Step 1: Step 1 : Basic Theory

In principle, forward kinematic uses the theory of trigonometry that is combined (joint). With the length (r) and angle (0) parameters, the End Effector position can be known, namely (x, y) for 2D space and (x, y, z) for 3D.

Step 2: Step 2: Model

The model is assumed with teta1 (0 degree), teta1 (0 degree), teta2 (0 degree), teta3 (0 degree), teta4 (0 degree). And length a1-a4 = 100mm (can be changed as desired). Angles and lengths can be simulated in Excel (download file).

Step 3: Step 3 : End Effector

From the matrix above the formula is simulated using Excel.

Step 4: Step 4 : Excel Simulation

In Excel1 is the basic theory of reference. For angles and lengths can be modified as needed. Which will later be known End Effector (xyz). For Excel is a system that I made.

Step 5: Step 5 : Arduino Diagram and Sistem

Supplies :

1. Arduino Uno 1 pcs

2. Potentiometer 100k Ohm 5 pcs

3. Cable (needed)

4. PC (Arduino IDE, Excel, Processing)

5. USB Cable

6. Cardbard (needed)

I put Arduino Uno in a used PLC box to avoid static electricity. For wiring diagrams see figure. For the Forward Arm Kinematic raft hardware system in accordance with the system that has been made.

Step 6: Step 6 : Arduino Program Upload

Arduino program files are in the download file.

Step 7: Step 7: Processing Simulasion

Program on File Downloaded.

Step 8: Step 8 : Final

I am from Indonesia. Greetings to all INSTRUCTABLE. I'm a new user here. I use Google Translate, so please forgive if there are inappropriate wording. The next colleague hopes to use the Dremel 3D printer. Thanks.
