1: All parts started out with a few mere sketches that were later designed and given proper dimensions in a computer generated animation in an open source program called blender. As you can see in the (blueprint) pictures, I first designed 3d meshes from scratch and rendered them in 2d to achieve the blueprint effect. After creating the pieces, I created an animation on how all of the parts came together
2: Dealing with the mechanical problems was the biggest set back. Due to lack of support, one of the sides of the old track system was going off balance, so I created a brand new (better) type of track system.
3: Creating and assembling was perhaps the simplest task. Since I had my designs ready, all parts came together very well. My controller called EZ-robot bluetooth controller, greatly aiding in programming the parts. In the end, I was able to wirelessly control the servos and sensors with a joystick connected to my laptop. (sensors include a speaker, LEDs, and switches) (moving servos acted as a switch to power the track's movement and direction)

p.p.s there is also a website I created (from scratch) which gives more information on this project ---- PROJECT WALL-E
