Figure 4: Inventor® simulation of the trajectory on the plane YZ
• Practice 4: Kinematic analysis: The last practice consists in the analysis of the
two types of simple movements: the simplest circular movement of an axle and the
more complex movement along a linear trajectory with a certain velocity. The first
one consists in moving a certain angle and measure the time with a chronometer
and to obtain the linear and angular velocity of the extreme element. These results
are compared with the one obtained from both Mathcad® and Inventor®
applications. The second one is to solve the inverse kinematic problem. So, firstly,
students must use the Mathcad® application to obtain the numerical solution and
then apply the values of the axle velocities to the simulation in Inventor®, and
finally apply it to the robot. This final practice must be carried out after the
theoretical analysis of the kinematic analysis of manipulators.
Evaluation and expected results
Activities evaluation to guarantee the skills acquisition established are planned from the
following statement: apply a system of continuous evaluation that enhance and incentive
the progressive study of the student during the subject development. They include nonpresential
ones, such as delivery of proposed works, and presential ones, such as seminars
where students solve more complex problems with the professor orientation and with the
help of computer applications or lab practices. Taking into account such statement, the
evaluation system is considered as follows: (i) Practices: To pass the subject is mandatory
to perform all the practices and deliver a report of them during the semester. The weight
in the final evaluation is 15%. (ii) Proposed homeworks: As in the case of the practice,
these activities are distributed along the academic year, trying to impulse that students
give a reasonable time for the study of the subject. They allow professor to know if the
learning process is effective or not. The weight is 15% of the final note. (iii) Seminars:
Only seminars where students solve problems individually are evaluated for knowing if
students acquire the required skills. In addition, the results validate the autonomous
learning of the students. According to the importance of this activity, its weight in the final
evaluation is 20%. (iv) Final evaluation: It is constituted by two options that student
could choose before the first third of the semester. First is a conventional writing exam
where student must demonstrate the skills acquisitions (solving new problems) trough
