Biomimetic Design 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
