Student Competition: Mobile Robotics Training, Part 5: Performing a Sequence of Path Navigation Tasks

Learn how to design a supervisory logic that navigates a robot through a predefined path and perform a sequence of tasks.

In this final video of the series you will learn how to design a supervisory logic in Stateflow^® that will help in combining a sequence of tasks like dead reckoning, line following and obstacle detection. You will see how this logic can be designed with both on-off and PID-based algorithms implementations of these tasks.

In this video, you will also use the Simulation Map Generator App to create an common map from an actual image of the game field or course for both line track and obstacle location. You will learn how to use the generated map for simulating and testing your algorithms within Simulink.

A VEX EDR robot is used to demonstrate the performance of the path navigation tasks on the microcontroller.
