3.2. How do you move straight?

STEP 1: Green Block Tab, Click and hold Move Steering and drag to programming area

STEP 2: Drop next to the Start Block (green arrow) (See animation)

Challenge 1 Move straight 3 seconds

Hint: Turns

DISCUSSION

Did you guess and check a lot?
Yes. Programming with seconds, rotations and degrees using guess and check takes a lot of time and effort.

Did changing the speed matter?
Yes. When you move in seconds your speed will matter.

Do you think the wheel size will matter? Why?
Wheel size affects degrees/rotations.

Do you this the battery level will matter? Why?
When you move in seconds, battery levels change the power.
