Research at Department of Mechanical Engineering, Amritapuri Campus
The Department of Mechanical Engineering at the Amritapuri campus was started in 2004. The Department offers a B. Tech. program in mechanical engineering. The competent and committed faculty members in the department have extensive academic, research and industrial experience. The department also has a team of dedicated and highly experienced supporting staff to help the students in the laboratories. Research areas include nano fabrication and nano precision optics. In addition, research is conducted in various fields of Mechatronics such as Robotics, Automation and Computer Integrated Manufacturing.

A Study of Robotic Gripper Driven by Flexible Micro-actuator based on an Innovative Technique
This project involves the development of an adoptable gripper with flexibility, dexterousness and load capacity analogous to the human hand for robotics and medical application. However the principle can be applied to various other applications such as micro robots, pipeline inspection robots, underwater robots and walking robots.
Experiments were conducted using various materials, rubber, plastic, neoprene, nitrile etc, The neoprene tubes (synthetic materials) were found to be more effective than natural rubber tubes during experiments. However, nitrile rubber is used for manufacturing the FMA for the robot gripper.
The humanoid multi-fingered gripper can be fitted to the amputated hand or those who have lost their hand in accident or in war. This artificial hand can also be fitted to the chair or cot using an arm and can be used to work like a servant to feed the patient.
Study of Tribiological Behavior of Aluminium Matrix Composites in Disc Brake Applications
This project involves the development of aluminium/SiC Discontinuously Reinforced Metal Matrix Composites (DRMMC) through liquid route and the study of their tribological properties.
The tribo pair selected for the system is commercially available brake pad. Experiments were planned based on Central Composite Design for Surface Response Method. The wear rate and coefficient of friction were analyzed using ANOVA techniques.
The objective of the project was to estimate the effects and interactions of the tribological parameters like Load, Temperature and Sliding Velocity. Different characterization studies like OM, SEM, EDX, etc. were used for characterizing the materials before and after the tests.
High Temperature Wear Studies on C/C Composites and Development of Coating Towards Better Wear Resistance
High temperature wear properties of C/C composites were studied through tests conducted on a High Temperature Wear Test Bed.
A composite of Fe-Cu was used as the friction material for the tests. A coating of SiC was developed on the surface of the C/C composite by using heat provided by SHS reaction between Ti and C. Characterization studies like OM, SEM, EDX, etc. were done before and after the wear tests.
