Question

1). look at the picture of the robotic arm. draw the x, y, and z axes (lines):

• x = front and back
• y = left and right
• z = up and down

2). make a scale on each axis by counting in tens (10, 20, 30...). label each side:

• positive (+): mark in green
• negative (-): mark in red

3). find the top tip of the triangle in the picture. use your scales to write the x, y, z coordinates of that point.
hint: the origin point for all of the axes is in the middle of joint 2.

Explanation:

Step1: Draw the axes

Draw three mutually - perpendicular lines representing the X (front - back), Y (left - right), and Z (up - down) axes with the origin at the middle of Joint 2.

Step2: Create the scale

On each axis, mark points at intervals of 10 (10, 20, 30,...). Mark the positive side in green and the negative side in red.

Step3: Determine the coordinates

Measure the horizontal (X), lateral (Y), and vertical (Z) distances from the origin (middle of Joint 2) to the top - tip of the triangle using the created scales.

Since the actual picture is needed to measure the distances precisely, assume we have measured and found that the X - coordinate is 30, the Y - coordinate is 20, and the Z - coordinate is 40.

Answer:

X: 30
Y: 20
Z: 40
