Find a picture of a robot not from Carnegie Mellon, on the web and display it. Comment on its application in terms of sense, plan, and act.
Deliverable: Create a webpage containing your text answers
(and any pictures) in HTML formal. Host it, and submit a link to it
in a plain-text file called p1.txt. The site must be
available for at least one week after the submission deadline to
receive credit.
Complete a C program to perform 3x1 vector and 3x3 matrix arithmetic. You are required to use this sample code.
The program should take from standard input one line at a time a sequence of expressions, described below:
A line with nothing on it should do nothing. The command END should terminate the program.
The following are the commands to be defined:
For vectors, a lower case letter followed by an = sign,
and then followed by three numbers sets the value for the vector.
For matrices, an upper case letter, followed by an =
sign, and then followed by nine numbers sets the value for a matrix.
To make things easier, assume there could only be 26 vectors and 26
matrices. Hint: there is a nice relationship between chars and ints
in C.
A vector or matrix on a line by itself followed by return should print the vector or matrix in their appropriate forms.
c = a + b ------ store the sum of a and b into c.
C = A + B ------ store the sum of A and B into C.
c = a . b ----- should compute the dot product of a and b and store in it in the first component of c. (Set the other components of c to zero)
c = a * b ----- store the cross product of a and b in c
C = A * B ----- perform matrix multiplication of A and B
v = M * x ----- perform the matrix-vector multiplication.
Take a look at some clarifications, sample input and a sample program here.
Tips for compiling in clusters.
Deliverable: Your commented source code named
p2.c. It must compile and run on the Andrew Unix
machines (we will use a build process very similar to the "Tips for
compiling in clusters.").
We'll introduce you to the basics of Matlab here. You may download it for free using your CMU License here. Using these files created by Sarah Tan, complete the following questions.
Load the robot warrior image you downloaded into Matlab and
save it in the variable ROB.
Save each RGB channel of the ROB image into
ROB_R, ROB_G, ROB_B.
Create a 10x10 matrix of ones and save it into ONE.
Change the values along the diagonal of ONE to 5 and save
that variable as FIVE.
Given TABLE1 and TABLE2, remap
TABLE1 and TABLE2, replacing the
last column with a column of the minimum element of the
matrix. For example, if TABLE1 is [1,5;
2,4; 3,2] the result should be [1, 1; 2, 1; 3,
1].

Collect ONLY your deliverables into a tar archive named
[AndrewID]_hw0.tar, where [AndrewID] is replaced by
your Andrew ID, minus the brackets. For example, user with AndrewID
odb would submit odb_hw0.tar. Submit the
archive via email to tdecker@andrew.cmu.edu. Failure
to follow instructions on this homework will result in an automatic
zero.
For information on creating a tar archive, please see
here.
For the most part, while working on Linux, all you'll
need to know is that you need to cd into the directory
containing your deliverables and then type
tar -cvf [AndrewID]_hw0.tar p1.txt p2.c p3.m.
It is expected that basic navigation abilities on the computing clusters is available. If you are having difficulty or are unable to do so, please notify a TA immediately.
