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.

Suppressing the Minority Voting: An effective discrimination tactic of the US Conservatives

The recent protests over George Floyd’s death and reactions of the conservatives against the protest laid bare the systemic injustice and oppression faced by the people of color in the USA.

The other, albeit invisible form of discrimination perpetuated by the conservative political establishment in the USA is “Minority Voter Suppression”.

Though it may seem improbable that long after the Jim Crow laws are junked and Civil Right Laws are in place, the effort to disenfranchise the Black people is still going on.

The major piece of legislation which protected minorities from electoral exploitation was the Voter Registration Act which underpins the basic ideal of a universal adult franchise by specifically addressing and combating voting discrimination.

To ensure the representation to minority communities, this act mandated that “At-Large Elections”, where the whole of the jurisdiction elects all of the city council, were replaced by the single member districts in which each community selects a person to represent them in the city council.

It was also prohibited to draw the voting district in such a way that  minorities could be clubbed in only a few of the districts. It was also made mandatory for those states which have a history of discrimination to get pre-clearance from the justice department before changing their voting laws.

This law, however, lost its power in a process which began in 1980. In 1980 the Supreme Court ruled that at-large elections were not unconstitutional, on their own. In 1995, the Court began restricting the construction of majority minority districts on grounds that it segregates people on the basis of race.

In 2008, the court ruled that a photo voter ID law in Indiana was constitutional and was in state interest to protect against voter fraud (research shows that photo voter IDs provide disincentive to vote for people of color). The voter ID law requires the voters to have a government-issued photo ID to cast a ballot.

In 2013, the Supreme Court scrapped the part of the law which stated that some states (which had an alleged history of discrimination) needed federal preclearance in any changes of their voting laws, meaning that the state laws would need approval from the federal government before being put into practice. This was done so citing that the methods which determined discriminatory states were invalid.

All of these slowly chipped away at the laws, and especially the 2013 Shelby County vs Holder case which led to a host of issues whVoter Suppression is Still One of the Greatest Obstacles to a More Just Americaich directly/indirectly keep a significant proportion of minorities from voting. Few of such actions are closure or relocation of precincts in majority black areas, purge of minority voters from the voter lists, and elimination of Sunday early voting days which are preferred by black voters.

There have been attempts to restrict registration drives in Tennessee on the basis that many of the forms were incomplete.

There have also been laws enacted which needed people to participate regularly in elections to keep their voting rights and reply to a letter sent to their residence, which makes it difficult for Black and Hispanics due to obscure areas and the fact that they’re half as likely than other people to get a day off work to vote.

The governor of Georgia, Brian Kemp, has been accused of using intimidation tactics to scare minority communities.

In Texas, the acting secretary of state said that he had a list of 95,000 non-citizens who were registered for voting in the state, and 58,000 of them had already cast a vote. That claim was proven untrue when it was noted that there were tens of thousands of people who were naturalized citizens.

In many states, felons are not allowed to vote even after they have served their sentence, and in Florida felons are allowed to vote only if they have paid an array of fees after serving their sentence, which sets an economic bar on their ability to vote.

This is evident that forces working against the equal rights for the minority communities are still working at full force to reverse the gains of civil right movements. The fight for the unhindered voting rights for the minority communities in the USA at the social, political, and judicial front will continue in the foreseeable future.
