Inspiration

Our workspace was so cluttered with wires and small hardware. We wished there was some place to put all of our things. Thus, noom noom was born.

What it does

noom noom eats anything you hand it and stores it inside its body. Feed noom noom and it'll do a little dance!

How we built it

The eating mechanism and body design was sourced from EunChan Park on Youtube. We started with a paper model then switched to a 3D printed version. It is operated using an Arduino Uno that moves a micro servo motor to open and close the lid when a movement, such as placing an object into noom noom's bin, is sensed by the IR proximity sensor. The chassis was made from two DC motors which are the wheels controlled by a DC motor driver and a 6V battery source. The movement pattern for noom noom's dance is coded into the Arduino Uno.

Challenges we ran into

Some of our hardware was broken and we had difficulty acquiring replacements due to inventory. The dimensions of the paper model were not exact and so our first prototype had some mobility issues. We also had to change our original chassis design due to complexity, inventory and time constraints.

Accomplishments that we're proud of

Despite the measurement issue, we were proud of our working paper model of the eating mechanism. We were also pleased that our Arduino components all functioned as expected.

What we learned

Order parts ahead of time and test hardware once you acquire it. Plan the design ahead of time and do not overestimate your time, resources and ability.

What's next for noom noom

Adding a HC SR04 sensor to the chassis for object avoidance and remodeling the hand to allow noom noom to roam around and pick up objects by itself. Also, adding a speaker to play sounds as noom noom dances and eats.
