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.

With a new Anti-Terror Act: Philippines take another step towards authoritarianism

On July 3, 2020, President of the Philippines, Rodrigo Duterte signed a new Anti-Terrorism Bill, which was rushed through the houses of Congress without appropriate discussion, and has amassed protests and disapproval within the nation and abroad since its draft was first announced.

The Confederation of Lawyers in Asia and Pacific (COLAP) has raised concerns that anti-terrorism bill of the Philippine government is “violative of human rights and the due process of the law.” It's statement opposing the the bill stated following concerns with the bill:

  1. It punishes suspected individuals for organizations who are proscribed as terrorists and that the very broad and vague definition of terrorism under the bill poses danger to the basic freedoms of the people.
  2. The suspect’s right to due process of law is virtually denied and the presumption of innocence until proven guilty by a court is virtually negated.
  3. It enable the President-backed Anti-Terrorism Council to label any individual or group as a terrorist “without the opportunity of being heard.
  4. Any member or sympathizer of a proscribed organization is punished as a terrorist even if he or she does not actually take arms against the government.
  5. The bill encroaches on one’s privacy as it gives the government access to personal and bank information and freezes bank accounts and assets.
  6. The bill violates the sovereign rights of states and the internationally mandated norm that criminal jurisdiction is confined to the territories of a state, citing its extraterritorial nature.

Hundreds of protestors took to the streets of Manila protesting the bill on 27th July when President Duterte gave his annual State of the Nation address. While it is true that the has nation faced the threat of terrorism in recent years, it is also agreed upon that Duterte’s response has been perhaps equally brutal.

This bill was also criticised by the Christian religious organisations which issued a joint declaration on this law. They stated “We are bothered by the broad and vague definition of terrorism and terrorist. It can include acts of dissent, free speech, right to assemble, right to organize, freedom of belief, among others. By such a broad definition it is open to abuse and misuse.”

An opposition Congress member, Edcel Lagman and two lawyer groups of Philippine approached the Philippine Supreme Court and asked it to strike down the new anti-terrorism law, or parts of it, as they called it unconstitutional for infringing on civil liberties.

The Philipino American Student Association (FASA) also denounced the new anti-terrorism law in its Instagram post which stated, “FASA sa UW denounces Duterte’s signing of the Anti-Terrorism Bill to which its terms do nothing to resolve the true terrorism in our nation and instead conducts an outright assault on the freedom of speech from our people living on the motherland and even Filipinx abroad,”

International Human Right organisation, Amnesty International’s Asia-Pacific Regional Director, Nicholas Bequelin, in response to this law said, “Under Duterte’s presidency, even the mildest government critics can be labelled terrorists. He further stated, “This law’s introduction is the latest example of the country’s ever-worsening human rights record. Once again, this shows why the UN should launch a formal investigation into ongoing widespread and systematic violations in the country.”

Prior to this, Duterte’s ‘war on drugs’ received global scrutiny, especially for the numerous extrajudicial killings that have occurred since he came to power and the effect of this aggressive policy on the poorest citizens of the nation.

Apart from this, he has also repeatedly voiced opinions in favour of martial law and silenced news media that spoke against him. But he seems to be encouraged largely by his own people, among whom Duterte continues to be popular.

Many have called Duterte the ‘revival’ of authoritarianism in the small Southeast Asian country, which has only recently seen some semblance of democracy after years of dictatorship under Ferdinand Marcos (of whom Duterte was a close family friend).

The Philippines is walking a thin line between fascism and democracy, and which side it ends up on depends not only on the actions of its government, but just as much on the actions of its people.
