This document introduces the demo project of "artifacts_demo", explaining user operation of Virtual Wall/Virtual Track, including how to add/delete/modify artifacts.

IDE Preparation 

  • Software

    • Visual Studio 2010  SP1
    • Slamware Windows SDK:Slamware Windows SDK
    • RoboStudio(for map display):Robostudio installer 

    • Sample Code: 

      Higher version of Visual Studio will cause errors. sometime you will need to upgrade SP1 package to make your VS compatable with .Net Framework.

  • Hardware

          （Either one of following）

    • Slamware SDP mini 
    • Slamware SDP
    • Slamware Kit 
    • Zeus/Apollo robot base

Win32-Demo

Compiling

  1. Right click on "artifacts_demo" project, set as StartUp project.


  2. Right click on "artifacts_demo", then " Properties"，configure "include" and "lib" directories to the corresponding folder path of Slamware SDK.

    It's not necessary to copy files to the project directory, user will only need to configure the folder path of SDK.




  3. Right click on "artifacts_demo", then "properties"，set "Command Arguments"  as follows:  
    Syntax ：artifacts_demo <IP address>


  4. Click " F5" to execute.
  5. In robostudio, the output will be as follows:


  6. The output from console will be as follows:


  7. Delete one of the virtual tracks by selecting one of the IDs. the ID selected in the video is 3.

Code

  • Delete all virtual tracks/walls.
删除所有虚拟轨道/虚拟墙
		SlamwareCorePlatform sdp = SlamwareCorePlatform::connect(argv[1], 1445);
        std::cout << "Clearing existing tracks and walls..." << std::endl;
		sdp.clearLines(ArtifactUsageVirtualTrack);
		sdp.clearLines(ArtifactUsageVirtualWall);
  • Add virtual walls
添加虚拟墙
		std::cout << "Adding virtual walls..." << std::endl;
		std::vector<Line> walls;
		//add a 8 * 8 virtual wall square
		walls.push_back(Line(Point(-4, -4), Point(-4, 4)));
		walls.push_back(Line(Point(-4, 4), Point(4, 4)));
	    walls.push_back(Line(Point(4, 4), Point(4, -4)));
		walls.push_back(Line(Point(4, -4), Point(-4, -4)));	
		sdp.addLines(ArtifactUsageVirtualWall, walls);
  • Add virtual tracks
添加虚拟轨道
		std::cout << "Adding virtual tracks..." << std::endl;
		std::vector<Line> tracks;
		//add a 2 * 2 virtual track square
		tracks.push_back(Line(Point(-1, -1), Point(-1, 1)));
		tracks.push_back(Line(Point(-1, 1), Point(1, 1)));
		tracks.push_back(Line(Point(1, 1), Point(1, -1)));
		tracks.push_back(Line(Point(1, -1), Point(-1, -1)));	
		sdp.addLines(ArtifactUsageVirtualTrack, tracks);
  • Modify a virtual wall ( similar with virtual wall modification)
移动虚拟墙
		std::cout << "Moving vitual walls..." << std::endl;
		//sleep 5 seconds for displaying purpose only, not necessary
		boost::this_thread::sleep_for(boost::chrono::milliseconds(5000)); 
		std::vector<Line> get_walls = sdp.getLines(ArtifactUsageVirtualWall);
		//shrink virtual wall square from 8 * 8 to 6 *6
		for (std::vector<Line>::iterator it = get_walls.begin() ; it != get_walls.end(); ++it) {	
            it->startP().x() *= 0.75f; 
            it->startP().y() *= 0.75f;
		}
		sdp.moveLines(ArtifactUsageVirtualWall, get_walls);
  • Delete virtual tracks( similar with virtual wall deletion）
删除指定虚拟轨道
		std::cout << "Get all tracks..." << std::endl;
		std::vector<Line> get_tracks = sdp.getLines(ArtifactUsageVirtualTrack);
		for (std::vector<Line>::iterator it = get_tracks.begin() ; it != get_tracks.end(); ++it) {
			std::cout << "ID: " << it->id() << std::endl;
			std::cout << "Start from (" << it->startP().x() << " , " << it->startP().y() << ") " << "to (" 
				      << it->endP().x() << " , " << it->endP().y() << " ) " << std::endl;		
		}

		std::cout << "Delete track by ID, please enter track ID:" << std::endl;
		int id;
	    bool is_found = false;
		std::cin >> id ;
		for (std::vector<Line>::iterator it = get_tracks.begin() ; it != get_tracks.end(); ++it) {
			if (id == it->id()) {
				sdp.removeLineById(ArtifactUsageVirtualTrack, id);
				is_found = true;
				break;
			}
		}
		if(!is_found)
			std::cout << "Wrong ID" << std::endl;
