The science of control engineering involves modeling and ‘control’ of dynamical systems, or in simple words, understanding and manipulating systems that evolve with time. There is a wide gamut of areas that fall under this broad umbrella: economics, biology, environment and engineering to name a few. Our group studies the control of
mechanical systems (mobile robots), aerospace systems (spacecrafts), locomotion of microrobotic mechanisms, and the underlying mathematical framework to model, analyse and synthesise control laws for these systems, ie., differential geometry.

UAS are known under various different names and acronyms, such as ‘Unmanned Aerial Vehicle’ (UAV), ‘aerial robot’ or simply ‘drone’. An UAS typically comprises of an unmanned aircraft (UA), a ground control station (GCS) and a communications data link for the UA command and control from the GCS, host of sensors and a data acquisition device.

■ The robot, which is completely covered, can maneuver in any direction

■ Design is based on pendulum and yoke assembly

■ Entire electronics is within a spherical shell

■The gearless design supports jerky movements so that the application is not limited to a planar environment 

■ Each part inside the shell moves when the robot moves. Major challenges such as placement of electronic and mechanical components for weight balance and non winding of wire during the movement, were addressed

■ Two-pendulum design is developed to avoid gears in the assembly

IIT Bombay Racing is a Formula Student team, with 70 enthusiastic undergraduate members who aim to conceive, design and fabricate an electric race car through innovation to compete in international Formula Student events. The project challenges students to go the extra step in their education by incorporating into it intensive experience in building and manufacturing as well as considering the economic aspects of the automotive industry.We became the first ever Indian team to successfully build Aluminium Honeycomb Composite Chassis.

Textile dyeing in supercritical CO2 fluid offers multiple advantages as it provides an effective replacement of the traditional water based process which typically results in generation of large volumes of effluents and therefore an environmental stress. Additionally, SCFTD allows relatively lesser consumption of energy and solvents. Research carried out at IIT Bombay as well as by other groups internationally has shown that supercritical fluid (SCF) also provides an excellent medium for dye dissolution and fastening to fabrics.

A construction technique using lightweight geomaterials has many practical advantages because of their light self-weight, which makes it possible to reduce large deformations and differential settlement of soft ground or a foundation with poor bearing capacity. Nowadays expanded polystyrene (EPS) blocks are used with soil to make it lightweight material. Few applications like embankment construction, retaining walls and road construction can be mention. These blocks are manufactured by industry in regular shapes only.

A miniature CBR apparatus was fabricated which is very handy and portable, unlike to that of the standard CBR apparatus which is very heavy and consumes lot of time and effort for conducting the test. This apparatus is very useful in improving the soil properties especially with the new innovative nanotechnology based materials as the apparatus would require lesser quantity in mixing with respect to the lesser size of the mould.

The increase in population and the surge in urbanisation in both the developed and the emerging economies are resulting in a decrease of suitable land for development of infrastructure. Consequently, it can be expected that the need to quarry slag heaps and landfills containing such materials for use in construction, such as earthworks, pavements and buildings, will increase rapidly.

Consolidation of soil by surcharge loading with prefabricated vertical drains is an effective ground improvement technique in saturated cohesive soils such as marine clay. Four types of band-shaped drains made from singlelayer woven and non-woven jute geotextile filter fabric wrapped around a core of coir ropes or mats, designated as natural drains, were developed and fabricated. Laboratory marine clay confined discharge capacity and large-scale consolidation tests were conducted on the natural drains and commercially available polymer-based drains.

Contemporary research on gas turbine is focussed on achieving improved performance with lower emissions while avoiding combustion instabilities. Gas turbine industry is focussing mainly on simulations, for cutting down experimental iterations, cost and development time. In our laboratory, gas turbine combustion is simulated using a real life combustor with working variables of an actual gas turbine engine. An experimental facility is also created using one of the ‘can’ combustors of the gas turbine to imitate the actual scenario found in the engine.
