Professor Builds A Car That Can Avoid Accidents

A team at MIT led by Prof. Dina Katabi and Swaroon Kumar have come up with a car that can avoid the inevitable if need be, literally! Named ‘CarSpeak,’ it enables efficient wireless communication with sensors that can view pedestrian, thereby allowing the car to stop safely in advance.

How does the car work?
Autonomous cars are designed to automatically navigate towards their destination without human intervention. In general, autonomous cars have two components: First, they use sensors to gather information describing their surroundings; Second, they use this information to plan a safe and efficient path towards their destination.  ‘CarSpeak’ provides autonomous cars a wider field of view by gathering sensor information from other cars and static road-side infrastructure.

The approximate cost?
Our system is restricted to the communication system for the car.  The WiFi cards used in the car cost $20-$50 in the market. Currently, autonomous cars’ cost varies from $40,000-$500,000. Of course, the cost is expected to reduce once they are mass produced.

Will it take to the roads?
Our car has been test driven several times on the roads of our campus. We hope to test it on public roads once the licensing procedures are complete.

How did you come up with the idea?
While researching, we realised that autonomous cars lack this aspect of giving warning to the pedestrians before hand. So, we thought of developing some projects that can handle this aspect and thus the idea cropped up in our mind. ‘CarSpeak’ is a communication system that is tightly integrated with autonomous driving.

Can it be driven on chaotic Indian and asian roads?
‘CarSpeak’ is designed precisely to tackle hidden objects beyond an autonomous car’s sensor range. The sensors become all the more active in over crowded roads. So, we expect addressing this challenge to be very important for autonomous driving to be successful in crowded or busy roads, in countries like India.

What is your future project?
I worked on MegaMIMO designed to make wireless networks, support a large number of devices in a small space. 

BASIC FEATURES

  • Autonomous cars get about with the help of sensors, continuously scanning the road ahead for dangers. But blind corners provide a huge challenge for the vehicles as these sensors, like human eyes, can’t see as far ahead as the human eye or look around bends. Car Speak could eliminate this issue in one go, though only if the technology is fitted to most vehicles on the road. 
  • Car Speak raises the possibility of autonomous cars driving at higher speeds on motorways.
  • CarSpeak provides a wireless communication system that augments a vehicle’s field of view with information from other cars and infrastructure in their vicinity.
  • Car Speak has the potential to make the footprint significantly larger.
  • CarSpeak enables autonomous cars to be even safer than humans by detecting hidden objects.
  • CarSpeak can also benefit human driven cars by providing them advance warnings about objects that they couldn’t see before.

  • About Us

Times Newspaper in Education (Times NIE) is a novel program that helps students ‘Stay Ahead’ and aims at making ‘Learning Fun’. It introduces concepts that help individual growth and development beyond school curriculum.

A brainchild of The Times of India, the world’s leading English newspapers, Times NIE nurtures progress and innovation. Adapted from the international concept, Times Newspaper in Education program (Times NIE) was initiated in India in 1985.

Today we have over 3000 schools and over 9 lac students subscribing to the programme, spanning 16 cities viz. Delhi, Mumbai, Pune, Bangalore, Kolkata, Chennai, Hyderabad, Ahmedabad, Kochi, Lucknow, Coimbatore, Chandigarh, Dehradun, Vijayawada, Visakhapatnam, and Jaipur.

The Times of India Student edition, a customized student newspaper exclusively for the students, packs a powerful punch in terms of content that leads to a smarter and superior learning experience. The information is crafted such that it finds use in classroom discussions, thus making it relevant and current. It truly gives education a new dimension by fostering the simple habit of reading which in turn paves the way for a confident, informed and aware individual. A newspaper that inspires young minds and equips them to face challenges of today’s world, making way for global citizens.

Empowering students with new cutting-edge knowledge through various educative and informative activities is a commitment and tradition of Times NIE. The programme serves as a catalyst of education and interaction, as well as a window into the minds of the quintessential Indian youth. On a significant scale Times NIE comprises diverse interesting activities and events that boost the child’s passion for learning, while revealing hidden talent.

While you are aware that The Times of India is among the leading English Newspapers across the world, it has consummated its position as an everlasting winner. With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN). In 2008 we were honoured by the International Newspaper Marketing Association (INMA), yet another international recognition for ‘Youth Audience Development’. In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
