Please note that these are grips for RS wheels, not RC wheels. For wider wheels, you'll need to look for "Power Räder C-Modell", which are not available from galaxus.

I have exactly the same problem and I'm trying to do the same thing as you. Have you found the solution? Wider wheels with grippers?

According to our research, these robogrips (https://www.galaxus.ch/fr/s4/product/robomow-robogrips-pousseurs-tondeuse-automatique-machines-de-jardinage-accessoires-8295082) are compatible with the RC robot C-wheels (RC MRK7012A). The above drive wheels are not compatible with your model, as they are designed for the RS range.
