Question 3 A four-link manipulator has been developed and designated as a spray-painting robotic manipulator. The manipulator is categorized as a PRRRR system, denoting its specific configuration. Detailed Denavit-Hartenberg (D-H) parameters of the complete manipulator is shown in Table 1. Table 1 i | $\alpha_{i-1}$ | $a_{i-1}$ | $\theta_i$ | $d_i$ --|---------------|-----------|-----------|----- 1 | $0^o$ | 0 | 0 | d 2 | $-90^o$ | 0 | $\theta_2$ | 1 3 | $+90^o$ | 0 | $\theta_3$ | 0.2 4 | $0^o$ | 0.5 | $\theta_4$ | 0 5 | $-90^o$ | 0 | $\theta_5$ | 0.5 (i). Explain the Denavit-Hartenberg (DH) parameters and their significance in robot kinematics. (ii). Develop the kinematic diagram of the complete robotic manipulator, assuming all revolute joints are in their neutral positions ($\theta_i=0^o$ and d=0). Clearly indicate frame orientations and offsets. (iii). Compute the homogeneous transformation matrix of the end-effector with respect to the base frame, $^5_0T$, for the joint configurations given in the Table 2. Table 2 Joint | value ------|------ d | 0.5m $\theta_2$ | $30^o$ $\theta_3$ | $60^o$ $\theta_4$ | $30^o$ $\theta_5$ | $90^o$

A student working an independent research project wants to investigate if there is an association between the amount of sleep someone gets and their body mass index (BMI) - an indicator of body fatness. For a sample of 45 students, she records their BMI and the average amount of sleep they get on weeknights over a two-week period. What would it mean for average amount of sleep and BMI to be positively correlated? It would mean that the more sleep individuals get, the higher their BMI tends to be. It would mean that individuals who get more sleep tend to have lower BMIs.
