Hi!
I am a new member of your community, and i would like to ask the following
question. Please excuse me if something similar has been already posted in
the past, but i performed a seach in the previous posts and i did not found
any answer to my problem.
What i would like to perform is the following task:
I have two LEGO Mindstorm robots. I would like the one of them to follow a
line in the floor (les call it "master") and another one ("slave") which
will follows in parallel according to the information’s that will receive
from the master. More specific, the master it will be equipped with a light
sensor in order to recognize the line in the floor. Furthermore, it will
continuously communicate through the infrared port with the slave, which
will not have any sensor at all, in order to guide him for performing
parallel movement. The line it will not necessary be a straight line. It
might have curves or even be designed a combination of curves and straight
lines. The two robots will be placed in parallel at the beginning of the
line. The aim is to cross the line by moving in parallel until the end of
the line. In the case that the line is straight, both robots should move by
the same speed. The tricky part of this task is when there exist curves. In
this case, the slave should increase or decrease the speed in order to
follow the master in parallel.
My main problems are two:
1) How can i transmit the exactly movement that the "master" robot perform
to the "slave" robot in order the slave one to follow it?
2) Does any one know if there exist any mathematical type that i can use in
order to calculate the increasing or decreasing speed of the "slave" robot?
How something like this could be developed in the NQC language? If this
could not be implemented in NQC, is it possible to be developed unter an
object-oriented language like JAVA based languages ?
Are there any similar examples where i can consult?
Thank you very much,
Vasilis Papaioannou
