Unless otherwise indicated, all the problems are from the course text, Craig, Introduction to Robotics. Unless otherwise indicated, each problem is worth 10 points.

  1. Write a Mathematica function that gives i-1iT as a function of the link parameters \alpha_{i-1}, a_{i-1}, \theta_i and d_i.

    You can find help on how to define a function in section 1.7.1 of the Mathematica book. The entire book is available on-line under the 'Help' menu in mathematica.

  2. 3.9
  3. For problem 3.17 (which you did last week) use your slick Mathematica function from problem 1 to compute the forward kinematics (0NT) in symbolic form. (3 points extra credit for using fancy Mathematica fonts to actually show Greek letters).
  4. 3.18 Also compute the forward kinematics.
  5. 3.19 Also compute the forward kinematics.
  6. 3.20 Also compute the forward kinematics.
Note: for problems where you have to compute the forward kinematics, you may have to assign your own notation for lengths of links, etc.
