This package shows how to get started with the LEGO Mindstorms EV3 support from Simulink and build an obstacle avoiding rover. This uses the Simulink support package to communicate with the robot and uses Simscape Multibody for the 3-D simulation environment.
This project shows how Simulink helped us - 1) simulate and understand robot behavior before deploying the same code onto the robot and 2) Tune parameters and monitor signals from Simulink while the code is still running on the robot without having to recompile. The project also shows basics of Control System Design - data acquisition, parameter estimation and motor controller design.
