Hi,
I want to see the simulation of what my Lego NXT is doing with rviz.
Therefore I created the model of my robot with Lego digital designer and the converted it in the right format, that is to say in a .urdf file.
I renamed my sensors and motors with the name that I specified in the .yaml file.
But when I run rviz I get:
Robot Model
Status Error
ref_0_link No trasform from [ref_0_link] to [/world]
...
In my nodes I specified a tf between the robot base frame and the world frame, and another between the ultrasonic sensor frame and the robot frame.
In fact the links robot and ultrasonic_sensor are the only ones with Transform Ok
.
I thought that because of the fact the all the links are children of robot and the joint are fixed there is no need to specify a tf for every link.
Can anyone tell me how to solve my problem?
