Underground Landmine Detecting UAV:

This aerial landmine detector is capable of providing virtual mapping of the traversed area and a concatenated map of the points of metal signatures, no matter whether it is a rough terrain or inclined surface. Since the aerial route is considered for surface exploration, the avoidance of assimilating the mine paths is reliably possible. The dynamism of path generation correlates to GPS coordinates of detected mines. A modified metal detection technique is developed based on electromagnetic radiation estimates, which can discriminate different metals, mines and bare explosives like RDX. The system has been tested under different consequences, such as different location of metals, variation of metals in size and type, varied experimental arena and the evaluated results affirm the reliability and cost-effectiveness of this system.This work has been accepted and presented  in Global Humanitarian Technology Conference , 2016 

Map Explorer : 

Map Explorer is an efficient design and implementation of a map integrated Surveillance-cum-rescue robotic system which can provide assistance during the accidental occurrences like earthquakes and structural collapses. When destructive events like quakes and mine collapses happen, often the victims do not get instant help to communicate with the outside world. An automated as well as manually operated robotic framework can be proven very useful in rescue operations and disaster management. The explicit design of the robot proposed here is meant to provide a definite map of the traversed area dynamically and it can also follow a specific map to reach a destination. Consequently, an HMI (Human Machine Interface)has been developed to control the substantial movement of the navigator from a moderate distance. The system has been tested in different set-ups under several challenging environments and the results obtained affirm its reliability.

This project won Gold Medal in International Robot PRIDE Competition 2015 organized by RAS- Malaysia Chapter and later accepted and presented in IEEE Region 10 Humanitarian Technology Conference , 2015 . 

Underground Landmine Detecting  UGV : 

In recent times, landmines have created unaccounted fatalities across the world. The detection of mines buried beneath the surface is paramount to avert inhuman risks associated with mine deployment and explosion. We started to work on this issue from 2015. We were the top four finalists in HRATC-16 which was held in Stockholm along with ICRA- 16 and became 2nd Runner Up . We got the chance to work with HUSKY robot developed by Clearpath robotics . This competition was conducted by RAS-SIGHT group and University of Coimbra, Portugal . 

Low Cost Braille Embosser :

Braille printers are the most convenient way to emboss the texts on a Braille paper and so provide written format of books for visually impaired (VI) students. But existing Braille embossers are more than 100 times expensive than that of normal printers which hinders its availability for individual utilization. We developed an innovative design with detail hardware implementation of a low cost Braille printer. Here the prime focus was to substantiate a design not dependent on sophisticated and expensive tools but in any way as productive as the complex and costly Braille printers. In the proposed six dot Braille system, major concentration was given to develop the linear actuators which emboss the impressions on the Braille paper to make dots to decode text language in Braille format. Unlike conventional mechanisms, gear DC motors were utilized to design efficient and inexpensive actuators. Apart from the actuators, the overall printing system involves cost efficiently designed inter-dependent components, such as self-contained printing software, wireless communication system, sensing mechanisms, and relevant light and compact mechanical setup.

Bengali Voice Controlled Robot :

The above picture was  a  prototype of Bengali voice controlled robotic motion based on an efficient and unique algorithm for accurately detecting Bengali voice commands. For the detection of Bengali voice commands to control the movement, our developed speech detection system incorporates Mel-Frequency Cepstrum Coefficients based speech feature extraction mechanism and a feature matching technique using Vector Quantization. This  Bengali voice controlled robotic motion could be very effective in rescue operation and disaster management system where a rescuer can dynamically give the rescue robot voiced instructions instead of being stagnant in a place for its controlling. Additional features including live video feedback and dynamic path generating algorithm for the traversed path, capability to accurately follow a specific map to reach a certain destination and dynamic obstacle avoidance as well as precise position and movement control system add to the flexibility and dimensionality of the robotic motion. Apart from its possible application in industrial automation, Bengali voice controlled robotic motion can also encourage the view of a robotic machine as a partner rather than a tool by providing a smooth, easy and flexible mean of self-reliant movement for the physically challenged people speaking Bengali language throughout the world.
