Using Ringo’s Navigation
Ringo has two incredible sensors that can be used to sense
his motion. The first sensor is called an Accelerometer. An
Accelerometer senses movement in front-back, left-right, and up-
down motion. It can be used to determine how far Ringo moves. The
second sensor is called a Gyroscope. A Gyroscope senses rotational movement.
For example, if you keep Ringo in the same location but you rotate him in a turn,
the Gyroscope can be used to determine how many degrees he has rotated.
Taken together, these sensors embody an “inertial navigation” system, where Ringo
can determine how far he has moved and how his orientation is changing. You
could for example, make a 45 degree turn and move forward 1 meter. Awesome!
This is the first “Skill Level 2” lesson. We’ll get a bit more advanced in the
discussion here but have no fear - the actual functions used to move Ringo are
fairly straightforward.
