Chennai :

This team of four engineers are going great guns since the launch of their start-up AI Aeronautics six months back. It has been incubated at Maker Village, and is making waves even in international market due to their penchant for customisation.

“The idea emerged while I was pursuing my PhD in Aerial Robotics and Artificial Intelligence. But, the idea to launch a start-up is a recent one,” said Vishnu V Nath, founder and VP, engineering. It was set up with a seed investment of Rs 15 lakh. “The money was pooled in by us. Later, we got Rs 10 lakh from the government as a part of Niti Prayas,” he said.

The aim was to develop a viable product that matches the requirement of the customer at a minimal cost. “We build a customised flying platform that can be used in reconnaissance, aerial 3D mapping for survey, smart agriculture and disaster management,” he said. The efficiency of the product was proved during a demonstration that was held for the State Disaster Management Authority.

“Our drone carried out an aerial 3D mapping of the flood-affected areas. It helped predict the level to which water will rise if the dams are opened again. This will help in disaster management,” he said.

The police and forest departments have also approached him. “We gave a demo to Kerala police. They want to use the product for surveillance, crowd monitoring and VIP security. Features like the ability to downlink high-resolution real-time videos, an artificial intelligence-based algorithm to detect and track the number plates of suspect vehicles and also identify persons of interest through facial recognition make our product attractive to them,” said Vishnu.

The hybrid UAV that AI Aeronautics has developed can fly up to two hours within a 40 km radius. “We worked with the Archaeology Department for a pilot project in which the UAVs were used for aerial mapping and disaster estimation by creating a map of the Aranmula Parthasarathy Temple,” he said.

At present, the start-up is doing a research project with IIT-MK. “We have successfully tested a prototype for DRDO in association with NPOL. The DRDO project is worth Rs 20 lakh. Another work amounting to Rs 8 lakh was done for a virtual reality company,” he said. The projects in the pipeline are a prototype that can carry a payload of one kilo. “Two other projects for prototypes that can carry five kg and 24 kg payloads too are underway,” he said.

The team is expecting a future investment of Rs 10 to Rs 15 lakh. “We want to use the domain efficiently. Also, we have been asked by Walmart to use the drones to help solve their space management issues,” he said.

In a Nutshell

A day in a Chennai cocoa farm

Raw Chocolate Plant
Raw Chocolate Plant

Read on to discover where your chocolate comes from,

Nagappa and his team of three usually have their hands full with cocoa pods. It is the fag end of harvest season, after all. But today, their attention is elsewhere.

Heavy showers — that were barely felt in Chennai city — hit hard on the 30-acre farm 60 kilometres away along the Tirupati highway, felling a 20-year-old mango tree near its entrance. “The farm owner, Vijay Kumar sir, is on his way from the city,” he says. His visit is a rare occurrence, so Nagappa, Kamalakanni, Meghala and Panjo are now tackling the fallen tree, hacking its parts and clearing it away. Of the 249 mango trees here, this is one they will miss everyday. Under its shade, on a rare clear patch of land, is where they spend a significant part of their day, shelling (or hacking, more like) cocoa pods.

Once he has a minute to spare, Nagappa demonstrates: He takes a plucked pod and places it on an upturned metal basket. Holding the curved, rolling fruit still with one hand, he picks up a thick, heavy stick with the other, and gives it two sharp whacks. A crack appears along the shell and he prises it open, to reveal an interior vaguely similar to that of a custard apple. It’s larger, of course, and the beans — covered in sticky sweet, white pulp — stick together in a cluster much longer. He plucks out a single little bean to taste: bite into it, and you will see a bitter, deep purple substance. That is the cocoa the world worships.

Harvest time

The farm used to have 3,000 cocoa trees. “Vardah felled many of them: we now have about 2,500 left. But we will also be planting 500 saplings brought in from Andhra,” says Nagappa. Each tree produces about 50 pods a year, a majority of them between April and May. So another part of the team’s work involves visiting each tree as often as they can, to pluck the pods before they get overripe. And how can they tell when they are just right? “You have to know each variety like your child, or they might fool you with their appearance,” smiles Nagappa. Of the four varieties, some turn helpfully yellow when ripe for plucking. Others need their harsh surface scratched by nails before they show their true colours. Yet others don’t change colour at all, “and we pluck them anyway. Especially now, with just a few weeks left in the season, they’ll invariably turn out to be ripe,” says Nagappan confidently.

He should know: he is incharge of not only the farm’s cocoa trees, but also its 250 mango trees, 400 sapota trees, 700 coconut trees and even more gooseberry (amla) trees. Some of them grow in isolated patches while others help each other out. The cocoa, for instance, can only grow in shade, and hence is planted under dense clusters of coconut trees. Large leaves of both stay untouched on the ground when shed, to fertilise the soil together.

“We start working at 8 am and wrap up by 5 pm,” says Kamalakanni, who lives on the farm with her husband while the rest go home. “We water the young trees, check for diseases and bugs, and pluck whatever is ready.” It’s not easy, when you have thousands of trees.

Once the cocoa pads are shelled, they move to fermentation. Among other clients, the farm has tied up with bean-to-bar chocolate maker Cocoatrait, which has been giving them tips on identifying different varieties, how to pluck them so as to speed up the next batch of fruit, and how to ferment. “All these factors play a big role in the final flavour of the end chocolate, so we are happy to tie up and work with farms directly,” says Nitin Chordia, founder of Cocoatrait, who has also done consulting works for farms in Andhra Pradesh and Kerala.

Inside a closed room, pungent with a sweet stench like that of cheap wine, stands a little wooden box lined with banana leaves. It is filled to 75% capacity with cocoa beans, left to heat and ferment by themselves. The box perforated with small holes to stick a thermometer in, and is unpacked regularly to shift the beans around, ensuring equal heat throughout.

But that process takes time. As the harsh afternoon sun teases them from behind wisps of cloud, the workers take a break where the shade of the mango tree once used to be: scraping coconut from its shell and popping it in their mouth. Behind them is strewn a carpet of brick red cocoa shells.

Coimbatore :

An engine that runs on distilled water and even rain water? Stuff of dreams, you say.

No, insists a city-based mechanical engineer. Sounthirarajan Kumarasamy claims his engine will break down water and be propelled by hydrogen. And emissions, how about oxygen for a change!

His prototype, he claims, can be used in all vehicles from two-wheelers to trucks.

Sounthirarajan says the Indian government granted him a patent in November 2018 for his Super Sonic Hydrogen IC Engine, which he says he will debut in Japan.

The class XI dropout from Kangayam in Tirupur did the research for his project at the District Central Library in Coimbatore. “During the initial years, I used my old defunct jeep to learn about the hardware,” said Sounthirarajan, who hails from a farming community.

“Utilising the thermal losses in the engine, hydrogen could be burned that helps vehicle run. I have currently designed the engine with the capacity of 100cc, which could emit oxygen while it’s running. All the tests were successful,” he told Express.

Sounthirarajan established his company in 2010 and says he has opened a branch in Tokyo a few months ago. He also runs an incubator cell at the PSG-Science and Technology Entrepreneurial Park (PSG-STEP), Coimbatore. He has been ‘working on designing this machine’ for the past ten years.

He said, “With my invention, you can run your vehicle for 200 km with just 10 litres of distilled water. We had even tried running the engine with rainwater and it bore fruit.”

Sounthirarajan now plans to organise an international summit in Kyoto soon to showcase his work to potential buyers from across the world.

He says that his machine could be sold for Rs 1.5 lakh for a four-wheeler. If it’s a two-wheeler, then he says the price will be around Rs 65,000.

His colleagues Prakash, Sathish, and Chandrasekar assisted him.
