Letters E and I

Today we will be working through lesson 2: Letters E and I.

2.)

I know what a robot is and why we have them.

I understand that robots use sensors to "see" the world.

I can program a robot to use a sensor to drive itself around a track.

Today we will be learning about sensors on robots. We will learn about how these sensors help robots to "see" their environment and respond to it in various ways. We will be looking at a toy dog robot and its sensors and then we will be looking at an Edison robot that we will program to follow the track.

EdFact

Edison’s line tracking sensor shines light on the surface and then measures the amount of light that is reflected back. White reflects a lot of light, giving a high light reading and black reflects very little, giving a low light reading.
To track the line Edison is in a constant state of dissatisfaction. When he is off the line, he turns right to get on the line. But when he’s on the line, he turns left to get off the line. This results in him waddling on the edge of the line.
