Question

Hello everybody,

I am using the Robotics Toolbox with Matlab R2015a. I am able to do the binding with ROS. But I can't use the topic /tf and I have an error using rostf:

>> rostf
ans = 
    TransformationTree with properties:
      AvailableFrames: {0x1 cell}
       LastUpdateTime: [0x1 Time]
[ERROR] SubscriberHandshakeHandler - Subscriber handshake failed: Message types don't match.
[ERROR] SubscriberHandshakeHandler - Subscriber handshake failed: Message types don't match.
[ERROR] SubscriberHandshakeHandler - Subscriber handshake failed: Message types don't match.
[ERROR] SubscriberHandshakeHandler - Subscriber handshake failed: Message types don't match.

It is a problem for me as I need to extract the position of several joints in world coordinates. The robot I am using in Gazebo is the PR2. If you have any ideas, don't hesitate.

Thank you.
