This year, right after the Championship, our team worked on helping a disable kid with his mobility. It was really challengin as the kid was only 10 months old, and has limited legs and arm. We used ultarasonic sensors ( which was really hard to program) and infrared sensors to make it more safe. Other than that, the user interface was another BIG porblem.
Our hardwork got paid, and our county approved it with $ star safety rating.

Thisproject was not only appreciated by the community , but also by the well known doctors at INOVA Fairfax Hospital. I guess, this year we are goin to use this technological success as the basis of our Charimans award entry; not mentioning the community service and FIRST_OUT_Word boths we had done so far.
