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 the conservatives and white supremacists responded to “Black Lives Matter” movement

The civil rights movement in America labelled “Black Lives Matter”, which erupted after the murder of George Floyd by a uniformed officer has been going in full swing. The event of Floyd’s death triggered a mass reaction against the state violence in which black people are abused without any accountability on the police’s part. A few of the protests have been demanding the defunding of the police department, that the police force should be dissolved.

Many protests are peaceful protests, but there have been instances in which the protestors use violence to express their sentiment. Such protests have received a lot of backlash; Donald Trump, the president, said that “these THUGS are dishonouring the memory of George Floyd” and that “when the looting starts, the shooting starts”. He also mentioned that he would send the National Guard to “get the job done right”, in context of his perceived lack of leadership in Minneapolis where Floyd was killed, and consequently, where the protests were taking place. The tweet with the slogan “When the looting starts, the shooting starts” has since been censored by twitter, which gave birth to another controversy.

Trump also blames the riots on Antifa, which is a terrorist organisation according to him, the name of which stands as a short form of anti-fascist. The organisation is a group of leftist activists who protest against an expression of what they find xenophobic, racist or sexist and fascist, claiming that such expression would suppress minority voices. There is no defined hierarchy or membership process, though it has been claimed by the group that it is secretive and is organised into autonomous local cells. In some reports, though, it is categorised as a far left militant organisation which believes in direct action rather than peaceful protests.

The police force in Minnesota believes that there are white supremacists attending the protests to agitate the protests and incite chaos. The Brookings Institution characterized the same as accelerationism, in which people incite chaos to destroy social order, so that in a highly polarized society, people would take their side. In the same vein, it has been reported that a white supremacist channel on Telegram incited followers to engage in violence and start a second civil war by shooting into the crowd. Franklin Graham, an evangelical pastor, has said that the idea of dismantling the police departments “has to be one of the most irresponsible ideas” that he’s ever heard. He says that the police are what stand between “us (the citizens) and total anarchy”.

An UK Member of Parliament told one of his constituents that while racism is a cancer, and I am glad the perpetrator is on a murder charge. Nevertheless, looters, arsonists and rioters have it coming.” While a number of celebrities have been showing support for the Black Lives Matter protests, the former Miss Universe Malaysia Samantha Katie James used instagram stories to say that the protesters who are angry over the murder of George Floyd are “foolish humans”, and that the black people chose to be born as colored people in America. She also said that the brutality should be taken as a challenge and that “the whites have won”. When asked to clarify what she meant by saying that the Black community chose to be born as coloured, she said that their soul chose where and how they were born.

The people are responding in many different ways to the news. On a Brietbart report on Samuel L. Jackson expressing his views in support of the protests, there have been comments which say that “Floyd was a criminal and he was high on drugs and that he was not killed by asphyxiation he had a heart condition.”(sic) or “When da White people start rioting? We are still the majority, and it would really stir up the fudge. These a****ts think they are getting away with something, but only because the silent majority has yet to speak… and act.” (sic).

It seems that George Floyd’s unfortunate death has brought out not just the simmering anger of the long black community in open but also unmasked the outright white supremacists as well as their apologists.
