Navigating around obstacles is a key to success on the robotics competition field.
Can you list all the movements you think your Driving Base should be able do?
Build a Practice Driving Base.

This is a simple but effective way to learn some field tactics:
- A Practice Driving Base
If you have time, build your own design.
Try these programming stacks one after the other.

What do you see?
Change the values of each block’s parameters and see what happens.
Make your Driving Base move in a square.

Pick actions from the stacks that are already on the Programming Canvas.
Use a repeat Loop in your program.
What action do you need to repeat to make your Driving Base to move in a square?
Here’s an example:
Time for a field tactics challenge!

Place 8 colored bricks on a surface and use your programming skills to cross the “field” without touching the bricks.
Develop your programming skills by writing the pseudocode first.
For example:
- Move forward to "this point"
- Turn of about 45 degrees
- Move backward "a little"
This list is called pseudocode.
How did you do?

Think about what you did well and what you could’ve done better.
Great start on avoiding obstacles!
