One of my tasks in my workplace is to measure the UX efficiency of our product (collaborative robots) and one of my main challenges is to figure out how to measure the customer experience when interacting with the robot. (You can control the robot through a UI on a tablet or by manually grabbing the robot and moving him.)
The challenge with this is that, although I can analyse how the user performs when interacting with the UI on the tablet, I can't measure how the user deals with the robot himself. (Problems might arise because the robot is heavy, hard to move, etc.)
We conduct field visits to customers but I'm looking for methods that are more scalable and able to be done remotely, if possible.
