Hi! Our names are Chris and Ernesto. On our first car we only had 2 wheel drive. Ernesto and I had the idea from another kid in the class to add two more motors, so our car would have 4 wheel drive. We ran into some trouble, because the car would go forward when it was turning left. This made it harder to make sharp turns. We never got that problem fixed. We also had to change some of our procedures, and that is where we finished using the legos.
Below is a picture of the Lego project and the procedures.
to forward
a, thisway
c, thisway
b, thatway
abc, onfor 5
end
to back
a, thatway
c, thatway
b, thisway
abc, onfor 5
end
to left
a, thatway
c, thisway
b,thatway
abc, onfor 5
end
to start
setpower 9
loop[
if switch1 = 1 [forward] if switch2 = 1 [back] if switch3 = 1 [left]]
end
