Reflection

Strength

  • Stable and strong

Since the main material used is lego, the car is stable and relatively strong: the shape doesn’t change unless an extreme force is exerted.

  • Functioning elements

Even though the car itself is not functional, all the elements on top of it are functioning: the batter, switch, and motor. If the wires were fixed, these three components would be correspondingly functioning.

  • Well-made base

The base, which is the bottom part, is well-made; it is efficient in material, with using only a few pieces.

  • Recyclable materials

 

Needs Improvement

  • Weak connection of wires

To connect the wires, a teacher helped me by using a soldering iron to instantly melt the metal edges. However, the connections were fragile; the wires snapped several times. I fixed it by asking the teacher to connect them once more, but it fell apart again.  To solve this problem, I could have come up with other ways and tools to connect the wires, but unfortunately, I didn’t have enough time.

  • Making a lego-base

Creating the base of the car with legos took me a long time; I struggled especially with how to fix the wheels underneath the legos so that they are stable. Originally, I planned to attach the wheels directly to the lego, however, I realized that it wouldn’t move the wheels separately. Thus, I used the lego pieces to create a part where it could store the metal connector of the wheels inside. (where the red arrow is pointing in picture 2)

 

Feedbacks from classmates 

  • It is a very cool idea.
  • If the wires didn’t fall off, it would be pretty cool.
  • Cool idea! Something to think about: If you had more time, what would you change?
  • The product is super neat and cool! The original is also great maybe the proportions could have been more accurate.
