Motorola has been working on Moto Mods and Moto Z for more than two years, and the company now explains some of the processes that took place behind the scenes. Building a phone that had good battery life and was more durable and thinner than previous phones was quite a task for the company to conquer. Between developing a liquid cooling system and using aircraft-grade stainless steel, Motorola was able to keep the phone super thin while not compromising on quality.

Moto Z and Moto Mods

From Motorola's post:

Up until now, your smartphone experience has been limited by your phone's hardware and software capabilities. When it came to developing Moto Mods, we set out to remove those barriers by creating a phone that changes as your needs change, and does so in a truly seamless way. For example, we wanted to make sure the process for swapping out Moto Mods was as fluid and natural as possible. Our solution: very strong magnets and an automatic connection process that doesn't require additional steps or rebooting.

It doesn't end with Motorola though. The company has opened up its Moto Mods Developer Program so that developers will be able to create their own Mods for the phone. To make it even easier to get started, Motorola is offering the same hardware and software development kit it uses internally with those who are interested.
