Detect when a spidertron is stuck orbiting around a waypoint and set it free again.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
Transportation of the player, be it vehicles or teleporters.
So, what is a spidertron's orbital velocity?
The higher the velocity the easier it is to get them to orbit but I've seen spidertrons with just vanilla exoskeletons orbit so I'd say the orbital velocity is lower than you might expect.
