Valkyrie model spawn error
I'm trying to spawn a Valkyrie robot in Gazebo's
rosrun and so far I got this error every time I did it.
[ INFO] [1477943898.800700118, 0.022000000]: waitForService: Service [/gazebo/set_physics_properties] is now available. [ INFO] [1477943898.827596901, 0.047000000]: Physics dynamic reconfigure ready. Error [parser.cc:697] XML Element[imuTransform], child of element[sensor] not defined in SDF. Ignoring.[sensor] Error [parser.cc:688] Error reading element <sensor> Error [parser.cc:688] Error reading element <link> Error [parser.cc:688] Error reading element <model> Error [parser.cc:348] Unable to read element <sdf> Error [parser.cc:299] parse as old deprecated model file failed. Error [World.cc:1527] Unable to read sdf string [...the whole text from urdf file...]
Can somebody explain why I have this error and suggest any potential solution for this? Thank you.
