Hi all,<br>I&#39;m trying to subscribe to the cmd_vel message, According to the definition, the message is of type Twist, with 2 vectors linear and angular.<br>My node to access this topic is in python.<br>For example, if the subscriber is vel = rospy.Subscriber(&quot;/cmd_vel&quot;, Twist)<br>
if i try to print out vel.linear, it gives an attribute error, stating the subscriber object has no attribute linear.<br><br>Any idea what I&#39;m doing wrong here?<br clear="all"><br>-- <br>Regards,<br>Hitesh Dhiman<br>Electrical Engineering<br>
