The objective of the competition
was to develop a robot that could recognize different objects and take them
to predetermined locations.
Kambiz-Dana won the second prize of part two of The 2nd Iranian Robot
Contest, University of Tehran, 2001.
Robot Technical Feature:
This robot utilized computer vision
to recognize the objects in the pitch which were:
1. Yellow tennis balls
2. Red soap boxes
3. Black cans
The robot had a tank which provided four empty spaces and made it capable to
carry four objects simultaneously and consequently expedited the gathering
algorithm. There was special mechanism in front of robot for catching 4
objects and take them to their relative location which you can see in
picture.
Using a camera which was attached
on the head of the robot, it recognized each object according to its
relative color.
The robot could fine his way by the same algorithm that Little Kambiz used.
It took a picture and found the optimum object to pick up, identifying its
identity and position. Then it went toward the object, picked it up and kept
it inside itself.
The robot had a programmed
microcontroller inside which controlled it low level task and received the
high level command from PC through serial port.
Using a very precise feedback for each wheel in addition to eight infra-red
sensors, the robot could follow the path accurately.
