.A company wants to implement a simple and inexpensive robotic arm as shown in Figure below in one of their assembly lines. The material needed to make the arm has been defined, and we need to purchase the motion components. The arm is rotated around the base and has one pivot in the middle (total of two rotation points). Other information can be assumed. A motor will be placed at each pivot point. The end effecter will be made of magnetic material to pick up ferrous objects. Draw the signal flow diagram and table and make recommendations on the motors, magnet, and controller..
