Almost every butterfly I see bobs up and down while they fly. Do they have the same fluid system for balance that we do? How do they navigate the world and what is their system for balance?

As people said above, butterflies do not have an inner ear so they would not experience dizziness as we would.
As to how they navigate the world, they are very visually oriented animals and mainly use their eyes to stabilise their flight.
Some can even use the polarisation pattern in the sky to navigate. Polarised light is light that is “aligned” in a specific direction, and naturally in the sky there is a pattern of polarisation due to how sunlight interacts with the atmosphere.
They would use their antennae and smell to find the right tree to lay eggs on or to find food, but orientation and stabilisation is visual.
