DIY Acrylic 4-Dof Robot Servo Mechanical Arm.

1. Power it and test movements.Explain simply what a DIY acrylic 4-DOF servo robotic arm is and how it works (like a beginner guide),

   Or give you a full build guide with parts list, wiring, Arduino code, and step-by-step assembly?
   Here’s a quick breakdown so you can choose:

   
   What it is:
   "DIY" → You build it yourself.
   "Acrylic" → The body is made of acrylic sheets (transparent plastic).
   "4-DOF" → It has 4 Degrees of Freedom (like 4 joints that can move).
   "Servo" → It uses servo motors for precise movement.
   "Mechanical Arm" → Works like a mini robotic hand, can pick/place small objects.

   
   Main parts:
   Acrylic frame (laser-cut kit or hand-cut).
   4x Servo motors (usually SG90 or MG90 depending on size/strength).
   Servo brackets + screws + nuts.
   Arduino Uno or similar microcontroller.
   Wires + power supply.
   Joystick module or potentiometers (to control manually) OR pre-coded Arduino sketch.

   
   Basic steps:
   Assemble acrylic pieces into arm shape.
   Mount servo motors at each joint (base rotation, shoulder, elbow, gripper).
   Connect servo wires to Arduino pins.
   Upload code to control movements (can be joystick or programmed sequences).
