Projects for BEng
Biomimetic robot I: Mechanics of walking and design of walking robot
The goal of this project is to explore the control of locomotion in two-legged robots. We
begin with a quick look at animals that stand and/or walk on two legs. We then turn to
human locomotion, since humans are the model of excellence for biped locomotion.
First part of this project will study the mechanics of locomotion in two-legged creatures
and the second part of the project will engage in design and development of such
creatures.

Biomimetic robot II: Hydrodynamics and mechanics of swimming and design of
swimming robot
The goal of this project is to study the locomotion of aquatic animals in water. We begin
with a quick look at aquatic animals that swim in water using fins. These aquatic animals
use a variety of mechanisms to propel themselves in water. We then turn to simple
mechanism of swimming which propels and manoeuvres like a tuna. Across the broad
spectrum of fish form and movement, tunas are most desirable as a vehicles platform.
They are very streamlined, relatively rigid in the fore body and propel with low amplitude
movements in conjunction with a high-performance hydrofoil.
First part of this project will investigate hydrodynamics and mechanics of swimming of
aquatic creatures and the second part of the project will engage in design and
development of such creatures.
Biomimetic robot III: Aerodynamics and mechanics of flying and design of flying
robot (Ornithopters)
Flying vehicles with flapping wings are known as ornithopters. In recent years there has
been growing interest in ornithopters, particularly in small sizes in which the ratio of
wing area to body mass can be sufficiently large to make flight of this kind possible. This
project considers the kinematics and power requirements for a flying device using beating
wings. The goal of this project is to study the aerodynamic locomotion of flying
animals/birds/insects. We then turn to simple mechanism of flying which propels and
manoeuvres like a blowfly, which has mass of 100gm, a wing length of 11mm, and a
wing beat frequency of 150 Hz. It will require an actuator power of about 8nW.
First part of this project will investigate aerodynamics and mechanics of flying creatures
and the second part of the project will engage in design and development of such
creatures.
