Pepper 机器人一直显示相同的图像

Question

I am programing a pepper robot with choregraphe and when I show and image and try to show another image in the same behavior or a different behavior it shows the same image. Does anyone know how to actually show the image I want?

Answer 1

this is from a different thread, I cant find it again but make sure your show image box looks like this (look at the bottom for additional code)

def onLoad(self):
    pass

def onUnload(self):
    pass

    tabletService = None
