The Cart Assembler can attach a structure to carts that pass through it when supplied with a redstone signal.

Configuration

Using a Wrench, the Cart Assembler can be configured to set the movement of cart contraptions to "Always face toward motion (default,)" "Pause actors while rotating," and "Lock Rotation." On the second setting, actors such as a Deployer will not work while the cart rotates. On the third setting, the contraption will not change alignment along with the cart, and will retain the same rotation from when it was built, much like the effect of a Mechanical Bearing on a cart contraption.

Cart Contraptions

Single Cart contraptions as well as Carriage contraptions can carry items, liquids, or mobs, provided they have a storage block, Fluid Tank, or Seats, respectively. Cart Contraptions can also carry mobs or items using only their collision.

Cart Contraptions can be taken into the inventory by right clicking them with a Wrench. Excluding entities, this keeps all storage and cart configuration.

Similarly to rotating structures, having a Mechanical Bearing in the structure will cause the attached part to keep the same alignment as the cart moves.

Cart Contraptions can use the Deployer, the Portable Storage Interface, or the Mechanical Saw, Drill, Harvester or Plough to interact with the world.

Cart Contraptions with a Furnace Minecart can automatically take Coal as fuel from onboard inventories.

Despite having collision with mobs or items, Cart Contraptions do not collide with blocks unless the appropriate world-interaction block makes the collision.

Carriage Contraptions

Carriage contraptions are moving structures connected directly to two minecarts.

Carriage Contraptions can be made by connecting two Cart Assemblers with minecarts using a structure. This will not work if the two minecarts are linked together by Minecart Coupling.

Carriage contraptions can also be disassembled by right clicking with a Wrench.

Aside from movement, there is no difference between the functions of a Carriage Contraption and a Single Cart Contraption. However, the smoother movement is better for moving mobs or items with only collision.
