The picture above left is a
zoomed-out in-game top view of
the rst challenge, Collect the
Blue Gem.
Look at the grid map (upper right)
and compare it to the distance
key. The distance key says that
a grid square is 100 cm wide and
100 cm high. From the robot to
the blue gem is conveniently one
grid or 100 cm.
The example robot is Anemobot (the submarine model). Its specications tell us that it
has a 10 centimeter wheel diameter. With this information we can nd the circumference
of the wheel and then how many rotations it will take to move the 100 centimeter
distance. See the calculations below:
100 cm distance
31.4 cm circumference
= 3.18 wheel rotations
Anemobot will have to travel 3.18 wheel rotations to
move from the start point to the blue gem!
