Now the topic is enabled, however no anycodings_ros messages are published, while I'm expecting anycodings_ros to see messages of type anycodings_ros "webots_ros/Int8Stamped", which should give anycodings_ros me zeros for the absence of a suitable anycodings_ros connector. In the next step anycodings_ros I enable the Connector using its anycodings_ros corresponding service, where an integer anycodings_ros needs to be specified (presence check Time anycodings_ros Step) //presence_sensor/enable service as anycodings_ros shown below: When I run the simulations all ROS services anycodings_ros are advertised as expected. My first step was to anycodings_ros just take one of the robots of the anycodings_ros "connector.wbt" world and place it in a new anycodings_ros world and switching the robots controller anycodings_ros argument to "ros"as one can see below. The name of e-puck matches the world file.I'm currently trying to make the Connector anycodings_ros Device work with ROS. I tried calling different methods on epuck, and they all resulted in NullPointerException. Index Inheritance Abstract Nodes Bounding Objects Insertion Rules Inheritance In the chart, an arrow between two nodes represents an inheritance relationship. at SupervisorController.main(SupervisorController.java:497)Įpuck variable is null. The Webots Node Chart outlines all the nodes available to build Webots worlds. at SupervisorController.initialise(SupervisorController.java:413) what is obviously wrong, since it leaves x-3 without a connection to the node. This is what I'm doing in SupervisorController: 412 Node epuck = getFromDef("epuck") Ĥ13 Field fldTranslation = epuck.getField("translation") Īnd as a result I get this exception: Exception in thread "main" Formerly I presented a metric navigation method in the Webots mobile. Robots are communicating via Emitter and Receiver, and everything works fine but the position reset. In the other hand, Webots also adds many nodes, which are not part of the VRML97 standard, but are specialized to model robotic experiments.
