In order to design and fabricate a novel artificial arm, several parameters are highly to be met. Specially designed mechanisms were adapted and modified for the previously designed Artificial Hand Gripper (AHG) [13]. The Figure 1 shows the design of the artificial arm from shoulder up to the end finger. It has four main axis:
1. Shoulder connected to the bicep 2. Bicep connected to the arm 3. Arm connected to the wrist 4. Wrist connected to the prosthetic hand
The artificial hand gripper design has 5 directions of motion (DOF) plus a grip movement. It is also similar to human arm from the number of joints point of view. These joints provide shoulder rotation, shoulder back and forth motion, elbow motion, wrist up and down motion, wrist rotation and gripper motion. A graphical view of all the joints are also shown in Figure 1.
