I am trying to add a camera to the iris drone to my gazebo simulation. I tried using many models (iris_fpv_cam, iris_downward_depth_camera, iris_stereo_camera …) by changing px4 launch files’ vehicle argument. But i keep getting:
Error: Unknown model 'iris_fpv_cam' ERROR [px4] Startup script returned with return value: 256
I also tried to modify iris.sdf and iris.xacro files as described here. And I get the following errors:
Error [parser.cc:550] Required attribute[name] in element[collision] is not specified in SDF. Error [parser.cc:769] Error reading element <collision> Error [parser.cc:769] Error reading element <link> Error [parser.cc:769] Error reading element <model> Error [parser.cc:394] Unable to read element <sdf> Error: Could not find the 'robot' element in the xml file at line 81 in /build/urdfdom-UJ3kd6/urdfdom-0.4.1/urdf_parser/src/model.cpp Error [parser_urdf.cc:3408] Unable to call parseURDF on robot model Error [parser.cc:340] parse as old deprecated model file failed.
Can someone please assist me on how to add a downward camera attached to my drones?
