Pybricks line follower with blocks

[Mixel8te]

We've decided to change over to Pybricks from Lego Spike native platform for coding this year. We're busy practicing for the WRO competition later this year and we're struggling to recreate the line follower in Pybricks. He hasn't started Python yet, and there won't be enough time to do so before the competition, so he needs to find a way of doing it with blocks in Pybricks. Has anybody been able to recreate a line follower using blocks in Pybricks similar to how it is done in the Lego Spike environment?

Could you show the line follower you are referring to in the Lego Spike environment?
Are you looking for ...?

• very simple
• proportional
• PD
• PID

For proportional line following you can take a look at my videos (in German, but the English subtitles are in good quality)

  and the other "Linienfolger" Videos in the playlist https://www.youtube.com/playlist?list=PLWjRXCPcSmsagrhqYhH4oNo5CCE4cEmrY

Hi Gregor They were looking for a proportional line follower, and apparently one of your videos worked perfectly for them. They couldn’t get the subtitles to work but they paused the video and duplicated your blocks, even gave them the German names as well! I can’t thank you enough for the help. It’s amazing how much more accurate you can get your robot using Pybricks vs Lego Spike.
