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.

How can Science Communication save the day

Pierre-Simon Laplace, an exemplary French Mathematician, once quoted: “It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit.

I intentionally aimed to start this article with a quote by an excellent western mathematician, because we Indians need validation from westerners. We are quite capable of making high strides in science, technology, and innovation, but there is a lack of vision; lack of confidence.

The newly Independent India of 1947 had a vision: a vision to transform into a developed country using scientific interventions. We had some great revolutionaries who worked tirelessly to shape a bright future for our country. Dr. Vikaram Sarabhai founded the Indian Space Research Organization (ISRO) while Dr. Homi J Bhabha, the Department of Atomic Energy (DAE). There was a time when Dr Sarabhai convinced a Church to give land for a rocket launch station.

When India became Independent in 1947, people just wanted to earn enough to survive in the rapidly changing, bitter conditions. Today, when we are one of the economies of the world, we are fighting over temples and mosques, trying to rename cities, and dream of resurrecting some thousands of years old notion of India, the quest for scientific temperament is lost somewhere along the way.

Over the years, India’s spending on Research and Development has increased significantly in overall value but its share in GDP has remained stagnant at 0.6-0.9%. The research being done in India is quite good if we compare it to the funding received. However if we compare it with the developed countries, the gap is phenomenal.

India’s space program, atomic energy program, development of supercomputers, or development of light combat aircraft- Tejas shows that Indian scientists have given great results at a fraction of the costs of their western counterparts. Still the allocation of funds for the scientific research is well short of what is required to catapult India into the league of developed nations.

If we deep dive into the probable causes of underfunding of Indian scientific research in spite of giving good return on investment, it boils down to the lack of awareness about the same among the larger public as well as policymakers. As we know that the best way to receive funding is to create awareness about a valuable product. We don’t lack products; we lack dialogue. Science is hardly ever reported in India. It’s rarely a point of discourse. When there is no discourse around something, it leads to a lack of interest. This is also driving away the bright students from pure sciences to the technology and management which is more remunerative.  

Another issue that sprouts up from lack of discourse is the lack of belief in science. We have seen how in India, many public figures started spreading home remedies and terrible unchecked solutions like the benefits of Cow Urine during the COVID outbreak. The news channels, instead of discussing facts, talked about conspiracy theories. These news channels sometimes invited scientists for talks, but eventually, ruined everyone’s time for their TRP by asking them about the conspiracy theories.

Science literacy can reduce these pseudoscience tactics. Indians extensively believe in spirituality which is good for personal motivation and values, however the unscrupulous elements have often used it to spread misinformation and personal gains. It's imperative that we take a stand to promote scientific thought, and this is not at all an arduous task. Instead, the solution is straightforward: We need to communicate.

We need our own Neil DeGrasse Tysons, Carl Zimmers, Carl Sagans who can communicate with the common people about scientific development, in a simple language. This will help us to kick start our journey towards the Golden Era of Science without a baggage of baseless beliefs, pseudoscience, and untested products.
