Anthony Camu, a final year Industrial Design and Technology student at Loughborough University is making headlines with his latest creation of a handheld robotic guide dog. This will be a great help to those people with visual impairment who might find it difficult to accommodate an actual guide dog in their homes.

The robot is named after the Titan goddess of light, ‘Theia’ and is shaped like a virtual gaming controller, which enthused Anthony to create this masterpiece in the first place. Theia listens to the user’s voice to lead them to their desired locations.

If the user has to go to some address (for eg. House number 4, 56th Street, Greenville Residency), they have to say ‘Hey Theia take me to House number 4, 56th Street, Greenville Residency*’. It will then process the actual data available online, like traffic density, and program the most secure route for the user to follow, quite similar to how GPS or satellite navigation works in our cars.

All the information is then communicated to the user via a machine built inside it, called a control moment gyroscope which uses the mechanism of ‘forced feedback’. These are used in spacecraft and their main function is to help in orientation purposes of the spacecraft, or in controlling the ‘spacecraft attitude’ using electric power.

This tiny built-in gyroscope physically moves the user’s hand in the direction they are supposed to go, thus giving them a feeling of being led by an actual guide dog. “The main intention was never to replace guide dogs, but instead to provide an alternative means of giving enhanced mobility options to visually impaired people” says Anthony Camu.

According to Mr. Camu, Theia will also be helpful in confronting challenging interactions like elevators or shops. While crossing a busy street, it will tend to ‘push back’ the users, cautioning them to be more sentient about their current surroundings. Moreover, Theia is quite pocket-friendly, costing about one-tenth the price of a real guide dog.

This tool will also contribute in imparting a sense of belonging and reduce the constant mental hassle and anxiety faced by the visually impaired population of the world. Since they are unable to assess their surroundings, it limits their outdoor movement. This will help them move in the outdoors more often and reduce stress while navigating the traffic on the road.

Anthony has created and experimented with many prototypes of Theia and some work is still needed to correct a few issues before the final launch his product in the market

However, he concluded that Theia has a promising future and it requires just a little more testing and research.“I know this is a grand vision, but I hope people can see the positive effects Theia could have on the blind community” he states.

COVID-19 and its impact on the Agri Economy of Punjab

The COVID-19 pandemic has hit the agricultural economy of the Indian state of Punjab really hard. Punjab’s paddy farmers have traditionally relied on migrant agricultural labourers who are mostly natives of the state of Bihar and Uttar Pradesh. Due to the pandemic, a large number of migrant labourers have returned to their native place causing a massive shortage of farm workers in Punjab.

Its impact became more severe as the paddy transplantation period was already around. Gurbachan Singh, a local paddy farmer told news agency ANI, "There is a shortage of labourers as the government sent back the migrant workers without proper planning."

The shortage of migrant workers forced the farmers to rely more on the local labourers. The local labourers used this opportunity to demand more wages which has resulted in almost doubling the labour cost. The migrant labourers used to charge around ₹2500 per acre for sowing paddy while the local ones were demanding ₹4000 per acre for the same work.

The  village panchayat (Local village council) tried to fix the labour charges of ₹3,000 per acre which did not go down well with local labourers. This caused a dispute which even resulted in a clash between labourers and farmers where the shots were fired as well.

The labour shortage does not appear to be ending soon as most migrant labourers are not willing to come back. Viresh Kumar, a labour contractor from Sonbarsa in Bihar’s Sitamarhi district who supplies workers to paddy farmers in Phagwara, told ThePrint, “Workers from Bihar and UP either don’t want to come back to fields in Punjab or they want farmers or us to bear the cost of bringing them back, which is a very expensive and complex procedure now. Due to the lack of sufficient number of regular trains, the cost of bringing a single migrant to Punjab is around Rs 3,000 to Rs 4,000 per person.”

The shortage of cheap labour has forced the local farmers to start looking for some alternative which could maintain the economic feasibility of farming.also provided some benefit

Agricultural Secretary of Punjab government, KS Pannu noted that some of the farmers have started employing new technology to cope up with the labour shortage. "Farmers have sown paddy at around 5 lakh hectare land with Direct Seeding of Rice technology this year. Some farmers, however, shifted back to the puddling method for cultivation as they could not adapt to the technology," Pannu told ANI.

Manpreet Ayali, a member of Punjab State Legislative Assembly, and a wealthy farmer, says that this labour shortage is a blessing in disguise for the farmers as it would make them more self-reliant, rather than depending on labour for the transplantation season.

The shortage of cheap migrant labour has forced many farmers to cut down the area of paddy cultivation. Experts believe that due to the reduced area of transplantation the groundwater levels might improve in the state which tops the country in over-exploitation of groundwater reserves.

It is still too early to give a definite verdict on the long term impact of the COVID-19 on the agricultural economy of Punjab, but in the short term it is nothing short of a disaster for the local farmers.
