Hi! Our names are Jason and Bryan. Our third Lego project was a Wheel Chair. The Wheel Chair was a Lego made wheel chair with a joy stick that can actually move it! The wheel chair was hard to make but, a little easier to program. It was a two part bulding process. There first thing we built was the joy stick. It had an angle sensor which measuers the sticks angle and we used that to program it. The next thing we built was the actually wheel chair. It did involve a lot of work. The biggest mistake was that the whole bottom part didn't want to work. So we had to take it apart and see what was wrong. I think the problem was that It had extra bricks on it. That was pretty much the biggest mistakes we made. Next we programed it. We first made a procedure that would make it go forward, backward, left and right. Next we made a JOYSTICK procedure. This procedure measures the angle of the joy stick and moves the wheel based on the angles number. So it makes the wheel chair move. Next we made a start buttom which runs JOYSTICK forever. After that we had a race with our class mates own wheel chairs. We went second after Ernesto and Chris tired there wheel chair. We beat there time. Then we were the ones with the best time . However, they then tired again and beat us. So now we are trying to beat them and I hope we beat them.
Below is a picture of the Lego project and the procedures.
