Synching the structural design, mechanical and the electrical power was the main challenge of this project.
Electrical Elements and Features are as followed: Power Supply 7.5 dc/ 1.5 A with power strip as switch, Arduino Uno Controller, ME Electronics Stepper Motor Driver, 200 steps per revolution (1.8 Degrees/Step) Stepper Motor.
Features of the selected origami are:
• Panels remain undeformed during the folding process
• Hinges are straight.
• The only deformation is the rotation of hinges
Reflections
The behavior of this origami with the Arduino system is similar to a spring, as when it moves inward, the pressure pushes is outward. So it needs a very strong power motor. While re-evaluating the project, I made the new origami structure with a lighter material, and I made a base for base the stepper motor and the whole structure. The base would embed the hardware of the project as well. I also embed the code. I noticed that we need to make a space between the arms and the upper surface to minimize friction.
