This is a web page about a project I made in computer class. I made a Lego bumper car. I had to figure out how to program it with new software and a new Lego kit which uses the RCX brick. I took a long time to figure out the different commands because we never used it before. I had to figure out how to make the motors turn on at the same time for a specific time because the software wouldn't let us talk to both motors at the same time. After days of trying different commands to see if they worked, I finally found out what to do. I had to use the WAIT command instead of the ONFOR command. When I finally figured that out I had to make it turn when it bumps into something. Below is a picture and the programming that I wrote:
to start
athisway
cthatway
asetpower 4
csetpower 4
loop [drive]
end
to drive
ifelse switch1 [ aoff coff ard crd right aon con] [aon con]
ifelse switch3 [aoff coff ard crd left aon con] [aon con]
end
to forward
athisway
cthatway
aon con wait 20 aoff coff
end
to right
asetpower 4
aon wait 4 aoff
end
to left
csetpower 4
con wait 3.5 coff
end
