Evolvable Hardware and the
Evolution of Robot Bodies
Introduction
• Evolvable Hardware
–
–
–
Produced through the use of evolutionary
algorithms
Reconfigurable hardware, artificial intelligence,
fault tolerance & automated systems
Adapt dynamically and autonomously with
environment by changing behaviour and
architecture
• Evolution of Robot Bodies
– Robot bodies have changed an adapted to fit their
intended purpose
– From the original idea of humanoid robots in the
home
– More recently in medicine
– And military applications
Evolvable Hardware
• Conventional design methods sometimes
inadequate
• Hardware reconfigured due to unforeseen
faults
Evolutionary algorithms
• Biological mechanisms
• Generations of robots become increasingly
desireable
Examples of robot evolution
• University of Sussex
• Chalmers University of Technology, Sweden
Humanoid Robots
Homecare and Human Interaction
Different Design Influences
The Uncanny Valley
Uncanny Valley
Masahiro Mori
Correlation between
likeness and familiarity
More Human != More Empathy
Humanoid Robots
Many uses for this type of robot
Future development revolves around human
likeness
Finding ways to work with the uncanny valley.
Robots in Medicine
•
•
•
•
Improves precission
Decreases blood loss
Causes less pain (cost of painkillers)
Faster recovery after surgery (50% more
quickly)
• Allows remote surgery (over distance)
Evolution
• 85’ PUMA 560
– Precise
– Stable
– IK
• 88’ PROBOT
– Better design
– Better software
• 92’ ROBODOC
– Orthopedics
• daVinci Surgical System
– Miniaturized
– Multi-functional
Future
• Improved precision
• Improved sensitivity
• Nano robots
Military robots

Major Kenneth Rose :
“Machines don't get tired.
They don't close their eyes.
They don't hide under trees when it rains and
They don't talk to their buddies …
A human's attention to detail on guard duty drops
dramatically in the first 30 minutes …
Machines know no fear."
