Samples\SimulationTutorials\Beginner\Simple Simulated Robot
We will work from the simulation empty project we created in the previous tutorial. We will also leverage one additional sample service, the EntityUI sample service.
Running an additional sample service
The simulator has the ability to start manifests while it is running. We will use the "EntityUI" service in this tutorial. Start and simulator and select "File" -> "Open Manifest".
Now open the file located at "samples\config\EntityUI.manifest.xml"
Creating a scene
The EntityUI service should and open a WinForm. First let's use the EntityUI to add a basic scene. We can do this by clicking the "Add Default Scene" button shown below.
Now that we have a minimal scene with a sky and a ground plane, let's add a MotorBase entity along with a simulated webcam entity. We want to uncheck all the sensors except the Webcam checkbox. Click "Add Motor Base" to add a motor base with a simulated differential drive and a webcam to your scene (shown below).
Save this scene to some file ("File" -> "Save Scene As...").
Driving the robot with the SimpleDashboard
Now open the manifest that was saved in DSSMe. For example, if you saved your scene to "SimpleRobotScene.xml" the manifest will be saved in the same folder at "SimpleRobotScene.Manifest.xml".
Note the item circled in red in the above picture. The SimulatedDifferentialDrive service, a service that allows for issuing drive commands to a robot, is partnered with the MotorBaseWithDrive entity. This allows the SimulatedDifferentialDrive service to know which entity to issue drive commands to.
Now run this manifest through DSSMe by selecting "Run" -> "Run Manifest". We will use a new service, the SimpleDashboard service, to issue drive commands to the robot. Select "File" -> "Open Manifest..." and open the SimpleDashboard manifest (samples\config\SimpleDashboard.manifest.xml).
The SimpleDashboard service should open a new WinForm, shown below. Click the "Connect" button on the SimpleDashboard service (near upper right of the WinForm).
Now double-click on the "MotorBaseWithDrive" entity listed under the Service Directory. And then click the "Drive" button. Now using the sphere shaped control (boxed in red below) you can drive the robot around.
