11. Think Blocks
You’ve met the Battery block, and the black
Sense blocks and the clear Action blocks. It’s
time to meet the colored Think blocks. Think
blocks are the colored blocks.
Because Robots are machines that sense
first, then think, then act, we need to be
sure Think blocks are placed between the
Sense block and the Action block you want to
impact.
In addition to the green Passive block, the
simplest Think block is the red Inverse Think
block.
12. The Inverse Think Block
To make a Nightbot light up when it’s in a dark
place, you need a Red Inverse block. Ooops!
This robot as pictured is wrong. Can you figure
out why?
Let’s go back to the Light-sensitive Dimbot. It
has a Brightness Sense block and a Flashlight
Action block. (It also has a Battery block, of
course, but we’re going to stop mentioning the
Battery block because every robot has one.)
The Dimbot made a silly flashlight. Its lamp
is bright when it’s in a bright room, and
dark when it’s in a dark room. We’d prefer a
flashlight robot that turns on when it’s dark,
and turns off when it’s light. That’s why we
need the red Inverse Think block.
