How to dock a cart on my rocket?

[brienne]

Hey,

I installed Ant Bobcat rover. I try to stick one on my rocket with 2 docking points.

But i can't decouple. I managed once^^. But now I can't do it anymore.

What did I miss plz?

I'd like to "stick" a rover on my rocket and release it on Mun,..

Can you leave images? If you dock to the sides, your center of mass will move, and you will flip over in your flight.

I try with this vessel, on launchpad.

Ports were upside down^^

Here, that works.

Unless you plan to dock it back on there later (and I can't see how you could) you don't actually need the docking port on the rover. The "base" port on your lander will hold the rover in place like a decoupler, until you release it.
