* Each wing is 9 cms high and 3 cms wide
* The body is 5 cms high and 4 cms wide
* The neck is 1 cm long
* Each side of the head is 2 cms
There are multiple ways this can be achieved with the Pro-Bot and the code below is only one way.
Starting at the top left corner of the left wing and facing right, the following code can be used:
