When I run the robot commander app I see there is a “find (target)” option.
What are the list of “targets” and can I add some of my own as well?
If you look at the documentation here:
You can see that this uses the inbuilt DNN coupled to the camera to find objects in the room. It can recognize about 20 different pre-trained objects namely:
aeroplane, bicycle, bird, boat, bottle, bus, car, cat, chair, cow, dining table, dog, horse, motorbike, person, potted plant, sheep, sofa, train, tv monitor
You can add your own but you’d need to re-train the DNN on the robot to do that - this is non-trivial.

In all my attempts to find objects using the robot commander app I have yet to get Magni to move or find any object.
What gives?

You need to have the dnn node (deep neural network based classifier) running on the robot before you can have this functionality work.
On the robot run:
roslaunch magni_demos dnn_rotate.launch

Is there a way to know whether the dnn node is running?
You can run rosnode list and see if dnn_detect and dnn_rotate are running.
I was reading this thread and was interested to test it out,
when I command ‘‘find person’’, Magni just “rotates 360 degrees” to find a person, on the same spot and does not actually “move” around the room to find a person, why is that?
and also if the person is a bit far away , but within line of sight, Magni does not recognize the person and instead just rotates to a wall and returns back “rotated to person” , do you know why?
but even if Magni has found a person (I have to be very close to it…) , it just “rotates to point to the person” , it does not move close to the person…,
is there a version that actually makes Magni to “move” around the room to find objects?
instead of just rotating on the same spot everytime…, (because the room is bigger and I want Magni to actually go around the room and detect objects with the camera , instead of just rotating around on the same spot…)
thanks
Hello,
Any thoughts?
thanks
