Hi! I am Keyur. I made a bumper car. At first I had a problem after it hit something it would not turn around. It kept on going on without stopping. After I fixed it, the car work fine until it hit something. When it hit something the programming would be lost. I fixed that by adding new batteries. After that I changed the wheels and put in new ones, but they kept on falling off. I fixed that by adding the old wheels. Now it works great!
Below is the picture and procedures.
to start
loop [if switch1 = 1 [ backward left forward ] if switch3 = 1 [ backward left forward ] ]
start
end
to forward
ac, thatway
on
end
to backward
ac, thisway
onfor 5
end
to left
a, thisway
c, thatway
ac, onfor 3
end
