| 2015-12-18 00:38:59 -0500 | answered a question | How to interface an Arduino with ROS? Look into ros_arduino_bridge . It uses a lot less memory on the arduino. |
| 2015-12-18 00:23:57 -0500 | asked a question | how to perform localization based on ceiling I've seen localization based on the ceiling image mentioned a few places[1],[2] but its not clear to me if a ros package like RGBDSLAM or RTABMAP can be used with a kinect pointing at the ceiling ? If not, is there another package that can be used to perform SLAM and then localization based on the ceiling ? [1] https://www.ri.cmu.edu/pub_files/pub1...

| 2015-08-03 13:51:36 -0500 | commented answer | ROS dies when wifi disconnects temporarily This is not the problem. The issue isn't that the terminal is closed; the issue is that the wlan0 interface loses its ip for a little bit. In other words, this behaviour happens even if i start the processes locally on the the robot. |

| 2015-07-31 14:49:53 -0500 | asked a question | ROS dies when wifi disconnects temporarily I'm using ROS across two machines: robot and workstation When the wifi on the robot disconnects (might happen when switching AP's), the ros processes die. I tried using 127.0.0.1 for ROS_MASTER and ROS_HOSTNAME which solves the issue but my workstation cannot connect to the robot. I also tried using 0.0.0.0 for ROS_MASTER and ROS_HOSTNAME but ROS doesn't like it. I've also tried ssh port forwarding but ROS uses many ports. The command that I run on the robot is: roslaunch turtlebot_bringup minimal.launch and roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml The command that I run on the wokstation is roslaunch turtlebot_rviz_launchers view_navigation.launch How to solve this issue ? |
