IITs are on a quest to develop self-driving cars for India’s crazy roads

All the hardware and technology will need some serious adaptation for India’s extraordinary streets.

At the moment, SeDriCa isn’t much of a looker: it resembles a couple of stacked cardboard boxes precariously balanced atop three wheels. It’s not much of a mover either. Mounted with a beacon light, the vehicle ungracefully rambles along narrow, marked routes, usually on playgrounds, at a reluctant pace.

But Ankit Sharma and Rishabh Choudhary, final year students at the Indian Institute of Technology -Bombay, are convinced that the ungainly three-wheeler can provide the foundation for developing a driverless car for Indian streets. The duo leads the SeDriCa (short for self-driving car) project at the institute’s Unmesh Mashruwala Innovation Cell, where successive batches of students from multiple engineering streams have been working to develop an autonomous car since 2011.

They aren’t the only ones. For over a decade, IIT-Kharagpur, too, has been working to develop autonomous ground vehicles; similar research is underway in IIT-Kanpur. At India’s most elite engineering schools, the dream of driverless cars on Indian roads is turning into something of an obsession.

But for all their research into autonomous vehicles, all three IITs are working separately with scarcely any collaboration between the teams. With years of experience on the subject, it might make sense for these institutions to work together.

Nevertheless, it’s a useful fixation to have at a time when global carmakers and tech giants are throwing money and resources to develop self-driving cars. But all that hardware and technology will need some serious adaptation to be able to work on India’s extraordinary streets, where bovines, cars, pedestrians, and other assorted jalopies compete for space.

Made in India

In 2016, SeDriCa ranked fourth out of 36 teams from across the world at the Intelligent Ground Vehicle Competition, an annual student contest held at Oakland University. The competition involves avoiding obstacles, navigating a track while staying between the white lanes, and reaching specific global positioning system points.

Play

SeDriCa, which measures two feet by three feet, has an on-board GPS device, an inertial measurement unit that calculates motion and wheel encoders that track movement. A vision system on the vehicle is used to detect the lanes and LiDAR, a remote sensing technology that uses laser light, is employed to steer clear of static obstacles. All the data from these devices is collected and analysed by a set of algorithms to guide the vehicle along the required route.

The IIT-Bombay team is now working to adapt this technology for a small car for the Driverless Car Challenge of the Rise Prize, an innovation contest under the aegis of the Mahindra Group. Thirty one shortlisted teams must build a driverless car for Indian conditions, which will first be tested in a controlled environment, like a university campus, and then on city streets.

Sharma, Choudhary, and the rest of the team are still waiting to get their hands on the Mahindra E20, a four-door electric car that they’ll try and transform into a self-driving vehicle. After their experience with SeDriCa, they’re sure of pulling it off with around six months of testing.

Already, they are trying out some of the technology on the SeDriCa, which they’ll need to fine-tune on the E20. “The algorithms that we have implemented, they are working,” explained Choudhary, 21, a chemical engineering student who is the team lead on the Rise Prize. “For example, our positioning system is working on the roads. Even when the road is covered by trees, we have good positioning.”

“We are working on other sensors also,” he added. “We have completed pedestrian detection, so it can detect pedestrians and some types of vehicles.” Much more remains to be done, including developing and testing the vehicle’s ability to recognise and deal with traffic lights, road signs, and speed breakers.

From mine rescue to the road

The challenges aren’t much different for the Autonomous Ground Vehicle Research Group at IIT-Kharagpur, also competing for the Rise Prize. The Autonomous Ground Vehicle traces its roots to research that began at the institute around 2004. “There was a need for coming up with an autonomous rescue robot for mining applications,” recalled Debashish Chakravarty, an associate professor at the IIT’s mining engineering department, who heads the project.

By 2008, a group of PhD students from the computer science department got to work on building a driverless car, which then led to an IIT-Kharagpur team participating in the 2012 Intelligent Ground Vehicle Competition. “We actually have a test purpose robot, which was built from scratch and is used on a small portion of the campus road to run autonomously,” said Chakravarty. “And now, we are trying to fine-tune the technology for Indian roads.”

In 2013, a group of three students from IIT-Kharagpur spun off a company, Auro Robotics, to build autonomous shuttles for transportation within campuses, such as universities and corporate parks. Auro, backed by Y Combinator, a prominent Silicon Valley accelerator-turned-seed fund, is already testing driverless shuttles at California’s Santa Clara University. Last year, it raised $2 million to roll out autonomous shuttles across US universities.

Meanwhile, at IIT-Kanpur, Gaurav Pandey, an assistant professor in the electrical engineering department, is also on the bandwagon. A former research scientist at Ford’s automated driving group based in Dearborn, Michigan, Pandey is currently working on developing autonomous vehicle technology for a foreign carmaker. He declined to provide details of the project, which is backed by IIT-Kanpur, due to confidentiality considerations.

“I am mostly looking at the problem from the western perspective right now, so I haven’t really thought about how it will be translated to an Indian condition,” Pandey explained. “But we have started to look at it.”

“We have another project where we have outfitted a car with multiple sensors that are being used by these autonomous cars and we have started collecting data from outside the IIT-Kanpur campus, and within the campus also,” he added. Pandey and his team are collecting camera and LiDAR data from these trips to understand how traffic in Indian conditions differs from roads in the US and elsewhere.

After all, the driverless technology that works in California will scarcely suffice for Kanpur’s Chaman Ganj.

As India turns 70, London School of Economics asks some provocative questions

Is India ready to become a global superpower?

Meaningful changes have always been driven by the right, but inconvenient questions. As India completes 70 years of its sovereign journey, we could do two things – celebrate, pay our token tributes and move on, or take the time to reflect and assess if our course needs correction. The ‘India @ 70: LSE India Summit’, the annual flagship summit of the LSE (London School of Economics) South Asia Centre, is posing some fundamental but complex questions that define our future direction as a nation. Through an honest debate – built on new research, applied knowledge and ground realities – with an eclectic mix of thought leaders and industry stalwarts, this summit hopes to create a thought-provoking discourse.

From how relevant (or irrelevant) is our constitutional framework, to how we can beat the global one-upmanship games, from how sincere are business houses in their social responsibility endeavours to why water is so crucial to our very existence as a strong nation, these are some crucial questions that the event will throw up and face head-on, even as it commemorates the 70th anniversary of India’s independence.

Is it time to re-look at constitution and citizenship in India?

The Constitution of India is fundamental to the country’s identity as a democratic power. But notwithstanding its historical authority, is it perhaps time to examine its relevance? The Constitution was drafted at a time when independent India was still a young entity. So granting overwhelming powers to the government may have helped during the early years. But in the current times, they may prove to be more discriminatory than egalitarian. Our constitution borrowed laws from other countries and continues to retain them, while the origin countries have updated them since then. So, do we need a complete overhaul of the constitution? An expert panel led by Dr Mukulika Banerjee of LSE, including political and economic commentator S Gurumurthy, Madhav Khosla of Columbia University, Niraja Gopal Jayal of JNU, Chintan Chandrachud the author of the book Balanced Constitutionalism and sociologist, legal researcher and Director of Council for Social Development Kalpana Kannabiran will seek answers to this.

Is CSR simply forced philanthropy?

While India pioneered the mandatory minimum CSR spend, has it succeeded in driving impact? Corporate social responsibility has many dynamics at play. Are CSR initiatives mere tokenism for compliance? Despite government guidelines and directives, are CSR activities well-thought out initiatives, which are monitored and measured for impact? The CSR stipulations have also spawned the proliferation of ambiguous NGOs. The session, ‘Does forced philanthropy work – CSR in India?” will raise these questions of intent, ethics and integrity. It will be moderated by Professor Harry Barkema and have industry veterans such as Mukund Rajan (Chairman, Tata Council for Community Initiatives), Onkar S Kanwar (Chairman and CEO, Apollo Tyres), Anu Aga (former Chairman, Thermax) and Rahul Bajaj (Chairman, Bajaj Group) on the panel.

Can India punch above its weight to be considered on par with other super-powers?

At 70, can India mobilize its strengths and galvanize into the role of a serious power player on the global stage? The question is related to the whole new perception of India as a dominant power in South Asia rather than as a Third World country, enabled by our foreign policies, defense strategies and a buoyant economy. The country’s status abroad is key in its emergence as a heavyweight but the foreign service officers’ cadre no longer draws top talent. Is India equipped right for its aspirations? The ‘India Abroad: From Third World to Regional Power’ panel will explore India’s foreign policy with Ashley Tellis, Meera Shankar (Former Foreign Secretary), Kanwal Sibal (Former Foreign Secretary), Jayant Prasad and Rakesh Sood.

Are we under-estimating how critical water is in India’s race ahead?

At no other time has water as a natural resource assumed such a big significance. Studies estimate that by 2025 the country will become ‘water–stressed’. While water has been the bone of contention between states and controlling access to water, a source for political power, has water security received the due attention in economic policies and development plans? Relevant to the central issue of water security is also the issue of ‘virtual water’. Virtual water corresponds to the water content (used) in goods and services, bulk of which is in food grains. Through food grain exports, India is a large virtual net exporter of water. In 2014-15, just through export of rice, India exported 10 trillion litres of virtual water. With India’s water security looking grim, are we making the right economic choices? Acclaimed author and academic from the Institute of Economic Growth, Delhi, Amita Bavisar will moderate the session ‘Does India need virtual water?’
