James Tacey, Aditi Shinde
Biomimetic Systems Neural Networks Biological Redundancy Self-Repair Artificial Intelligence
Neural Networks Groups of connected nodes or neurons Capable of finding non-linear patterns Highly adaptable to new inputs stimuli Excellent choice for control systems of
biomimetic locomotion
Biological Redundancy Many animals have redundant systems Systems allow continued functionality after a
limb or other system is damaged Redundancy prevents single point-of-failure in
the system Adaptation to a robotics allows for more
longer and more reliable functionality
Self-Repair Animals are capable of healing and repairing
damage done Repair algorithms and self-repairing materials Allows robot to become more durable and
capable of lasting in more harsh environments
Artificial Intelligence Still in early stages of research Robots can be ‘taught’ very simple tasks Would allow robots to adapt Wide variety of application in robotics, ability
to ‘learn’ variety of tasks
Artificial Muscles Shape Memory Effects Electroactive Polymers Chemical Muscles
Shape Memory Effects Use of materials that ‘remember’ shapes Material is ‘taught’ a shape Temperature controlled ‘muscle’ Slow but more durable ‘muscle’ for robotic
applications
Electroactive Polymers Polymers that change shape Electrically stimulated Highly pliable materials with a wide-variety of
applications
Chemical Muscles Similar to biological muscles Non-combustible chemical reaction drives
cylinder Higher energy density than electricity
Evolutionary Robotics Hardware and software co-evolution Use of genetic algorithms and neural networks Allows more adaptive design Requires less trial and error Effective for developing robotic gaits
