While the mechanism of the product works, it doesn’t work for its purpose. The main problem is that any type of string or rope inserted through the wheels stops the motors, meaning the resistance is too low. Sadly, it is a problem I can’t fix as it is a problem with the materials given and used, and not the mechanism itself. However, I am quite proud of the circuitry and base we’ve successfully made throughout this project, and if it were to work then we would be done after inserting a string and adding the final directory part. I would improve the materials we use and ensure that it works with the string prior to building, and also use parts that were meant to be together, as the skewer we had to use due to the wheels being too large caused the wheel to spin slightly slanted. This project is quite environmentally friendly as we mainly used wood for the base, which could be reused if needed. The potential customer if the product had worked would have been fascinated with the capabilities of the product, and could even learn physics from it after searching up the scientific concepts involved online. Our product could be used to create future scientists and help spark their interest in different scientific toys. Finally, our product met the criteria as even if the purpose didn’t work, the mechanism converted chemical energy stored in the batteries to electrical energy to mechanical energy that made the wheels spin, the wheels spinning also create sound and thermal energy in the process.
