Bionic Robots

Confusing Terms

Biomimetic

Biomimetic refers to human-made processes,

substances, devices, or systems that imitate

nature.

The art and science of designing and building

biomimetic apparatus is called biomimetic, and

is of special interest to researchers in

nanotechnology, robotics, artificial intelligence

(AI), the medical industry, and the military

Fully Replicating from nature

Biomimetic Robot

The biomimeticapproach mostcommonly strives toachieve this goal byreproducing someaspects of the biologicalsystem, for example,early plane designs thatinvolved flapping wingscan be considered asbiomimetics of birds.

Taking the Idea

Not Fully replicating it

Inspired from Nature

Bio-Inspired Robot

Bio-Inspired

This approach aims to

discover and capture an

essential idea that

underpins a biological

system, so that the same

idea can be implemented

technologically.

Bionic Robots

biology + electronics• Integrating Electro

Mechanical system to

living organisms

• Bionics usually means the

replacement or

enhancement of organs

or other body parts by

mechanical versions or

electrical add-ons

Which is Best?

• These approaches are not mutually exclusive, i.e., in

many cases a biomimetic solution can provide the best

technological implementation of a bio-inspired design,

but a biomimetic solution is not always optimal from an

engineering prospective.

• Fixed-wing aircraft turns out to be a more efficient

solution for carrying cargo than are designs that

replicate flapping wings of birds. Not too surprising,

perhaps, as typical birds did not evolve based on

capacity to carry heavy cargo across long distances.

• All these approach has its own Advantage and

Disadvantage

History

387 BC Archytas of Tarentum allegedly built a

kind of flying machine, a wooden pigeon

balanced by a weight suspended from a

pulley, and set in motion by compressed air

escaping from a valve (Biomimetic)

105 AD, Ts' ai Lun from China credited with

inventing paper, after watching a wasp create

its nest (Bio Inspiration)

When the real biomimetic Robot Came?

1970s,Robotic LOBSTER (designed by Joseph Ayers, a biology professor)

Robotic Lobster

The actions of real lobsters have beenreverse-engineered and programmed into alibrary of actions which give the roboticlobster a similar behavior as the real ones.

They not only resemble its physical shapeand movements but the way its artificialnervous system responds to variableconditions in its environment- such astemperature and heat.

Biomimetic Sensors

Vision Sensor - photosensitive devices to Binocular vision Cameras

Audition Sensor – Mic,Vibration Detection, echolocation behavior

etc (Crickets,Bats,Dolphins)

Touch Sensor – Pressure sensor,

Piezoelectric,capacitative,Electromagnetic

Smell Sensors – Electronic Noses

Taste Sensors -

Actuators

Pneumatic Muscles

Shape Memory alloys

Conducting Polymers

Hydraulic Actuators

Magnetic Actuator

Where it is going ?

From Nature

Combing these we are making biomimeticrobots….. Insects, Dragonfly's, Birds……..(Where)………………………….. Humanoid Robots…….which will perform as like Human

Structure

Bio-inspired ActuatorsBio-Inspired Sensors

Artificial Intelligence

Locomotion's in Robots

Crawling (To move slowly on the hands and knees

or by dragging the body along the ground )

Walking (2Leg,4Leg)

Climbing

Swimming

Jumping

Flying

Grasping

drilling

Control Architecture

Self Learning Robots

Evolving Robots

Collective Robots (Swarm)

Current Advancement

FESTO Albatross

PETMAN – Robotic Soldier (30 DOF)

Resistive & Capacitive Skin
