©SIProp Project, 2006-2008 4 Agenda Summary Part “Software” Detect the face Calculate the course Calculate the distance Part “Hardware” How to control the robot How to process the analog data Need more power supply
©SIProp Project, 2006-2008 5 Summary This product is "Auto Chasing Turtle". By autonomous control, this robot recognizes people's face and approaches to the detected human.
©SIProp Project, 2006-2008 6 Robot behavior 1.Rotate and look for the human who becomes a target. 2.Detect the human with recognizing people's face by using RGB camera of Kinect. 3.If it can detect the human, it calculates the course which it should follow. And It direction is changed. 4.Calculate the distance to target by using Z(depth) camera of Kinect. 5.Walk toward to target. 6.2-5 are repeated until it becomes a suitable distance. And if losts target, returns to 1. 7.The scene that it is working in real time can be seen by iPad.

©SIProp Project, 2006-2008 21 Analyze KINECT data Detect the Face Calculate the course Calculate the distance 1. detect 2. course 3. distance
©SIProp Project, 2006-2008 22 Detect the face What’s data ? 640x480 RGB image, using KINECT’s camera, Characteristics of human face. KINECT Image
©SIProp Project, 2006-2008 23 Detect the face Face recognition Characteristics of human face Statistical face detection and machine learning.
©SIProp Project, 2006-2008 24 Detect the face Not all frame, but realtime analyzing. Auto search around people. Chase specified human.
©SIProp Project, 2006-2008 25 Calculate the course Using width. 1.Specify center position of face. 2.Specify position of the face in 4-sections relavive to KINECT’s image.
©SIProp Project, 2006-2008 26 Calculate the course Using height. Change Kinect’s angle. Specify position of the face in image relavive to KINECT’s image.
©SIProp Project, 2006-2008 27 Calculate the distance 1.Mesure the depth of specified point using KINECT. 2.Robots walk forward or back, depending on the mesured distance.
©SIProp Project, 2006-2008 28 Performance problem Data analyze and image processing Face recognition More resource !! GPU, Multi core.

©SIProp Project, 2006-2008 31 How to control the robot? Only control servos’ angle. Accuracy Reaction velocity Torque Compact(Size, Weight)
©SIProp Project, 2006-2008 32 How to control a servo? RCB series 24 controls pins Control commands Control all servo at same time !
©SIProp Project, 2006-2008 33 More control Do you know this IC?
©SIProp Project, 2006-2008 34 How to process more sensors? Analog data is stream data! Need powerful processor Need to save power for Mobile Now Solution ARM base Processor dual Cortex A9 MALI 400 GPU Next trend GPGPU FPGA
©SIProp Project, 2006-2008 35 How to optimize for each sensors? http://linaro.org/ Mission Optimize for each SoC & Platform We are committer!
©SIProp Project, 2006-2008 36 Trouble: Need more power supply Don’t run beagleboard-xM by 5V/1A power supply. It needs 5V/2A. Standard USB battery has 5V/1A. Create power supply by myself My battery has 12V/2A. My plan is to create convertor of 12V/2A ⇒ 5V/2A. Can’t get power IC… Using car’s cigarette adapter which convert to USB. 12V ・ 24V/2A ⇒ 5V/2A
