“Non rigid devices which extend beyond the frame of a robot, are typically considered to be risks of entanglement. These types of situation are evaluated on a case by case basis. Specifically, non rigid devices which drag along the tiles, beyond the frame of the robot, will definitely be considered unnecessary risks of entanglement.”
The device which is linking the two sections of the robot appears to be a non rigid device, dragging along the tiles and beyond the frame of the robot.
Please note, the reason I’m using the phrase “appears to be” is because it’s impossible for us to make a certain determination based on a short video clip.
