Set Effort appears only to allow a number value not a calculated one used in the example.

What problem are you seeing. I just tried it and it works, other than a speed of 0.25 was too slow for my motors to move the XRP. I needed a speed of 0.4 for it to start moving.

Thanks for your help on this. I was trying to use a Logic block rather than a Math block! Now sorted.

More on the ‘line follower’ Blockly code…

I discovered that the example Blockly code did not generate Python code similar to the example shown, so I reverse engineered and created Blockly code that does work and generates similar code to the Python example.
