REVERSE ENGINEERING & THE EDUCATION SYSTEM: BIOMIMETIC ROBOTS Vivek Kumar Team Mentor

TEAM GENIUS

•  Founded in 2010 as a private robotics/science team

•  Global science competitions: •  FIRST Robotics •  IEEE robot design •  National eCybermission Competition •  Google Lunar X-Prize Moonbots •  Robocup Junior

KEY POINTS

•  Reverse engineering a biomimetic system can be used in the classroom to teach engineering and biological principles

•  The process of reverse engineering consists of two parts: operational and structural analysis

•  Reverse engineering can be used to gain a competitive advantage

BIOMIMETIC ROBOT SYSTEMS

•  Biomimetics, \ˌbī-ō-mə-ˈme-tik\, - the study of biological mechanisms and processes for the purpose of creating an artificial duplicate

•  Artificial Intelligence Research

•  Biological Studies/Labs- LEGS

•  Reverse Engineering Teaches two things: •  Biology e.g., anatomy •  Mechanical Engineering

REVERSE ENGINEERING PROCESS

Operational Analysis

Structural Analysis

According to ASME and PLTW Standards

Reverse Engineering: the process of taking something apart and analyzing it in detail

GLOBAL USE

•  Military

•  Software Engineers

•  Healthcare Professionals

•  Mechanical and Electrical Engineers

•  Tech companies

•  Designing/Manufacturing Companies

REVERSE ENGINEERING AND EDUCATION

Engineering, STEM,

Robotics

• Reverse Engineering Currently Existing Devices which display prominent engineering principles

• Provide insight into new and exciting technology • Facilitate design/engineering teaching • Help students gain leverage in the engineering design field

Non- STEM Related

Concepts

• Conceptually learn about another subject through reverse-engineering the device which uses that subject (In this case, biology)

• Example: Cosmetics through reverse-engineering the chemical composition of makeup
