I am studying Quick Start-Kaya in isaac SIM Document.
First we tested the joystick application. But I don’t know if I need to connect the joystick to the host or the jetson nano. Also, when I turn on the isaac SIM, the kaya robot does not appear on the screen when I press play and nothing happens.
Second, we tested the Object Detection application. I have a question, is it right to run isaac SIM in one terminal and “bazel run apps / kaya / unreal_sim: object_detection” in the other terminal? I got an error when I did like above.
The error is this:
