Trying to integrate Amazon Echo to trigger my robot commands via IFTTT to ROS. Anybody has done this before?

indeed, open .yaml file with text editor like gedit, in the first line you will find the path name.

I gave up on Fuerte. Have it now running, using Groovy with Catkin. Now it works for both my Arduino Uno and Arduino ATMega.

Tested it with Adruino 0022 and some earlier versions, also errors. Gave up on Fuerte.

Thanks for your reply! good idea, tested it on Arduino ide 1.0 but same error. Is there somewhere a Fuerte branch that is maintained for more recent Arduino versions?

Hi, could use some help to make rosserial_arduino work and have an arduino work with ROS for me. Have followed all the instructions, tested it on 2 different Arduino's but got the error below and I am out of ideas what I might be doing wrong. I am working on Fuerte, did get Fuerte branch from github (kforce giving errors), was able to rosbuild without errors, have copied ros_lib to sketchbook as instructed. But when compiling the helloword sketch I keep getting error below. Any clues? Thanks

by writing down the question it triggers the mind. Opened the .yaml file and there was a reference of the .pgm file in the /tmp directory. Updated it and now it works.

Hi,

Could use some help on this one.

This one works on my robot (I copy the map files manually to the /tmp directory before roslaunching it):

 <launch>

      <!--- Run the kinect -->
      <include file="$(find turtlebot_bringup)/kinect.launch" />

      <!-- Run the map server -->
      <node name="map_server" pkg="map_server" type="map_server" args="/tmp/my_map_waalre.yaml" />

      <!--- Run AMCL -->
      <include file="$(find turtlebot_navigation)/config/amcl_turtlebot.launch" />

      <!--- Run Move Base -->
      <include file="$(find turtlebot_navigation)/config/move_base_turtlebot.launch" />

    </launch>

But this one not and comes with error

<launch>

  <!--- Run the kinect -->
  <include file="$(find turtlebot_bringup)/kinect.launch" />

  <!-- Run the map server -->
  <node name="map_server" pkg="map_server" type="map_server" args="/home/turtelbot/fuerte_workspace/sandbox/robo/my_map_waalre.yaml" />

  <!--- Run AMCL -->
  <include file="$(find turtlebot_navigation)/config/amcl_turtlebot.launch" />

  <!--- Run Move Base -->
  <include file="$(find turtlebot_navigation)/config/move_base_turtlebot.launch" />

</launch>

So same file but just in a different directory. I must be overseeing something simple. error it produces:

process[map_server-8]: started with pid [20619] process[amcl-9]: started with pid [20630] process[move_base-10]: started with pid [20679] [map_server-8] process has died [pid 20619, exit code 255, cmd /opt/ros/fuerte/stacks/navigation/map_server/bin/map_server /home/turtelbot/fuerte_workspace/sandbox/robo/my_map_waalre.yaml __name:=map_server __log:=/home/turtelbot/.ros/log/531236a0-7aaf-11e3-8077-94dbc9f717d5/map_server-8.log]. log file: /home/turtelbot/.ros/log/531236a0-7aaf-11e3-8077-94dbc9f717d5/map_server-8*.log

Any clues?

Thanks

Ok, will do next time. Note I did not have this comment option before, now I have, something to do with >10 karma (bug?)

I have it now working with a miniGorilla lithion battery connected to the Kinect, works fine.

I have the same question, have my EU turtlebot running but without gyro and wonder if it helps to add. I have US create version pOwerboard with gyro as well and wonder how to connect to din port. Or if I buy seperate gyro how to have it publishing messages? Maybe via Arduino?

Did the Li-ion battery 12v 4800 mAH work with the Kinect?
