To create a decent map, I teleop pepper with a slow movement and trying to give key points at gmapping package since have a high probability to understand where is the position of the robot on the map and add the new information to build the new part of the map. A Kalman filter based algorithm is proposed to improve the loop closure correction performance of Gmapping using low cost and resolution laser scanners (e. As Hurricane Dorian churned across the Bahamas Monday (Sept. It has been heavily tested. The map I'm using is generated from a pgm file using gmapping in ROS. On the control side, Forward Back-ward Sweep Method is used to generate locally optimal trajectories and the correspond-ing feedback control law. It doesn't seem to make a difference. Tolic D, Fierro R. Hgmm Point Cloud Matching pose relationship to odom and output accuracy. The output of the mux ties into the vesc/ackermann topic. Free Map Tools.
