Sample Darwin Tutorial Walkthrough

In Darwin, there are many in-built tutorials that will guide you through the basics of various functions. I will go through only some of them.

Get to the “head_tracking” folder in the directory darwin→Linux→project→tutorial→head_tracking.

$ cd /darwin/Linux/project/tutorial/head_tracking
$ sudo su
# make
# ./head_tracking

The command make creates compiles the head_tracking.cpp that is already in the folder and produces the executable file that can be run by keying ./head_tracking.

Colour of the item tracked by the Darwin can be calibrated as such.

• Open a firefox browser.
• Type in the correct IP address in the address bar.
• Change the ball hue to dictate the colour of the item you want Darwin to track.
  • 60 - Yellow
  • 170 - Green
  • 210 - Blue
• The object that bears the colour is tracked will be shaded in red in the feed from the camera.
• There are other options to play around with to further narrow down the range of hue that Darwin will recognize.

Get to the “ball_following” folder in the directory darwin→Linux→project→tutorial→ball_following.

# cd /darwin/Linux/project/tutorial/ball_following
# make
# ./ball_following
