# Course 1: Model-in-the-Loop (MIL) for Robotics
**Level:** Beginner to Intermediate
**Duration:** 4-6 weeks (20-30 hours)
**Prerequisites:**
* Basic robotics concepts
* Basic control systems
* Elementary C++ or Python
* High school mathematics (algebra, trigonometry, basic calculus)
## Course Overview
Model-in-the-Loop (MIL) is the first stage of model-based design. In MIL, both the plant (robot) and the controller are simulated as mathematical models before any code is generated or deployed to hardware. This allows engineers to validate algorithms early, reduce development costs, and identify design issues before testing on physical robots.
