positions, that will be useful to develop different games.
The camera is placed in a position on top of a mounted-on aluminum
bar that allows us to have the best depth of field by increasing the field
of view. The idea is to detect objects and visualize the environment between
the boundary of the robot to all the way in the ground and up to
2 meters in height, which allows also to see faces of people or the objects
not on the ground. Mechanically, the camera itself is connected to a servo
that enables the camera head to move freely in 120 ◦ in the vertical axis, as
shown in Figure 3.9 and 3.10. This configuration gives us the flexibility to
generate different types of games using the vision available in a wide angle
and interchangeable height.

The last mechanical component is the collision detection mechanism, to
avoid obstacles in the environment. There are lots of good solutions to this
issue. By using different types of sensors such as sonars, photo resistors,
