2016-03-17 05:43:49 -0500 | asked a question | nav2d using Gazebo hi, I am trying to use nav2d using Gazebo. I am using "https://github.com/skasperski/gazebo_robots" launch file and added rviz. When I try to set goal in rviz I am getting error as <launch> <include file="$(find gazebo_ros)/launch/empty_world.launch"> <arg name="world_name" value="$(find scout)/world/willow.world"/> <arg name="paused" value="false"/> <arg name="use_sim_time" value="true"/> <arg name="gui" value="true"/> <arg name="headless" value="false"/> <arg name="debug" value="false"/> </include> <node name="RVIZ" pkg="rviz" type="rviz" args=" -d $(find nav2d_tutorials)/param/tutorial3.rviz"/> </launch> I commented group ns because it publishes topics with prefix "scout" which doesn't creates problem in loading robot in rviz. I am trying to repeat the tutorial 3 with gazebo and rviz. Where I am going wrong.Kindly correct me. Thanks in advance. |

2016-03-13 23:01:33 -0500 | commented question | Rosserial_xbee fails to connect xbees Is it the problem in software serialnode.py or hardware? Hope there wont be problem in hardware connection bcz of same hardware tested in X-CTU.So what I can do in software |
2016-03-13 23:00:11 -0500 | commented question | Rosserial_xbee fails to connect xbees Xbee end device RSSI is blinking means it can receive data from co-ordinator. But CO-orninator RSSI never turns up. Means its not receiving sync from end device.SO what might be the problem in end device |
2016-03-13 22:58:08 -0500 | commented question | Rosserial_xbee fails to connect xbees The device is actually connected to " /dev/ttyUSB0 ". Even I verified earlier. I am tyring to narrow down the problem to know who is the root cause. Problem is not with xbee:bcz xbee can communicate in X-CTU using windows. Xbee configuration doesn't have any problem. |
2016-03-13 20:53:22 -0500 | answered a question | Rosserial_xbee fails to connect xbees Hi, I checked with the device connection before itself as well as now with your command. Still same problem. I am able to check the rostopic.Which is published by Xbee as /diagnostics **header: seq: 14 stamp: secs: 1457920159 nsecs: 757045984 frame_id: '' status: Any Idea now??.. But what i think is co-ordinator able to communicate with End device with board. The end device is not able to connect with master it seems. I dont know whats the problem. |
2016-03-11 00:36:24 -0500 | asked a question | Rosserial_xbee fails to connect xbees My Xbee works fine with X-CTU in windows. When I try to transfer data between XBee- end device with arduino to Xbee-coordinator connected to PC using I am getting following error : I followed the http://wiki.ros.org/rosserial_xbee/Tu... tutorial which works fine for me the first time. But now its not working.I didn't change any version after that. I am using ROS Hydro on Ubuntu 12.0.4 Sparkfun Xbee Kit series 1. Can anyone please help me to solve this problem. |
2016-03-10 22:09:30 -0500 | answered a question | ROS Serial Xbee - Unable to sync with device Hemant: did u solve the xbee issue? I am facing the same problem. It works the first time. Two days later "Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino". I tried installing again. It's working in X CTU. |
