Week 2 Updates

Before class, we met to discuss everyone's role in the project and go over our design idea again. Attached below is a description of how the work will be divided among the group.

In class, Dr. Terranova explained that our initial design would be difficult to make move quickly in order to produce a sufficient scare, so we have reworked our design idea. Instead of a track-like design that the bear would roll forward on, we have decided to imitate a Jack-in-the-Box. The bear will instead be hidden from view (laying down) and then when the motion sensor is activated, it will pop up and hopefully frighten the guests.
Additionally, we ironed out some dimensions and a materials list in terms of what we need to buy and what we have in the Innovation Studio. Arduino seems to be our best bet as of now, so some of the team researched tutorials and other information about coding and what kind of motors and electrical equipment we will need.

Today, we decided on the specifics of our design. The main bear will be loaded on a spring that will be released when a motor rotates and allows the loading arm to spring forward. There will be two smaller bears in the back that will be in continuous motion while the main scare-bear springs. The audio will come in first after a first motion sensor is activated, then a second motion sensor will activate some lights to illuminate the "painting," and then a third and final motion sensor will activate the motor that will release the bear.
A rotational servo motor will most likely be used for the release of the spring bear. DC motors can be used for the rest of the motion in the painting. Strobe lights will be used in the code to turn them on and off when the bear is released.
Our materials list as of now is as follows:

Our materials list as of now is as follows:
- lights (LEDs for bikes on Amazon)
- speaker
- battery
- bears.
