I am very new to Arduino stuff and I wanted to make something cool right when the package that I ordered came in the mail. I followed a few tutorials with LED's but that didn't satisfy my craving for something interesting. I came across some robot arm tutorials and instantly thought: yes. None of the tutorials worked and I was frustrated. I searched up how to control a servo with a potentiometer and later I evolved that into a very crappy robot arm that was probably one of the easiest things that you could make.

What I would do for building the robot arm is use popsicle sticks and elastic bands if you don't want to use elastic bands or anything permanent.

EXPANDED TECHNICAL DETAILS

Kinetic Geometry Basics

This entry-level robotics project demonstrates the fundamentals of 3-axis movement and servo coordination using a simplified mechanical structure.

• Angular Servo Control: Manages three standard SG90 micro servos (Base, Shoulder, Elbow). The Arduino maps 0-180 degree angles to physical positions, allowing for smooth, repeatable "Pick and Place" operations.
• Mapping Analog Input: (Advanced version) Utilizes three potentiometers to provide a "Manual Teach" mode; the Arduino reads the analog voltages and instantly mirrors the movement to the servos in real-time.

Construction

• Simplified Linkage Hub: Focuses on a lightweight 3D-printed or cardboard chassis that minimizes load on the servos, providing a responsive and high-speed robotic interaction for beginners.
