Obstacle avoidance

1. Overview

MRPT comprises several classes related to obstacle avoidance or reactive navigation:

For realistic robots:

• The PTG-based reactive navigation engine, which internally employs one of the holonomic navigators below.
• The complete GUI simulator: ReactiveNavigationDemo.

For holonomic robots (i.e. can move in any direction): See the video of the app holonomic-navigator-demo and the C++ classes:

• Nearness-Diagram implementation
• VFF (Virtual Force Fields or Potential Fields).
