Introduction: K'nex Roller Coaster: Twisted Steel
Twisted Steel is a K'nex roller coaster, automated with LEGO EV3 Mindstorms. It was built over the course of several months. It features three inversions: A loop, heartline roll, and a corkscrew. It has a lift, and brake run, complete with catwalks. The station is fully automated, with station gates that open and close.This was my first roller coaster with tube supports.
