Reactive-Navigation

  • In Reactive Navigation the navigation is executed purely based on the processing of the current/recent sensor data.

  • Reactive Navigation does not include a map and hence the position of the robot with respect to a global frame of reference is not known.

  • Using Reactive Navigation a robot can navigate in completely unknown environments containing unpredictable moving obstacles.

Implementations:

  1. Follower application between two turtlesim robots:
    • One turtlesim robot is teleoperated and the other follows it.
    • One frame of reference is attached to each turtlesim robot and the relative transformation between these two frames is calculated.
    • Then, control commands are given such that it follows the teleoperated robot using feedback control.
