I am working on a drone project I’m connecting ros to gazebo and using the mavros node of course. @JayanthAmmapalli MAVROS uses MAVLink to talk to the AP. x=1. What I confused is default definition of body frame. Sign up for free to join this conversation on GitHub. msg, I found the following definition for frame. sp = PositionTarget() self. My first idea was to use /mavros/setpoint_velocity/cmd_vel and set the fcu into OFFBOARD mode. I tested the /mavros/setpoint_velocity/local, however saw (simulator SITL) UAV rotate when the altitude decrease or increase and give me other different behavior, also I remember use Quaternion to modify the UAV pose, but honesty I don't Saved searches Use saved searches to filter your results more quickly Saved searches Use saved searches to filter your results more quickly [1] Lee, Taeyoung, Melvin Leoky, and N. raw. py: Contains core controller class; waypoint. 0 ROS: Foxy Ubu Corresponding topic is /setpoint/relative_pos; apriltag_setpoint_publisher. However, whenever I utilize the mavros/setpoint_velocity/cmd_vel topic to command the vehicle, I see very accurate results even though the vehicle is in a GPS denied environment. I am trying to use the fake_gps feature of mavros in gps-denied environment. From my understanding of the example code, given a goal position and velocity it will generate coefficients for a polynomial trajectory of message type PolynomialSegment. I have a code written with python using mavros to control iris drone in offboard mode. 17) frame conversion changed again Since 2016-06-22 (pre v0. Example: velocity setpoint in body frame = [2, 0, 0] x points to the front, y points to the left and z points to the top (ROS convention for base_link Hi, I am trying to control all axes of quad-copter. Though mavros publishes a lot of different topics, we will examine /mavros/imu/data as for example. You signed in with another tab or window.
