Final answer:
The student is asking about finding the upper and lower bounds of the inertia matrix M for a 3-link RPR robot arm using norm 1 criterion, within given ranges of motion for the joint angles and the prismatic joint variable.
Step-by-step explanation:
The question pertains to the dynamic equations of a 3-link RPR (Revolute-Prismatic-Revolute) robot and involves determining the bounds for the inertia matrix M using the norm 1 criterion. This problem falls under the field of robotics, a topic within mechanical engineering, and more specifically, it involves robotics kinetics and dynamics. The range of motion for the joint angles is given as [-90°, 90°] and for the prismatic joint variable d2 as [0, 1.5]m. The norm 1 of a matrix is the maximum absolute column sum of the matrix. In this problem, one would need to consider the possible configurations of the robot within the given ranges to determine the bounds of the inertia matrix. One would also need to calculate the inertia for different configurations and use these calculations to assess the maximum and minimum values that the elements of the matrix M can take, considering the limited range of motion specified.
