Hello ros users. I am trying to subscribe to base_pose_ground_truth topic but I can't.
My code is this:
nav_msgs::base_pose_ground_truth subs;
double variable1;
double variable2;
void velsubcallback(const nav_msgs::base_pose_ground_truth& msg)
{
variable1=msg.twist.twist.linear.x;
variable2=msg.twist.twist.angular.z;
lectura_ros.linear=variable1;
lectura_ros.angular=variable2;
ROS_INFO("variable %f",lectura_ros.linear);
How can i subscribe on that topic?
Thanks!
