2015-04-26 19:25:56 -0500 | asked a question | Can't find correct sytax for ros::nodehandle::advertise I have just started learning ROS and I have written a publisher node based on the following tutorials: https://support.clearpathrobotics.com... ------ ROS 101: Drive a Husky http://wiki.ros.org/ROS/Tutorials/Wri... I can't get it to compile, and after checking the tutorials and trying to understand the correct syntax I have been left completely baffled. I have no idea how to fix the problem. The problem is on line 28: ros::Publisher velocity_pub = node.advertise<geometry_msgs twist="">(topic_name, 1000); I am very new to ROS. Can someone explain how to correctly write a ros::nodehandle::advertise statement? Here is the console output: And here are my files: drive.cpp: (more) |
2015-04-12 22:08:21 -0500 | asked a question | Unable to get ROS Husky Simulation Tutorial to Work I have just started using ROS, and have been using the Clearpath Robotics tutorials to get my head around it. They have a tutorial 'Drive a Husky' https://support.clearpathrobotics.com... I have installed the components and I can load up the Gazebo simulator and RViz, however when I get to the line nothing happens. According to the tutorial this is supposed to make the robot in the simulation move forwards. This may be something trivial that I have overlooked but I am very new to ROS and have no idea how to troubleshoot the problem. All the answers I have come accross so far just say that entering the command into a new terminal window will work - but it doesn't. I am using ROS Indigo on Mint 17.1 Rebecca. |
