[控制算法]
mavros offboard 位置控制
2阿木币
我根据官网教程,修改demo的代码,想让无人机在gazebo里飞一个矩形后在降落,代码如下:
#include <ros/ros.h>
#include <geometry_msgs/PoseStamped.h>
#include <mavros_msgs/CommandBool.h>
#include <mavros_msgs/SetMode.h>
#include <mavros_msgs/State.h>
/*
#include <cstdio>
#include <unistd.h>
#include <termios.h>
#include <fcntl.h>
*/
mavros_msgs::State current_state;
void state_cb(const mavros_msgs::State::ConstPtr& msg){
current_state = *msg;
}
bool begin_hhh = false;
int main(int argc, char **argv)
{
ros::init(argc, argv, "offboard_node");
ros::NodeHandle nh;
ros::Subscriber state_sub = nh.subscribe<mavros_msgs::State>
("mavros/state", 10, state_cb);
ros::Publisher local_pos_pub = nh.advertise<geometry_msgs::PoseStamped>
("mavros/setpoint_position/local", 10);
ros::ServiceClient arming_client = nh.serviceClient<mavros_msgs::CommandBool>
("mavros/cmd/arming");
ros::ServiceClient set_mode_client = nh.serviceClient<mavros_msgs::SetMode>
("mavros/set_mode");
//the setpoint publishing rate MUST be faster than 2Hz
ros::Rate rate(20.0);
// wait for FCU connection
geometry_msgs::PoseStamped pose;
pose.pose.position.x = 0;
pose.pose.position.y = 0;
pose.pose.position.z = 2;
geometry_msgs::PoseStamped pose1;
pose1.pose.position.x = 2;
pose1.pose.position.y = 0;
pose1.pose.position.z = 2;
geometry_msgs::PoseStamped pose2;
pose2.pose.position.x = 2;
pose2.pose.position.y = 2;
pose2.pose.position.z = 2;
geometry_msgs::PoseStamped pose3;
pose3.pose.position.x = 0;
pose3.pose.position.y = 2;
pose3.pose.position.z = 2;
geometry_msgs::PoseStamped pose4;
pose4.pose.position.x = 0;
pose4.pose.position.y = 0;
pose4.pose.position.z = 2;
geometry_msgs::PoseStamped pose5;
pose5.pose.position.x = 0;
pose5.pose.position.y = 0;
pose5.pose.position.z = 0;
//send a few setpoints before starting
for(int i = 100; ros::ok() && i > 0; --i){
local_pos_pub.publish(pose);
ros::spinOnce();
rate.sleep();
}
mavros_msgs::SetMode offb_set_mode;
offb_set_mode.request.custom_mode = "OFFBOARD";
mavros_msgs::CommandBool arm_cmd;
arm_cmd.request.value = true;
ros::Time last_request = ros::Time::now();
while(ros::ok()){
ros::spinOnce();
if( current_state.mode != "OFFBOARD" &&
(ros::Time::now() - last_request > ros::Duration(5.0))){
if( set_mode_client.call(offb_set_mode) &&
offb_set_mode.response.success){
ROS_INFO("Offboard enabled");
}
last_request = ros::Time::now();
} else {
if( !current_state.armed &&
(ros::Time::now() - last_request > ros::Duration(5.0))){
if( arming_client.call(arm_cmd) &&
arm_cmd.response.success){
ROS_INFO("Vehicle armed");
}
last_request = ros::Time::now();
}
}
ROS_INFO("yo yooooooooooooooooooooooo");
begin_hhh = true;
ros::spinOnce();
local_pos_pub.publish(pose);
ros::Time time_1 = ros::Time::now();
while(time_1.sec ==0){
time_1 = ros::Time::now();
}
time_1 = ros::Time::now();
while(1){
local_pos_pub.publish(pose);
rate.sleep();
ROS_INFO("Get pose !!!!!!!!!!");
ros::Time time_2 = ros::Time::now();
while(time_2.sec - time_1.sec >10){
local_pos_pub.publish(pose2);
ROS_INFO("hhhhhhhhhhhhhhhhhhhhh ??????????????");
rate.sleep();
}
}
ros::spinOnce();
}
return 0;
}
但是运行后,gazebo里无人机依然只是起飞到离地2米处,无其他动作,代码哪里出错了?(甚至后面添加的打印语句如“yo ooooooooo”都打印不出了),
绞尽脑汁,始终无果,实属无奈,寻求大佬帮助!!!

这个代码这样写是有问题的,正确的做法是读取当前无人机的位置,判断无人机到达矩形的一个点过后然后发送下一个点

这种只能看AmovlabQYP他们做视觉无人机的对这一块比较熟,是不是你这个代码都没正常运行哦。Offboard enabled那些消息打印出来了吗 |

每个地方都加上打印 不就能简单的定位出错位在的地方了?
代码太长。。不想看。。 |
