- One of the simplest robots an engineer could make is a robot with only one "link," as shown in Figure 1a. The grasping end of this robot can only move in a circle of fixed length L. Using trigonometry, determine the x and y locations of the grasping end in terms of the fixed length L, and the variable angle 0 per Figure 1b. Create a MATLAB script that calculates this x, y position for any L and 0, and creates a plot of this configuration. (Recall: when we are plotting points, we use the plot ([x values], [y values]) command and put the x and y values of the points inside the square brackets [i.e. plot([0 x], [0 y]). Use this script to find and plot the configurations below: a a. L = 10,0 = 45° b. L= 10,0 = π/3 = c. L 5,0 205° d. L= 15,0 = -2/3 b Ꮎ ✗ yarrow_forwardCalculate the length x.

(10 points) Answer the questions as they relate to the graph shown. 2 From the ONE cycle shown, starting at the red star, does the graph look like a sine or cosine function? Is it reflected over the x-axis or not? What is the maximum value? What is the minimum value? What is the amplitude? What is the period? What is the phase shift? What is the vertical translation?
