DOF - Design and Simulation of a 3-4 DOF Robotic Arm

I need a skilled professional to design, program and simulate a 3-4 Degree of Freedom (DOF) robotic arm using Simulink and Arduino. The primary application and specific tasks for the robotic arm have not been defined yet, and I am open to suggestions based on your expertise. This project will require you to demonstrate creativity and engineering skills in developing a versatile robotic arm.

Key Tasks:
- Design a 3-4 DOF robotic arm
- Program the arm using Arduino
- Simulate the arm using Simulink
- Suggest and implement potential applications and tasks for the arm
- Provide comprehensive documentation of the design and programming process

The ideal freelancer for this project should have:
- Extensive experience with Arduino and Simulink
- A strong background in robotics and mechanical engineering
- Excellent programming skills
- Creativity and problem-solving skills
- Ability to provide clear documentation

Please note that this project is open-ended and I am looking for a freelancer who can provide expert suggestions and deliver a robust, well-designed robotic arm.
