2013-04-18 10:28:53 -0500	asked a question	How to start the etherCAT hand I follewed the instructions on the pages below: http://www.ros.org/wiki/shadow_robot_etherCAT (Shadow Robot etherCAT) and http://www.ros.org/wiki/sr_edc_launch/Tutorials/Starting%20the%20EtherCAT%20Hand (Starting the EtherCAT Hand) there are 3 errors happening `xterm -e roscore & rxconsole & rosrun robot_monitor robot_monitor &` `Unable to register with master node [http://localhost:11311]: master may not be running yet. Will keep trying.` `roslaunch sr_edc_launch sr_edc.launch` `ERROR: cannot launch node of type [pr2_etherCAT/pr2_etherCAT]: can't locate node [pr2_etherCAT] in package [pr2_etherCAT]` `roslaunch sr_hand srh_etherCAT.launch` `ERROR: cannot launch node of type [sr_hand/shadowhand_ethercat]: can't locate node [shadowhand_ethercat] in package [sr_hand]` How to start the shadow robot etherCAT? And the file /opt/ros/fuerte/stacks/sr_config/bashrc/env_variable.bashrc must have been loaded in the `~/.bashrc`?
2013-04-08 08:24:03 -0500	asked a question	How to import sr_robot_msgs in Python I tried to run this code but doesn't work. #!/usr/bin/env python import roslib; roslib.load_manifest('rospy_tutorials') import rospy from std_msgs.msg import * from stacks.shadow_robot.sr_robot_msgs.msg import JointControllerState def callback(data): rospy.loginfo(rospy.get_caller_id()+"I heard %s", data) def listener(): rospy.init_node('listener', anonymous=True) rospy.Subscriber("sh_ffj3_mixed_position_velocity_controller/command", JointControllerState, callback) # spin() simply keeps python from exiting until this node is stopped rospy.spin() if __name__ == '__main__': listener() the answer for this is: `Traceback (most recent call last): File "/home/paulo/ros_workspace/sandbox/beginner_tutorials/scripts/listener.py", line 7, in <module> from stacks.shadow_robot.sr_robot_msgs.msg import JointControllerState ImportError: No module named stacks.shadow_robot.sr_robot_msgs.msg` How to import sr_robot_msgs?

2013-04-04 04:28:38 -0500	asked a question	moving sr_hand ros fuerte with code I tried to move de hand with rostopic and this work very well `rostopic pub /sh_ffj3_mixed_position_velocity_controller/command std_msgs/Float64 -- 10` And I tried to make this with code. `import roslib; roslib.load_manifest('rospy_tutorials') import rospy from std_msgs.msg import * def talker(): pub = rospy.Publisher('sh_ffj3_mixed_position_velocity_controller/command', Float64) rospy.init_node('ffj3Control') value = 10 rospy.loginfo(value) pub.publish(Float64(value)) if __name__ == '__main__': try: talker() except rospy.ROSInterruptException: pass` But this didn't work. The model in the gazebo gui does not move. This the result of this execution: `/opt/ros/fuerte/share/rospy_tutorials$ rosrun beginner_tutorials talker.py[INFO] [WallTime: 1365084692.814065] [0.000000] 10` Anyone knows what is wrong?
