Stirling 41l fridge coverJun 12, 2016 · We have modified sample code for the C API so Tango pose data (position (x,y,z) and quaternion (x,y,z,w)) is published as PoseStamped ROS messages. We are attempting to visualize the pose using Rviz. The pose data appears to need some transformation as the rotation of the Rviz arrow does not match the behavior of the Tango when we move it around. →parameter tuning (lidar pose has an unknown time delay and unknown noise) Goal: the ekf_pose should match the gps_local/pose Autoware simulator / Path planning As of this writing, here is what seems to work: the camera needs to be slightly tilted (i.e. not completely flat out) when it starts streaming poses (launching realsense-ros or calling librealsense ’s API to invoke pose data. Otherwise, the yaw angle of the world coordinates might be randomly initialized. GPS is good for 2D position in x-y, but not for heading or velocities of any kind. To solve this problem, ROS provides the robot_pose_ekf node to fuse different forms of sensor data together to use the best of each sensor. For the time being, you could use the GPS and just take a fix-by-fix difference of position to acquire your velocity and heading. gps_gazebo.xacro: If the "gps" parameter is "true", loads the libhector_gazebo_ros_gps plugin to simulate a GPS receiver; p3d_gazebo.xacro: If the "p3d" parameter is "true", loads the libgazebo_ros_p3d plugin for ground truth as an Odometry message (relative to the Gazebo origin).

If there is a priori good map of the environment it is possible to use an Adaptive Monte-Carlo Localization (AMCL) system [18] to obtain the global position of the robot in the map. Conversely, the GPS, and in some cases the magnetometer, run at relatively low sample rates, and the complexity associated with processing them is high. In this fusion algorithm, the magnetometer and GPS samples are processed together at the same low rate, and the accelerometer and gyroscope samples are processed together at the same high rate. Jun 20, 2014 · Publish GPS position in ROS Post by merosss » Fri Jun 20, 2014 4:57 pm Hi everybody, I've started using a GPS module on my quadcopter and till now I've manage to make communicate the two scripts via the `gpsCommunicationTube`, and display the GPS data in a GPS_UI inside the quadcopter script (instead of the gps script). Recent advances in monocular vision based SLAM (ORB_SLAM, LSD_SLAM, SVO) have made it possible to determine a camera's pose w.r.t. an arbitrarily scaled and rotated initial frame. If you combine this information with an IMU and EKF system such as the one from ETH (ethzasl_msf) you can obtain a position estimate even when there is no GPS available. GPS do not provide desired position accuracy and landing with an accurate predefined glide-slope. Differential GPS, or addition of acoustic, laser, or radar altimeters are expensive and do not fit within the Size Weight and Power (SWaP) requirements of a small multi-rotor machine.
