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.

India’s neighbours drifting towards China: Has PM Modi’s “Neighbourhood First” policy failed?

Back in 2014, when BJP came to power in India under the leadership of Narendra Modi, he invited the heads of government from Nepal, Bangladesh, Pakistan, Afghanistan, the Maldives, Bhutan, and Sri Lanka to his swearing-in ceremony at the Rashtrapati Bhavan.­ The move set the tone nicely for Modi’s “Neighbourhood First” foreign policy and was hailed by experts and critics alike as a positive step towards bolstering regional connectivity and improving cross border relations. Cut to 2020, and the ongoing China-India conflict has exposed plenty of problems for New Delhi regarding its relations with its neighbouring countries, particularly, Pakistan, Bangladesh, Sri Lanka, and Nepal.

In recent days China has increased its investments in Asia and beyond even as India and the West have watched from close quarters. Most of the investments have revolved around Chinese President Xi Jinping’s Belt and Road (BRI) Initiative , which aims to create a Sino-centric global trading network and sphere of influence. The BRI initiative is a matter of concern particularly for India because of the China-Pakistan Economic Corridor (CPEC) that is perhaps the most important project under the BRI initiative.

India has, traditionally, played a dominant role in economic and political matters concerning most of its smaller neighbours. However, with the BRI initiative, China gradually built up its political ties with countries such as Nepal, Sri Lanka, and Pakistan, while India’s relations with these countries have become less cordial in recent years. Nepal, Sri Lanka, and Bangladesh, who were once considered allies to India appear to have tilted in favour of China.

The changing nature of India’s and China's relation with India’s neighbouring countries was evident in the silence of these countries when there was a serious flare-up on the India-China border. It is important to note that every South-Asian nation except Bhutan has signed on to China’s BRI. Bhutan is still following India’s lead in not joining BRI due to its own border dispute with China, for which India’s support is essential.

Nepalese PM KP Oli had called Indian PM Narendra Modi, on 15th August, India’s seventy-third Independence anniversary. A statement by India’s Ministry of External Affairs stated, “‘The leaders expressed mutual solidarity in the context of the efforts being made to minimise the impact of the Covid-19 pandemic in both countries.” However, in June 2020, the Nepalese Armed Police Force fired upon a group of Indian citizens at the India-Nepal border, killing one person and injuring two others. A third Indian who had been detained was released later. The move came in the aftermath of the Nepalese Parliament declaring the Indian territories of Limpiyadhura, Lipulekh and Kalapani as a part of Nepal.

Historically, India and Bangladesh have maintained close ties with each other. Modi’s rise to power in 2014 had no effect as Bangladesh’s PM Sheikh Hasina continued to maintain relations with India. In June 2015, when Modi visited Bangladesh 22 bilateral agreements were signed, including the resolution to a border issue that had existed since 1947 through a successful land boundary agreement (LBA). India also pledged $5 billion worth of investments in Bangladesh. When Sheikh Hasina visited New Delhi in April 2017, a civil nuclear tripartite pact was signed between India, Russia, and Bangladesh. Under the pact India will play an important role in establishing a nuclear power plant in Bangladesh. Even as late as March 2019, Narendra Modi had launched four projects in Bangladesh.

However, India’s relationship with Bangladesh turned sour post August 2019, when the BJP government implemented the NRC in Assam, a north-eastern Indian state. The process of NRC was meant to identify illegal immigrants from Bangladesh. The 1.9 million people left out in the Assam NRC were a cause of concern for Bangladesh owing to the fear of a sudden influx of people forced out of the Indian state. Bangladesh thus turned to China under its “look East” policy in a bid to reduce its dependence on India. China replaced India to become the top trade partner of Bangladesh in 2015 and has provided assistance to Bangladesh through the BRI via 27 agreements signed on Xi Jinping’s visit to the nation in 2016.

“China is behaving how emerging superpowers generally tend to behave—they try to flex muscles and project power—all of which China is trying to do at the moment," says Happymon Jacob, associate professor of disarmament studies at Jawaharlal Nehru University (JNU). “When that happens, states around that emerging power will either stand up against it (like India) or jump on the bandwagon (like other smaller south Asian countries)."

While China continues to make rapid strides, India is left to wonder as to how to deal with this apparent crisis surrounding its neighbouring countries. Modi’s neighbourhood first policy has certainly failed to deliver the promises it made and relations with most neighbouring countries have worsened over the past six years. New Delhi has missed out on several economic gains that would have strengthened ties with neighbouring countries and thereby would have helped to counter the growing Chinese influence in the region. It remains to be seen as to how India decides to get over this tricky situation and improves its ties with its neighbouring countries.
