Develop&Plan

sketches

#1

I made sketches about each part and scales I will follow.

  • uses used bottle caps for wheels
  • it uses wooden sticks for the body and straws to let the wheel spin inside.

#2

After making a prototype with my first sketch, I found out the wheels have too little friction, and the body is unstable.

  • wrapped rubberband to all the wheels to increase friction
  • Add one more stick to the main body to increase stability and prevent it from breaking.

 

#3

after making more prototypes, I learned it works fine but is too slow and doesn’t go far.

  • I decided to change the rear wheel into a bigger wheel from the school’s design area. (considering the ratio of wheels).

Making sure everything was ok, I moved on to Create&Improve.
