Hey r/robotics, A while back I posted asking for name suggestions for my new mobile robot platform. Last time around, you guys gave me Arctos for the 6-DOF arm. This time, the top upvoted comment was Cary McCarface. So, officially, the robot is designated Arctos CMC. The "CMC" stands exactly for what you think it does. I finally finished the full build and just put together a quick video showing it driving around and doing its thing. Despite the ridiculous name, a lot of engineering went into making this thing work on a budget. If anyone wants to build one of these themselves, I’ve made the CAD files available. I’m also working on putting together a hardware kit that will be coming soon, but until that's ready, the full Bill of Materials (BOM) is available so you can source the parts yourself. submitted by /u/ganacbicnio [link] [Kommentare]

Hi reddit, I've built an accessibility app that helps people with mobility issues play video games hand-free and now we're developing a human-robot interaction for robotic systems. This HRI can help teleoperation of robots by providing a more precise and faster input method by using person's head movements to guide mechanical actuators, robotic arms etc. in combination with regular controllers. We are looking for a use-case provider with the profile of industrial company or infrastructure owner providing the industrial testbed, defining the use case for inspection and maintenance. And would like to join us in the JARVIS open call 2: external pilots stream. Any advice on finding someone for such a project is also VERY APPRECIATED. We are new to robotics industry and would love to make it happen as this HRI can also help a lot of people with mobility issues to control things in their day to day lives, like wheelchair robot arms or assistive robots. If you know anyone we could reach out to, please don't hesitate to DM me or comment. Thanks! submitted by /u/SensePilot [link] [Kommentare]

This video demonstrates how AI Sapiens learns and performs full-body humanoid motions in just one week using NVIDIA technologies. Powered by NVIDIA Jetson Orin™ NX, NVIDIA Isaac Sim™, SOMA Retargeter, and NVIDIA Kimodo, AI Sapiens performs walking, running, balancing, and various full-body motions through simulation, motion retargeting, and reinforcement learning. https://docs.robotis.com/docs/systems/aisapiens/introduction/ submitted by /u/drgoldenpants [link] [Kommentare]

Officially i have finished the design, from now i will be working on the electrical components and control. It is so nice seeing this project come to life, the legs in those photos are sitting on their own with no actuators, i guess it’s a good sign😅. Now the big question remains, if i can make it walk🤷‍♂️ submitted by /u/DIYmrbuilder [link] [Kommentare]

I wanted to see how far AI could actually help with CAM programming, so I ran an experiment. I gave Claude AI a humanoid robot knee joint and asked it to generate the machining strategy for Fusion 360. Then I took those recommendations, built the CAM setup, and machined the actual aluminum part. The result surprised me. It wasn't perfect, and I definitely wouldn't run AI-generated toolpaths without reviewing them, but it got much closer than I expected. A few things I'm curious about: Where do you think AI helps most: setup planning, tool selection, workholding, feeds/speeds, or actual toolpaths? What would it need to do before you'd trust it on your machine? Video here if anyone is interested: https://www.youtube.com/watch?v=L1HeTR-Eawg For context, this part is for an asimov open-source humanoid robot I'm building in my garage. submitted by /u/e-mando [link] [Kommentare]

I’m aiming to optimize the ratio of (push force)/(actuator diameter), while also minimizing total diameter. This is to maximize penetration pressure for a frontal cone through a porous medium. The best I could find so far are the bullet series from firgelliauto.com. Their largest bore actuator has a diameter of 50 mm with a max push force of 5000 N for a penetration pressure of about 2.55 MPa. 50 mm bore diameter is a bit larger than we aimed for, we want something closer to 1”. Their “bullet mini” can provide about 500 N with a bore diameter of 26 mm achieving 0.94 MPa. Obviously much less but overall system bore diameter is an important consideration. Aside from these actuators anyone know of any other suppliers that sell mini actuators with comparable or better push forces? Mainly looking for off the shelf systems. Pneumatics and hydraulics cannot be considered. submitted by /u/quietbunny99554 [link] [Kommentare]

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]
