[Explainer] What Is Model Predictive Control? Why Robots Execute Only the First Move

Quadruped robot predicting future poses while committing to the first platform

Model predictive control forecasts a robot’s short-term motion, optimizes actions under explicit constraints, executes only the first input and then solves again. This explainer uses legged locomotion to show the principle—and the limits imposed by model error, computation deadlines and safety requirements.

[Explainer] What Is a World Model? How Robots Imagine the Future Before Acting

Robot comparing several predicted futures before acting

A robot world model predicts how the environment may change under candidate actions, helping with planning, evaluation and training. This explainer covers action-conditioned prediction, real robot examples and why visually plausible futures still require closed-loop validation and independent safety controls.
