The device was built by Doctor Ovi Kintobor, which is Ivo Robotnik's name spelled backwards, and resembles a giant treadmill. Sonic used the machine to learn how to run faster (although even before this he was the fastest hedgehog on Mobius), in exchange for using this speed to help Kintobor find the missing seventh Chaos Emerald for his Retro-Orbital Chaos Compressor.
