How to properly use get_sensor?

asked 2017-01-16 03:37:56 -0500

Hi,

I have some code which uses get_sensor to get a laser sensor, however when I want to use two of this model, they get muddled up as I can't reference the full model name.

sensors::SensorPtr model_sensor;

model_sensor = sensors::get_sensor("laser"); // this is fine when there's only one laser sensor

I want to get something like:

model_sensor = sensors::get_sensor("my_model::hoyoko::link::laser"); but I'm confident this is wrong as gazebo crashes with this new code.

I have the get_sensor refference : http://osrf-distributions.s3.amazonaw... (Ctrl f "get_sensor" to find the relevant part)

But I don't fully understand what they mean by " This name should be fully scoped. This means _name = world_name::model_name::link_name::sensor_name."

Any help would be much appreciated, thanks!

Thanks for posting your solution. I'm curious, what do you mean by "the whole thing" if it's not the scoped name? Maybe this is a bug in Gazebo, it shouldn't crash with a bad string.

If I try to find the sensor without the world name, i.e: sensorLocation = /*"default::" +*/ this->model->GetName() + "::hokuyo::link::laser"; the get_sensor function will crash. But it will work fine if I either include all the names, or just the sensor name. The whole thing is: sensorLocation = "default::" + this->model->GetName() + "::hokuyo::link::laser"; Just the sensor name is: sensorLocation = "laser";
