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.

Black Lives Matter: Solidarity protests in Western Europe

The killing of the African-American George Floyd in the hands of Minneapolis police commanded world attention. It witnessed Pan-American protests against police brutality and racism. Countries across the world have stood in support of these protests against racial violence. These protests in America have triggered a number of protests across Western Europe to localise them and condemn racism in their own countries.

Protests against racial violence and police brutality drew large numbers across European capitals and other prominent cities as well. Paris protests alone saw an estimated 20000 people near the Eiffel Tower who protested against the death of George Floyd. These protesters tried to localise the issue of racial violence and police brutality by taking up the case of Traoré, a young black man whose family claims that he died due to suffocation under police custody at Persan (north of Paris) in 2016. These protests have been going on consistently for over a week. Despite the police ban on demonstrations in Paris due to the risk of COVID-19, the demonstrations couldn’t be curbed. Parallel protests were also reported in other cities of France like Lyon, Rennes and Marseille.

Berlin also has been sustaining its ‘Black Lives Matter’ protests for over a week. Demonstrations were held in other German cities such as Cologne, Frankfurt and Dusseldorf. The Bayern Munich footballers wore T-shirts with slogans that read ‘Red card against racism- Black Lives Matter’ in their match against Leverkusen to raise awareness against racial violence. Various German activists believe Floyd’s death has not only triggered anti-racist protests but also multiple questions regarding equitable distribution of resources and representation of diverse races that co-habit in Germany.

In the United Kingdom, too, despite the COVID-19 risk, a large number of protestors stood in solidarity with the U.S protests. In Bristol, demonstrators pulled down the statue of slave trader Edward Colston on 7 June, 2020. Even though these protests were against racial violence, the chords of the protests mainly struck with issues of blacks during COVID-19. British government data showed that blacks living in British were four times more likely to die from COVID-19 as compared to whites. This discrimination by the virus can be attributed to the institutionalised nature of racism and the lack of equitable access to resources for minorities living in Britain.

Protests were held widely in Spain. The U.S embassy outside Madrid has become one of the hotspots for protestors to gather. Hundreds gathered to mourn the death of Floyd and observed silence for him. The city of Budapest too observed silence and chanted songs outside its U.S embassy.

European media has also played a key role in actively condemning Trump for his actions of using military force to tackle the protests. While the French Newspaper Le Monde in its editorials has dubbed Trump as ‘President of division’ the Spanish newspaper El Pais’s headlines read ‘The U.S. Faces Its Worst Racial Conflict in Half a Century’. Trump’s actions to use federal force and active duty military personnel have made the European media to cover the protests more extensively. Newspapers coupled with social media have acted as catalysts in spreading the cause of the protests at a much faster rate.

Floyd’s killing sparked protests against racial violence and systematic racism around the world. However, it resonated at a deeper level with Western European countries primarily due to their rising number of immigrants from African and Arab countries. These countries, for decades, have struggled with accommodating these minorities equally with the mainstream population. The approach to localise these protests has helped to not only denounce racial violence in America but also in their own home country. The nature and extent of these protests have pointed out that governments no longer have the luxury of gradualism and have to instead take up swift actions to eliminate institutionalised racism and police brutality.
