- 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.
