EX Robotics Question

["Bruce Cattanach" <bruce.cattanach@xxxxxxxxx>]

My colleague, working with our 5th grade has this question
dealing with MW ExRobtics...  Thanks

I need a program that will start a robot with a touch
sensor, follow a line and stop the robot with another
touch sensor. So far it can start with a touch sensor and
follow the line. I cannot get another touch sensor to work.

This robot has a touch sensor in the back and front and is triggered from
another robot coming from the back.  After it starts, and follows a line, it
contacts
a third robot which starts following a line,  the front sensor will trigger
the robot to stop.
A relay event, with three robots.  All following lines and triggering
others.

I know,  we aren't supposed to be doing this with Fifth graders,
but we just can't help ourselves.  LOL

The program so far is --

to relay
waituntil [switch1]
aon con
asetpower 2
csetpower 2
loop[
left
waituntil [onblack]
waituntil [not onblack]
right
waituntil [onblack]
waituntil [not onblack]
]
end

to left
aon bon coff
end

to right
con bon aoff
end

to onblack
output reflect2
end

any help will be greatly appreciated.
