I think the /setpoint_raw/local topic is the right one for this, however it's not behaving like the /setpoint_velocity/cmd_vel. rviz things must be in separate node; later cleaned plugin may be added to libmavros_plugins. While commands on y- and y- axis result in a smooth, correct motion, commands on the z-axis lead to a sudden jump in z-velocity and therefore height. com Assunto: Re: [mavros] Add topics for orientation control setpoint. Issue details Hi everyone, I want to send my quadcopter to the latitude, longitude and altitude coordinates I I was using /mavros/rc/override on a pixhawk 1 in order to control the rover via an external pc, and this worked just fine. 0 and its better to uncheck Issue details. For example, if Kp_z is too large, there might be an overshoot problem on z-axis. I have also /mavros/setpoint_attit All, My apologies by slow reply, but I was working on other different things and I was now hable to response before. Instead of rely on '/mavros/setpoint_position/local' to achieve the altitude hold, I might as well write my own PID altitude controller that takes the difference of the desired altitude and my current altitude (set_z - measured_z) as my input, and output velocity control in the z direction. I have been able to get into offboard mode, but the drone won't arm (red flashing led indicator). 21. # see enum MAV Corresponding topic is /setpoint/relative_pos; apriltag_setpoint_publisher. py: This node takes the pose of the detected tag and computes relative positino setpoints which are published to /setpoint/relative_pos topic. sp.

In those messages, using the proper uint16 type_mask (see for example this issue for more details) you can combine relative vx,vy Issue details Dear team, I am currently using setpoint_raw/local to control my drone indoor with a tfmini rangefinder. By the way, I found that with firmware developers that this to work we have to send a Mavlink msg to change the FCU mode to OFFBOARD and for that a valid setpoint must be recieved first in the FCU so that OFFBOARD mode is enabled and the i think there is a problem with the rotation of the velocity in the setpoint_raw plugin if you specify a velocity in the body frame the movement is different to the setpoint_velocity plugin. As far as I see I can either send acceleration offboard or position, velocity offboard is that correct? Can we just send all? I can see that px4 supports it and we can achieve similar behavior to send a attitude setpoint (with quaternion in this case). But I can't understand, ho Issue details Finding information for MAVROS2 has been pretty frustrating as relevant information seems scarce. I'm using mavros on an intel joule.

This experiment requires custom RC inputs. io/mavros_tutorial/ This is a python implementation of the MAVROS You can use the PointTarget message of topic /mavros/setpoint_raw/local to takeoff to a certain height and start publishing velocity commands instead of position. Issue Details My goal is to write a ROS2 node that can command an IRL drone to move forward and backwards using: CubeOrangePlus as the FCU Raspberry Pi 4B as an onboard computer. MAVROS version and platform. If body frame is configured as forward for x axis, yaw will be 0 degree when I put UAV`s direction to east and it is equal to when I test with real environment. I think the apm still cannot connect to the FCU If no mission received, aircraft will LOITER at current position instead. We can't seem to properly configure the distance_s If your mocap node is sending this same data in another topic name (/tf or /robot/pose/ for example), you should remap the MAVROS topic (mavros/mocap/pose) to the name of these topics or vice-versa (remap these topics to mavros/mocap/pose), on the launch file.

Issue details Hello Everyone, I am attempting to control a quadcopter‘s position using a camera to move to a target using the difference between the current location of the drone and the centroid of a target. self. I have been using ~setpoint_velocity/cmd_vel (geometry_msgs/TwistStamped) messages, but This project illustrates some examples about simulating robots via Ardupilot-SITL using python and C++ languages and MAVROS (MAV-link protocol for Robotic Operating System). publish(pose); to move towards certain waypoint in the space. Topics The drone still moves in attitude when the /mavros/setpoint_position/local is disabled and start the /mavros/setpoint_velocity/cmd_vel topic. Able to Arm but not able to issue take off command. To do this, I am using the c It turns out that, since I have no RC controller, I have to alternatively CONTINUOUSLY publish something to /mavros/setpoint_raw/local or /mavros/setpoint_raw/global. Issue details Hi, I am new to Mavros and ROS so please be patient :) I am trying to read IMU linear acceleration data directly from a Pixhawk (connected via USB) with a C++ program without success. As far as I know, MAVROS switched from mavros_msgs::GlobalPositionTarget to geographic_msgs::GeoPoseStamped, which is not documented in the wiki. lsqcsfuwxykhrivzvptgafqlswdzenoawircizzruyhhrbqryykzrr
