How to make rover animate uphill

Hi everyone, firstly I’m quite new to all this, so sorry if this is a simple question. I’m doing a animation sequence with a space rover and want to it react accoringly to the terrain. At the moment if it encounters any elevation differences (bumps, hills etc), the rover will pass straight through them. How do I make it so my rover is fixed to the landscape and therefore moves relevant to it? Many thanks

Here’s a tutorial:

Hope it helps! :innocent:
