Covering polygonal scenes

The applet

This applet implements a simulation environment for exploration (covering) strategies in polygonal scenes. Such strategies are needed for the design of service robots such as lawn movers or cleaning devices. Thus, we deal with rather simple and cheap robots; especially, the robot do not have an expensive vision system and are equipped only with touch sensors. Moreover, the robot has limited ressources regarding computational abilities, memory and provision of electricity.

We assume that the robot has no map of its surrounding in advance, so we deal with online strategies.


Usage

The applet consists of two main views that can be switched using the windows menu: The polygon explorer is used to simulate strategies, and the polygon editor is used to enter and edit the robot's surrounding.

Polygon-Editor

Canvas

In the edit mode, you can draw and edit polygons on the canvas by dragging the mouse while pressing the left butten or entering single points with a left-button click. Please draw the obstacles inside the environment first, and draw the bounding polygon afterwards. A right click open a popup menu with several edit functions such as moving, copying, scaling, rotating or deleting polygons.

Polygon-Explorer

Canvas

The explorer view is used to simulate covering strategies in the given scene. After you have selected a strategy, you see a robot in the main canvas. You can set the robot's start point with the context menu (right mouse button), and edit the robot's shape using the robot editor. To start a strategy, press the run or the step button.
