Hi everyone!

I created a small programming challenge using Open Roberta Lab, a block-based environment often used to teach coding logic through virtual robots.

🧩 The Challenge

The goal is to program a LEGO EV3 robot simulation to follow the exact same path shown on the challenge mat below.

It includes:
• straight segments
• precise turns
• orientation changes
• smooth trajectory matching

The main task is:
How would you code the movement logic?
Would you break it into steps? Use loops? A small state machine? Maybe proportional control?

💬 Discussion

I’m genuinely curious:

• How would you structure the logic for this path?
• Would you use motor rotations?
• Timed movements?
• Sensors?
• Or a hybrid approach?

I’m collecting different strategies from programmers with different backgrounds — beginners and experts are all welcome!
