how to rig ,this character?
so i modeled the megabot from big hero 6 ,but have a hard time rigging , cause i am a beginner .
i want to rig it without the moving of the body like a ball , should i do it with shape keys .pls recommend some videos as well since most of the videos are like do this do that but never fully explain everything ,they just instruct us .
big thanks for the response
