Building and Testing Robot Policies with MuJoCo
10+ min ago (267+ words) MuJoCo has become one of the go-to physics simulators for robot learning — it's fast, accurate for contact-rich manipulation, and has first-class Python bindings via mujoco and dm_control. This tutorial walks through setting up a robot environment in MuJoCo, wiring it up…...
Sim-to-Real Transfer for Physical AI Robots
10+ min ago (291+ words) A policy that hits 95% success in simulation and 20% on the real robot is one of the most common — and most frustrating — outcomes in robot learning. The gap between simulated and real-world dynamics, sensing, and visuals is called the sim-to-real gap,…...
Using VR Controllers for Robot Teleoperation
11+ min ago (409+ words) VR controllers (Meta Quest, HTC Vive, Valve Index, etc.) have become a popular input device for robot teleoperation, and for good reason: they provide precise 6-DOF tracking, built-in buttons/triggers for gripper control, and an intuitive mapping between human hand…...
Creating a Robot Sensor Data Recording and Replay System
10+ min ago (292+ words) Every robot learning project eventually needs the same infrastructure: a way to record everything the robot sees and does, and a way to play it back later — for debugging, dataset inspection, offline evaluation, or regenerating labels without touching the physical…...
Domain Randomization for Robust Robot Learning
10+ min ago (191+ words) Domain randomization is the idea that, instead of trying to perfectly match simulation to reality, you randomize simulation parameters widely enough that reality just looks like "one more variation" the policy has already seen. It's one of the highest-leverage techniques…...
omen-alpha vs GLM-5.3-Flash - AI Model Comparison
6+ hour, 2+ min ago (14+ words) OpenCode Related comparisons. Other model pairs to check....
Building an Imitation Learning Pipeline for Robotic Manipulation
14+ min ago (259+ words) You've collected demonstrations — now it's time to turn them into a working policy. This tutorial walks through building an end-to-end imitation learning pipeline: dataset loading, model architecture, training loop, and evaluation, using the demonstration format from the previous tutorial. Wrap…...
Understanding Neural Networks and The Core Idea Behind Them
24+ min ago (595+ words) Introduction Neural networks work by building a system inspired by the human brain that... Tagged with datascience....
