HUBOT- Bridging the gap between Human and Robot Interaction

A variety of robots are available today and each having their own, unique applications. However achieving an efficient means of communication with these robots is still problematic. It is difficult for a robot to accurately analyse and follow voice commands given by its master. During human-human interactions, multiple sounds are simultaneously processed by our brain and we still segregate the sound containing the information we want. This is not the case with robots; they are unable to differentiate various sounds in its environment. This is a major roadblock in human-robot interactions.

Scientists Design Highly Sensitive Force Sensor

Scientists at the Indian Institute of Science, Bangalore have proposed a new force sensor that can detect changes in forces as small as ten nano-Newtons. That’s one hundred millionth of a Newton, the unit of force! The proposed sensor uses a special crystal with specific resonation characteristics that can sense these tiny forces. Sensors that detect small forces are used in the fields of chemical sensing, bio sensing, temperature sensing, humidity sensing, pressure sensing, and stress sensing. An eight-member team from the Department of Electrical Communication Engineering and the Center for Nano Science and Engineering headed by Prof. T. Srinivas, is behind this innovation.

Novel methods for better flood prediction

Prediction of rainfall and flood is very important for densely populated country like India. Scientists at the Indian Institute of Science (IISc), Bangalore have proposed a new method for predicting flood magnitude, which is more effective than conventional methods. The team consisted of Prof. V.V. Srinivas and Dr. Bidroha Basu of Department of Civil Engineering.

Developing algorithms for better water resource management

Scientists at IISc may have the solution to one of the major problems faced in our country – water resource management. By applying a technique called the 'Multi-criteria Decision Making' they are trying to address various water management and irrigation challenges.

Improved solar trackers for better solar energy harvesting

Researchers from the Indian Institute of Science have developed an improved version of a device that can track and orient mirrors, also called heliostats, towards the Sun. These tracking devices are important components of large scale solar thermal power plants, and are not new. But, the new version, developed at the Indian Institute of Science, is lighter, cheaper, remains stable even in strong winds, and of course, is better at tracking the sun.

New tool to detect whispers may help cancer patients

A two member research team from the Indian Institute of Science has developed a method to detect whispered speech even in a noisy recording. With further research, this can be incorporated into a tool to reconstruct normal speech, which can be useful for people with laryngeal (voice box) cancer.

An Internet-of-Things network for IISc campus

Over the past few decades, scientists have sought to develop a system where machines can talk to other machines without any human interaction. In 1999, they finally conceptualized a system called the Internet-of-Things (IoT) – a network wherein objects are given unique identifiers (IP addresses) and are provided with a platform for the transfer of information. Researchers from the Indian Institute of Science (IISc) seek to capitalize on this concept and have identified appropriate technologies for the employment of an IoT network in the campus.
