This truly shows how FIRST can affect us and help each other out. I just wish more of the world knew.

We used the IR sensors at the front (3) that were mounted in a way that they look for walls and stairs. They simply measure the distance between the walker and the ground, 60 times in one sec, and if that distance increases or decreases, they turn of the movement and using the logic try to correct or protect the walker.
This project not only changes the whole aspect of the Baby's life, but it also impacted the students on a greater scale. It gave them an insight of how they can use this knowledge and make this world a better place to live for everyone.
