KO - To understand how to use VEXcode VR to program a robot to move and turn using block-based code.

All: Will be able to identify and use basic movement blocks in VEX VR.

Most: Will be able to combine blocks to create simple movement sequences (e.g. an L-shape).

Some: Will be able to apply loops to make efficient code (e.g. programming a square path).

What links robots to programming?

Vex VR - What is it

Think or a scratch interface but to control a sensor driven robot

You can view the robot in various ways to see its behaviour based on your code.

You will code it to solve tasks

SPLIT SCREEN VIDEO TUTORIALS

• Arrange your screen in split view:
• Left: YouTube video tutorial
• Right: VEXcode VR editor (open: vr.vex.com)
• You’ll follow each video step-by-step while building your code.

Tutorial 1: Play & Practice

• Complete the first video - click here
• If you complete the first video, you can move on to the second video.

What does the “drive forward” block do?

Tutorial 2: Play & Practice

• Complete the second video - click here
• If you complete the first video, you can move on to the third video.

Which new block did you use this time, and what does it do?

Tutorial 3: Play & Practice

• Complete the forth video - click here
• If you complete the first video, you can move on to the fifth video.

How would a loop make your code shorter or more efficient?

How could you adapt your code to draw a rectangle instead of a square?

What did you find most challenging today?
