The FIrst YeAr AT ItP

The Plant pet was a device and toy that helps people to control their emotion and stress by raising experience. Depending on care(touching a leaf), it can make a growth and dancing. It needs 9 times the number of touching for half inches growth.

<< Plant pet shapes>>

For the final work, I made different color structure. I didn’t like to choose green

color because of the reason it is a plant. However, because shape of the plant pet is now more like cute toys, so, I chose the green one rather than other color.

This is the final work with two motors for growth and dancing.

<<The final mechanism >>

By using the second motor for dancing, I had to install the second motor on the top of the lever. As Tom recommends the position, I would put the second motor the effort side rather than load side of the lever. And, for the balancing the lever and coming down the wire which regulate the height, I put the spring below the lever.

Now, depending on the touching time, the plant pet makes the growth and then if it’s grown up, it makes dancing by people’s touch.
