One of our teammates previously volunteered as a friendly shopper at a senior home. She realized that there was a concern regarding the independent lives of the elderly. Many of them wish to perform tasks independently but due to their physical limitations, they are unable to do tasks such as carry groceries. With Tammio, they will be able to do such tasks without having to rely on someone else.

What it does

Tammio follows the user around and can carry items in its basket component.

How we built it

We used an arduino and ultrasonic sensors to detect how far the person is so it can follow them. We also used motor drivers and DC motors that allow it to move in a certain direction based on the distance readings from the sensors. Finally, we made a chassis to put it all together.

Challenges we ran into

We started as beginners so there were many challenges that we ran into. This includes figuring out the wiring, learning to code on the Arduino, and connecting the components together.

Accomplishments that we're proud of

We are proud of everything we accomplished. Prior to this makeathon, we all had little to no experience working with hardware so this whole makeathon was a big learning experience for us.

What we learned

We learned about circuits, how hardware works together, and how to code the arduino so that our components will do what we want it to do. (Big shoutout to Urmil who was a huge help throughout our learning experience at this makeathon -- we love you a lot ! <3)

What's next for Tammio - Your Personal Shopping Buddy

In the future, we hope that Tammio can be used for more than just a shopping function and can help the elderly, or physically challenged people with lifting items in the kitchen and perhaps even outside in their daily lives.
