● Turning and Navigation: After each pickup and drop cycle, the program checks if the count is
less than 3. If true, the robot turns right by 90 degrees, drives forward 800 mm, then turns left by
90 degrees. The variable count increases by 1, allowing the robot to track which stage it is on.

Program the VR Robot in VEXcode to navigate around obstacles to reach a goal. Use sensor checks
and turns to avoid obstacles and complete the path.

T ¢ Robot velocity: The speed you set for the robot so it knows how fast to move.
E
R ¢ Loop: A bit of code that repeats the same set of instructions again and again.
M
S ¢ Sensor: A small device that collects information (like distance or colour) for the robot.

REWIND RUN

« Virtual robots are computer-simulated robots that you can program and control on a digital platform
or your computer screen.

« VEXcode VR is an online platform that allows you to learn robotics and programming using virtual
robots, without requiring any physical hardware.
« In VEXcode VR, the Drivetrain blocks are used to control the movement of the robot.
« Drawing blocks allow drawing paths on the playground by controlling the robot’s movement.
« Eye-sensing blocks help the robot use its eye sensors to interact with its environment visually.
« Distance sensing blocks use the distance sensor to measure the space between the robot and obstacles.

« Magnet blocks allow the virtual robot to pick up and drop magnetic disks using its built-in electromagnet.
