Simulated LRF
The SimulatedLRF service demonstrates how to simulate a laser ranger finder using the simulation engine's raycast capabilities.
This sample is provided in the C# language. You can find the project files for this sample at the following location under the Microsoft Robotics Developer Studio installation folder:
Samples\Simulation\Sensors\LaserRangeFinder
Contents:
- Setting Up the Service
- Running the Service
Prerequisites
Hardware
This service requires no special hardware apart from a suitable graphics card to run the Simulator.
Software
This software is designed to run with Microsoft Robotics Developer Studio.
Setting Up the Service
The SimulatedLRF service is installed automatically with RDS. The sample that shows usage of the SimulatedLRF service is the simulation tutorial Multiple Simulated Sensors.
The SimulatedLRF implements the Laser Range Finder service contract so that it can be used by other services.
Running the Service
There are two different methods to start the SimulatedLRF service. Either:
Start the service by adding the service to a manifest either through DSS Manifest Editor (DSSME) or manually with any text editor. The below XML shows how the SimulatedLRF service should appear in the manifest.
<?xml version="1.0"?> <Manifest xmlns:simulation="https://schemas.microsoft.com/robotics/2006/04/simulation.html" xmlns:simulatedlrf="https://schemas.microsoft.com/robotics/simulation/services/2006/05/simulatedlrf.html" xmlns:this="urn:uuid:1ec97e0a-7369-44eb-a5a6-5d29767af745" xmlns:dssp="https://schemas.microsoft.com/xw/2004/10/dssp.html" xmlns="https://schemas.microsoft.com/xw/2004/10/manifest.html"> <CreateServiceList> <!--Any other services you want to start could be here--> <ServiceRecordType> <dssp:Contract>https://schemas.microsoft.com/robotics/simulation/services/2006/05/simulatedlrf.html</dssp:Contract> <dssp:PartnerList> <dssp:Partner> <dssp:Service>https://localhost/LaserRangeFinderEntityName</dssp:Service> <dssp:PartnerList /> <dssp:Name>simulation:Entity</dssp:Name> </dssp:Partner> </dssp:PartnerList> <Name>this:SimulatedLaserRangeFinder</Name> </ServiceRecordType> </CreateServiceList> </Manifest>
Start the service programatically as done in a program that generates a simulation environment:
Microsoft.Robotics.Services.Simulation.Sensors.LaserRangeFinder.Proxy.Contract.CreateService( ConstructorPort, "https://localhost/" + lrfEntity.State.Name, Microsoft.Robotics.Simulation.Partners.CreateEntityPartner( "https://localhost/" + lrfEntity.State.Name) );
