The Future of Mobility in India
Industry 4.0—enabling innovative processes, digital manufacturing and automation—has the potential to disrupt the industrial value chain and push automotive sector to rethink the way they do business. Moreover, stringent regulations are evolving so rapidly that the automotive sector might need to rethink about their operational aspects to comply with regulatory and other guidelines

Simple Obstacle-Avoiding Robot
Presented here is an obstacle-avoidance robot without microcontroller (MCU). The obstacle-avoidance feature is commonly found in autonomous cars and robots. Most obstacle-avoidance robots are costly and difficult to build because of MCUs. This project is simple and does not use any complex circuitry except a relay driver

AUGMENTED REALITY: Modern Businesses Require Modern Solutions
Although upfront investment is high for AR technology, the ROI comes quick through such benefits as higher customer engagement, lower operational errors, higher efficiency and higher productivity. AR also reduces financial expenses while cutting down on training investments, reducing rates of returned orders, reducing risk of product damage during demonstrations and so on

An IoT Solution to Keep Tyre Failure at Bay
Investments in transportation are often a necessity for large businesses, educational institutions and organisations. A major concern during travel is the wearing out of tyres in the middle of the road, which can cause unprecedented delays, unwanted hassles and some heavy expenses. Tyre changes for a single commercial vehicle can add up to Rs 200,000 per year. On top of that, changing tyres on the road can be strenuous. While there are many smart solutions available for businesses to keep a tab on their vehicles’ engine health and fuel system, businesses require platforms to stay aware about tyre healths, too. Maharashtra-based startup Tyre Express has taken up this challenge to turn the tables

GREEN TECH: Rohit Bansal, founder, Purelogic Labs India: “People in the country do not have in-depth knowledge about the various types of air pollutants”
Air quality has become a matter of concern in urban Indian cities, like Kolkata and New Delhi, that suffer from hazardously high air quality index (AQI) consistently. To address this problem, administrations and consumers alike need to stay updated about the air conditions in real time. Rohit Bansal, founder, Purelogic Labs India, talks to Paromik Chakraborty of Electronics For You about how national air quality monitors, like their AQI India platform, can help us take the first step towards better health

In-Car Sensor to Prevent Drunken Driving
Driving under the influence of alcohol is dangerous. This risky yet common habit needs to be avoided completely. It can be life-threatening, not only for the driver but also for the co-passengers and bystanders on the road. On-duty police officers keep a vigilant eye to detect intoxicated drivers. However, it is not possible for them to be present everywhere. It is the primary responsibility of car-owners to ensure they are in a condition to drive when taking the wheels. To help them take this responsibility and be sure first-hand, Canada-based Sensor Diagnostics has come up with a solution called Sober Steering

A Smart Water Purifier at Zero Purchase Cost
Quality of drinking water is one of those things that we simply cannot afford to compromise—not one bit. Water-borne diseases like diarrhoea, hepatitis, typhoid and cholera, or illnesses due to contaminants like arsenic or lead, can cause large-scale health hazards. Reports suggest that, in India, more than 10,000 lives fell victim to such diseases from 2013 to 2017. To monitor water quality and reduce contamination, smart sensor-based technologies and filters are being used, which often lead to high capital costs for consumers
STARTUP ZONE
Digital Dairy Farming, an Unexplored Land of Infinite Possibilities
The dairy industry contributes around four per cent to India’s GDP, enjoying equal output value with rice and wheat. Still, government involvement is lacking to modernise and stabilise this sector. Farmers are losing money due to non-efficient dairy farming, comparatively weak genetics of Indian cattle, high input cost and non-data-oriented farming. These bottlenecks are preventing Indian farmers to derive maximum value from their farms and dairy businesses

A Personal Translator On-The-Go
We are often unable to communicate well with local people while visiting foreign countries, or even some Indian states, mainly because of not knowing their language. A substantial population in the world, and even India, does not speak English. Sure, we have Google Translate, but it is not the optimal solution for fluent verbal communication. Travis, a Dutch-based startup, has come up with an intelligent wireless translator to close this language barrier

SPORTS: Technologies That Have Transformed the Sports Experience
You do not need to watch too many games to know that referees have limited visibility and they too can make mistakes. Technology can change this by helping them make better and more accurate decisions. There are many technologies that can assist a referee on the ground (central referee) or through the third empire who is looking at the game from outside the ground (video-assisted). If you do not think these technologies are necessary, just imagine for a while how hard it is to keep an eye on all players on the ground at one time while closely keeping watch on the ball
