Mini 6 dof Arm. 3D printed planetary gearboxs &... more… [📍GitHub link below ] A mini 6-axis arm driven by stepper motors with custom 3D printed split ring planetary gearboxs and an inverted belt differential wrist with custom bearings, driven by low-cost stepper motors and TMC5150 drivers. Custom firmware was written in C for the STM32 MCU on an BTT Octopus board, to allow for full closed loop PID control using AS5048a encoders daisy-chained over SPI. The controller takes joint targets and returns joint states to a Raspberry Pi 5 streamed over CAN bus. All credit to James Gullberg: 📍GitHub: —— Weekly robotics and AI insights.

you pay it in reliability/strength but a thing i... really love about low-cost 3d-printed hardware is how it can be so harmless by design (plastic made with low-cost motors). kids can just play and experiment with it without risks/supervision and that’s such an amazing way to learnshow more

Hardware Production 🤝 Robotics But these motors... are CRAZY... synced: CNC motor synchronization helps make sure that different motors in a machine work together smoothly so that the machine can cut and shape materials with perfect accuracy. This is really important for making sure the machine does its job correctly. ✅ Helps the machine's parts move together perfectly, reducing mistakes and making things more accurate. ✅ Prevents the machine from getting damaged by keeping everything aligned. ✅ Allows the machine to work faster by making sure the motors are in sync. Synchronized CNC motors make sure machines work better, last longer, and create more precise products. —- Weekly robotics and AI insights. Subscribe free:show more

.Xynova is one of the top rising players in... China’s dexterous hand and humanoid robot components space, based in Hangzhou • They develop not only the hands but also all core components (linear actuators, motors, etc) and algorithms fully in-house • They use a hybrid drive system, combining tendon-driven and direct-drive methods • One of the most exciting features is wrist control and finger abduction/adduction, delivering much more natural hand and arm dexterity • They prevent the hand from overheating by placing one of the actuators in the arm (below the palm) • Hands are equipped with tactile sensors and lidars, with 23 DoF (human hands have ~27 DoF) The overall design is deeply inspired by real human hand and arm muscle movements, impressive biomimicry approach The Humanoid Hub and I interviewed their tech lead so stay tuned for more technical details!show more

Early results from my AI training runs. I've trained... my $200 robot arm on a simple picking task using imitation learning. It has learned to control the robot arm using only camera images and joint states.show more

You can create split-stack videos like this in one... click with the link below.👇 In the simple version, all you have to do is upload an image and it handles everything for you. But if you want more control, you can jump into graph mode and tweak each parameter to get more detailed, custom results.show more

As someone coming from gamedev, something as simple as... planning and executing motion on the arm to this day gives me a feeling of wonder. It’s essentially just an IK solver from which the joint angles are computed and then applied to the motors. Nothing new. But it moves physically! (robotics people may now laugh at me haha)show more

I had an early access to GPT-6 Astra and... I can say, everyone in the world now has a 3D designer at their fingertips.

hi all, excited to join! i'm building an expressive... mini "shoggoth" robot which will eventually be hooked up to gpt4o realtime voice. i'm currently working on the low-level policies, which are trained in a mujoco simulation with RL. to delay working on raw-pixels for now, i trained a pose-estimation model using deeplabcut and triangulate the position in 3d space using the stereo cameras. eventually, i'll use gpt4o's tool calling capabilities to activate several of these policies (closed and open loop) based on the dialog flow! captions: manual actuation of the tentacle / 3d pose estimation / target designshow more
