • Elegoo Neptune 4 Plus • Elegoo Centauri Carbon I want something that isn’t too big but not too small either. I also talked to some teachers, and they told me to take into consideration that at some point I may need to repair or replace some parts of the printer, which could cost more or less depending on the model. So I want to keep that in mind too. If anyone can help me, please submitted by /u/Mf_KingIsHere [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]

Curious if this neck mechanism is realistic using what appears to be Nema 17 stepper motors.
