7. (1) Smart Robot Arm
Use Kinect (3-range sensor) to help a robot arm to find objects
A 3D range sensor
from Microsoft

8. Smart Robot Arm
Kinect
Microsoft’s Kinect (a 3D range sensor from Microsoft) can capture RGB image and depth image in ~25fps.
Then use the information to control the robot arm
RGB image and depth image
Reference:

9. Smart Robot Arm
Using computer vision methods to find the 3D position of the box.
Send the control signals to the motor driver
Put the box near the RFID reader
Read the ID

10. (2) Intelligent Voting Machine
Overview:
To develop a voting machine for elections.

11. Intelligent Voting Machine
Smart Card Reader
Atom
Fingerprint Reader
Interface

12. Intelligent Voting Machine
Read ID card
Check the password with the DB
Read fingerprint from scanner
Match the fingerprint with the records in DB
Do face register/recognition
Get vote from pad and send to DB

13. (3) Intelligent Restaurant System
Overview:
To automate customer ordering of food in restaurants

14. Intelligent Restaurant System
Dot matrix display to
show ticket number
Using Atom to show the
ordered item of table 1
Waiting ticket with number and barcode
Barcode Reader

15. Intelligent Restaurant System
Three atom boards are connected through LAN.
Print tickets for customers
Show the ticket number that is ready
Scan barcode on the ticket
Customer can order the dishes and check the progress of the order using the touch screen in real time.
In the kitchen, cooks can update the status of the dishes.

16. Other Potential Porjects
Human Tracking Robot with Kinect
Register and follow target face
Find the depth map of the environment
Avoid obstacle
Track target human without seeing the face
Embedded computer vision system development using OPENCV.
Application:
Helping disabled people to control the shopping cart

17. Acknowledge
Thanks for the support from Intel and their donating of 10 embedded systems to CUHK.
