And you couldn’t have that special day the way your friends do – you know, wear the ring on your finger and have it mean the same thing as everybody else. Just put yourself in that person’s shoes. It makes me feel sick to my stomach …. When I shared a picture of my tattoo on my Twitter page and said, ‘ALL LOVE is equal,’ a lot of people mocked me – they said, ‘What happened to you? You used to be a Christian girl!’ And I said, ‘Well, if you were a true Christian, you would have your facts straight. Christianity is about love.’ The debate resulted in a lot of threats and hate mail to people who agreed and disagreed with me. At one point I had to say, ‘Dude, everyone lay off.’ Can’t people have friendly debates about sensitive topics without it turning into unnecessary threats?” - Pop star Miley Cyrus on her marriage equality tattoo - - - - - - - - - - -

Qbo The Robot Sees Its Own Reflection and Recognizes It

Meet Qbo, the robot.  Created by Francisco Paz, Qbo is able to use recognition software in conjunction with pre-programmed responses to recognize its own image.

In the video below, the lime-green Qbo transits to the "Object Recognition" state from its internal state machine, to learn to recognize its mirror image, as if it were a regular object. Technically, how does Qbo do it?


According to it's YouTube Description:
The "Object Recognition" state is implemented to execute simultaneously different ROS nodes: one responsible for the head and base movement; another to select an object from the image using the stereoscopic vision; another to recognize objects or learn new ones. The object recognition algorithm uses "SURF" descriptors and the "Bags of Words" approach (through the OpenCV library), and stores images in Qbo's internal storage system.

Qbo has several stored answers and behaviors in an internal knowledge base, that we upgrade as the projects evolves, to make questions or orders to Qbo such as "What it this? or "Do this". Qbo interprets the object "Myself" as a an ordinary object, for which it has special answers in its internal knowledge base such as "Woah. I'm learning myself" or "Oh. This is me. Nice". Qbo selects its reflection in the mirror in the image that he sees using the stereoscopic vision, and one of our engineers interacts (speaks) to him so that Qbo can learn to recognize himself as another object. For direct interaction, Qbo uses the open-source software Julius for speech recognition (in the video, you see how Qbo receives the order to turn around, and he responds to it by moving its base 90 degrees), and Festival for voice synthesis.

It's cute, yet kinda creepy. Data's great great great grandfather. It's so technologically advanced and probably costs millions to make. So what's the best idea ever?!! Place robo on a much wider table.

I have organized my blogs with 3 days worth of postings, so if you wish to continue reading the days before that, and so forth and so forth, you can click the "Older Posts" button /\ /\ /\ right /\ up there.
