Re: [ros-users] joy_node communication problem

Hi Antonio

you probably changed from diamondback(or earlier)
to ROS electric:

See: http://www.ros.org/doc/api/joy/html/msg/Joy.html
joy/Joy.msgs
is depricated.

# This message is deprecated please use the sensor_msgs/Joy
float32[] axes
int32[] buttons

You will have to change the callback to
sensor_msgs/Joy

Betreff: [ros-users] joy_node communication problem


Hi,

I'm trying to run the tutorial "Writing Teleoperation Node for a Linux supported Joystick" ( http://www.ros.org/wiki/joy/Tutorials/WritingTeleopNode ) but, when I launch it, this errors occurs:

[ERROR] [1319554411.613621554]: Client [/teleop_nao] wants topic /joy to have datatype/md5sum [joy/Joy/e3ef016fcdf22397038b36036c66f7c8], but our version has [sensor_msgs/Joy/5a9ea5f83505693b71e785041e67a8bb]. Dropping connection.

Any ideas on how to fix the problem?

My computer is running Ubuntu 10.04 and I'm using ROS electric.
