Introduction To Ozobots
Hello Robotic Engineers!
Our Learning Targets are:
(Innovative Designer 4.b. and CCSS.Math.Practice.MP1)
I can program a robot to use visual codes to navigate paths and arrive at a finish point.
I can collaborate with my group to make sense of problems and persevere in solving them.

Introducing the Ozobot bit!
Ozobot is a smart robot (the smallest of its kind) that can follow lines or roam around freely, detect colors, and can be programmed using visual codes. Over the next few classes, you will learn hands-on about robotics, math and programming from these little guys.
Tiny Robot, Big Possibilities!
What makes this little guy tick?
Can you find: the on/off button, micro-USB port, wheels, skin, circuitboard?

Programming Ozobot With Markers
Ozobot is a robot you can code! For todays's task, we will be learning one way to program Ozobot: using markers and paper. Turn the Ozobot over. On the bottom, you can see 5 openings (BIT) or 8 (EVO) with lights shining out of them. An optical sensor lives in each of these openings. These sensors are Ozobot’s “eyes.” Each of the sensors sees how bright the paper underneath is. This way, Ozobot can differentiate the black and white parts of the paper to know where the line is! |

First ALWAYS Calibrate:
What does this mean? Ozobot’s “eyes” (the sensors) are very sensitive to the surrounding light. So much so that, if the paper changes or if you go closer to the window, it affects how Ozobot sees what’s underneath. To let Ozobot know what his surroundings are, you need to calibrate:
On paper:
- Press and hold the ON/OFF button until Ozobot blinks white.
- Place Ozobot on the black dot on the plastic calibration zone card that came with your packaging (If you are playing with markers on white paper, you can also draw a 1 1/2 inch solid dot with a black sharpie and place Ozobot at the center
of it to calibrate). - When Ozobot blinks green, it means that it has successfully calibrated. Start
over if Ozobot blinks red.
