Rail drone
Rail drones are puzzle elements in The Talos Principle 2. They move (along a predetermined path drawn as a white line on the ground) only when activated by a laser of the correct color. They can pass through purple barriers but not blue doors.
The distance from the ground to the top of the platform is similar to the height of a hexahedron. In particular, the player can jump from the ground to the top of a platform or place an object (for example, a connector) on a platform. Also similar to hexahedrons, they will stay at a fixed position in the air when over an active fan.
