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: Trump, Antifa, and the Anti-Racist movement

As massive protests following the passing of George Floyd kept on shaking the United States. President Donald Trump tweeted on 31st of May that far-left group Antifa was the one behind the violent riots and he would designate it as a terrorist group. He said, “The United States of America will be designating ANTIFA as a Terrorist Organization.” This assertion was repeated by the US Attorney General William Barr as well.

Antifa, short for anti-fascists, is an amorphous movement and not an organization as Trump labels it to be. They tend to be on the left of the U.S. political spectrum, many describing themselves as socialists, anarchists, anti-capitalists or communists. Antifa, according to many commentators, is just a decentralized collection of individual activists who mostly use non-violent methods to achieve their goal, which is to resist the spread of fascism. They track people who spread racist hatred and fascist ideology through on-ground events, traditional media, or social media and use cultural forms of art like drawing, music, film screenings etc. to spread the message of inclusivity. There are more militant anti-fascist groups as well, who mostly engage in non-militant activities but are willing to use more confrontational tactics at times as well. 

This is not the first time that Donald Trump has criticized Antifa to shift the focus away from racial discrimination faced by the black community in USA. In this instance as well President has tried to portray the protestors and looters with a vague phrase “radical-left bad people” and invoking “Antifa” to represent the whole of leftist militant groups which are bound more by belief than by any organizational structure.

Taking a cue from President Trump, many officials, conservative commentators and white supremacists started blaming Antifa for using the “Black Life Matters” movement to indulge in violence and undermining the government of the USA. Mr Trump’s national security adviser, Robert C. O’Brien, had also blamed such activists during his appearances on CNN and A.B.C. News. Mr O’Brien said the F.B.I. needed to “come up with a plan” to deal with Antifa. John Guandolo, who was in the FBI for 13 years, went a step ahead and claimed that Antifa and “Black Life Matters” are communist organizations, who are planning to overthrow the US government. He also praised President Trump for calling Antifa a terrorist organization and lamented that the FBI are unaware of its plan. Fiona Moriarty-McLaughlin, a journalist at the right-wing publication Washington Examiner, re-posted a video purportedly depicting "Paid #Antifa thugs" vandalizing the store — even though there is no evidence to suggest that the vandals were members of the movement.

The FBI and local law enforcement agencies have aggressively pursued charges against rioters, looters and others accused of havoc. However there is no evidence of any involvement of organized violence by Antifa or any other left-wing group. The most serious case that has emerged in federal court involved three men in Nevada linked to a loose, national network of far-right extremists advocating the overthrow of the U.S. government. They were arrested on May 30 on charges of trying to foment violence during Black Lives Matter protests. There are many instances when white thugs were seen vandalizing which blacks feared could be used against them.

The invocation of Antifa by President Trump during the “Black Life Matters” protest is conveniently used by the conservative commentators and white supremacists to somehow shift the focus away from the deep rooted racism in the USA to the violent actions by some protesters during the “Black Life Matter” protest.
