The presentation made it sound a bit more intricate. At least watching the presentation, to me it seemed like the system is:
1. A couple dozen guests enter individual ride pods of two.
2. This group of pods is then dispatched onto the "ride track", essentially just a outer loop encircling an inner loop of Kuka arms.
3. The pods spin around the track for a short period of time till they reach and attach with their corresponding Kuka Arm. While spinning, you receive a randomized mission briefing themed around a Marvel character, specifically how your test flight will attempt to emulate the movement and style of that films, which presumably has more unexpected movements.
