Micro Servo Robot with Memory

Abstract

The Micro Servo Robot with Memory is a low-cost robotic arm that operates in two modes: Learning and Play. In Learning mode, an operator manually guides the arm through a sequence of positions using potentiometer controllers; each position is saved to memory at the press of a button. In Play mode, the arm autonomously replays the saved sequence, repeating the taught task without further human input. Built around an Arduino Micro, four servo motors, and four potentiometers, the system demonstrates how a simple microcontroller-based feedback loop can give a compact robotic arm a form of short-term “muscle memory,” making it a practical, affordable teaching tool for micro-assembly, pick-and-place, and small-scale automation tasks.
