The explanation of the code is as follows:
The program starts when the when started block is triggered.

The robot’s drive and turn velocity is set to 100% for full speed.
A while loop runs until the Down Eye sensor detects red beneath the robot and checks the distance:

• If the distance is greater than 200 mm, it drives 250 mm forward, then turns right by 90°.
• If the distance is less than 200 mm, it turns left by 90° to find a clear path.

Once red is detected, the loop ends and the robot stops.

1. Control blocks let you decide when and how often the robot acts.

2. Distance sensing blocks use the robot’s distance sensor to measure the space
between the robot and obstacles.

USING MAGNET BLOCKS

Magnet blocks allow the virtual robot to pick up and drop magnetic disks using its built-in
electromagnet. These blocks are essential for simulations where the robot interacts with objects
like coloured disks.

energize Magnet to boost

The Magnet Block in VEXcode VR has two settings:
Boost: This increases the magnet’s strength so the robot can pick up multiple disks at once. It
is useful when you need to collect a group of disks quickly.

Drop: This lowers the strength of the magnet so it can release the disks it is carrying. The robot
drops them at the desired location (like a goal zone).

Program 7 Prepare a disk mover program.

The robot’s task is to locate, pick up and sort coloured disks on the Disk Mover playground.
Using its electromagnet and sensor logic, it must identify each disk’s colour and transport it to

the corresponding drop zone.
