MAZE
this first picture is the part of the robot that makes the stair climber go up the stairs. with a system of gears and help with the tank tracks it helps the back set of tire lift the rest of the robot then you slowly drive forward landing on your designated platform then the tracks retract and the robot repeats that system
this is what is left from the chassis of the stair climber. This chassis was a pain to build considering i never took into account on how would this robot turn when needed with only one engine. so after a long rampage of taking the robot that took 5 classes to build this is what is left.
this is the stair climber that i had built for this maze. i didn't take a picture of mine while it was finished being built before i took most of it apart then realized i forgot a picture. so this is a picture from Google images on the ev3 stair climber.
