6-DOF Robotic Arm Kit (MG996R Servos, Acrylic)

About this product

Six axes, a working gripper and enough reach to move objects across a desk. The arm is cut from 3 mm acrylic and driven by five MG996R metal-gear servos plus an MG90S in the gripper, so it behaves like a scaled-down industrial manipulator rather than a toy. A PCA9685 16-channel PWM driver keeps servo timing steady and takes the load off the Arduino.

There are two ways to control it. The potentiometer panel lets beginners move each joint by hand and record a sequence, then replay it on a loop, perfect for a demonstration table. Older students can drop the potentiometers and drive the arm from code, from a phone over Bluetooth, or from a Python script over serial, which opens the door to inverse kinematics and pick-and-place assignments.

Assembly takes two to three hours and needs patience with servo horn alignment; the illustrated manual covers the correct centring procedure step by step. A 6 V 5 A adapter is included because USB power alone cannot run six servos.
