Maqueen Robot Plus V2 Issues – Moving Off Course and Line-Following Problems

Hello DFRobot community,

I recently purchased the Maqueen Robot Plus V2 along with a mechanic set, and I'm encountering some issues that I need help with.

Direction Issue: When I try to move the robot forward, it consistently veers to the right rather than moving in a straight line. I've tested this on multiple surfaces, including wooden and concrete floors, but the problem still occurs.

Line-Following Issue: I'm also having trouble getting the robot to properly follow a line. It appears that the line-following sensors aren't working as expected.

I'm using two micro:bits for control—one as a receiver on the robot and the other as a remote transmitter. Here are the links to the code I'm using:

Maqueen V2 Receiver Code: https://makecode.microbit.org/S39027-28347-49765-53251

Micro:bit Transmitter Code: https://makecode.microbit.org/S74058-50347-30808-45685

Line-Following Code: https://makecode.microbit.org/S69265-20327-97719-04054 

I'm teaching my son robotics, and I need a properly functioning unit for this. Has anyone else faced a similar issue, or does anyone have suggestions on how to fix these problems? I would appreciate any help or insights you could provide.

Thank you so much for your assistance!

Best,
Hasan
