Update RosAria
Have you tired grabbing the latest version of RosAria from github today? A fix has recently been applied for this kind of issue:
https://github.com/amor-ros-pkg/rosaria
Launch RosAria
In a terminal, run the ROS master server:
$ roscore
In another terminal, run the robot driver (RosAria):
$ rosrun rosaria RosAria
In another terminal, verify topics are being published:
$ rostopic list
If you don't see any topics listed, something is wrong with your ROS Environment settings. http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment
TicksMM et al:
When rosaria launches, it will set TicksMM et al from the ROS parameter server iif they are set. If the parameters are not set, it will read the values from the robot's EEPROM and set them. There are a few ways to tune them if needed:
- dynamic_reconfigure
- launch file
- @launch via _TicksMM:=XXX
- There is a tool that lets you change the value in the robot's EEPROM from adept (I dont remember what it's called but you can find it on their wiki)
Test robot motion with:
$ rostopic pub -1 /RosAria/cmd_vel geometry_msgs/Twist '{linear: {x: 0.05, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'
* Still having problems? *
If you are still are having problems, post the output of rosrun rosaria RosAria and I'll see what I can do for you. :)
what value of TicksMM allows your robot to move?
It had worked for a TicksMM value of 128 the last time that we ran the robot
What is the output of $ rostopic list
no output...the cursor blinks and nothing happens...
