Be sure to write CLEARLY! 1, (5 points) Write the Matlab commands to generate a time vector t that starts with 10, ends with 20, and has a sample period of 0.5. >> if: [\G :. 0% 3/201.) 2. (6 points) For the time vector t deﬁned above, what are: a) t(3), b) 13(8) and c) the length of the vector? a) {K b) [’65 c) M a—-—.. l 3. (3 points) Evaluate each of your team members performance by ﬁlling out the following table Use the following ranking: lmexcellent, 2=very good, 3zgood, 4=less than satisfactory, 5=totally lame Team Member Name | Ranking Team Name: 4. (5 points) Write down the dynamic model for a robot’s translational position x and rotational position 6. Included in the model are the constant sample period A, trans— lational speed uk and rotational speed '03:. \$k+1= XlQJV— AULJQCUCED(®LAB (1) E 19+]- (":5 I I 1 r i R r b EV} . ‘7‘». 5. (5 points) The wall—following control is given by 33k — RSk—i T= ' <2) Where kp, id, dsep and umm are positive constants. Substitution of (2) into (1) gives .the closed—loop dynamic model of the robot. ”k = ”110111: vi: = l(31::(33ls: _ deep) "l" kd Write down the closed—loop dynamic model of the robot. ARM: Kiel?
