Introduction

Introduction

  • Motivation – Provide more efficient and accurate method for recording sound at Pogo Studios


Objective

Objective

  • Create a wirelessly controlled robotic device capable of 10 movements

  • Program device to recall stored locations


Design

Design


Power supply

Power Supply

  • 11.1V 5Ah LiPo Battery

    • Wired into 5 motor drives (4 XY, 1 Z)

    • Delivers 3.2A when 4 motors running
