Macro MOCO shooting inside a pinball machine

how do you shoot inside a working pinball machine?
This months challenge was how do I film at eye level of a few mm off the ground inside a working pinball machine whilst still doing dolly moves and tracks? Well the idea I had was build a robotic rig and shoot 90 degree probe lens shots, simple!

I had some custom mirrors and prisms built and ran the rig though Dragonframe to get repeatable precision moves.
