The Transporter Machine, also called the VMU Machine, Chao Machine or Chao Transporter, is a machine that appears in the original Sonic Adventure and Sonic Adventure 2. It was later succeeded/replaced by another device.
The Transporter Machine is located exclusively in each of the respective game's Chao Gardens. To activate it, the player has to push the red button on the foot of the machine. Should the player be carrying a Chao when it is activated, it allows the player to deposit their Chao within the Dreamcast VMU so they can take their Chao with them.
The Transporter Machine appeared for the first time in the original Sonic Adventure. When used, all the player has to do is choose which available slot in the VMU the Chao must be deposited in.
When transferred onto the VMU, the Chao will take part in Chao Adventure, a VMU game where players can look after their Chao and observe their travels.
Sonic Adventure 2
In Sonic Adventure 2, the Transporter Machine was renamed Chao Transporter. Otherwise, they function in the same way as before. It is even possible to transfer Chao from Sonic Adventure to the new Chao Gardens available in Chao World.
When transferred onto the VMU, the Chao will take part in Chao Adventure 2, a VMU game where players can look after their Chao and observe their travels.
