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.

COVID-19 in Iran: Fighting pandemic while facing US sanctions

After backing out of the nuclear deal with Iran in 2018, the United States had toughened the sanctions on petrochemical trade and other vital sectors of Iranian economy. The Iranian government is claiming that those sanctions are heavily affecting their ability to act against COVID-19.

These sanctions forced the Iranian government to significantly change infocus from curbing the spread of infections to stabilizing the economy.  There have been some restrictions but no lockdown imposed on the movement of people as the lockdown would further weaken the economy. Also, a lot of pharmaceutical companies aren’t willing to trade with Iran because of the fear of getting caught up in secondary sanctions, even though the US governments deny any restriction of the same. 

All of this has led to a global outcry against the sanctions. The United Kingdom is pushing the US to ease the sanctions because they believe that the hospitals in Iran are badly overstretched. The UK tried to provide direct support to the country via WHO, but Iran refused any help that didn't come with the lifting of the sanctions. The United Nations High Commissioner for Human rights, Michelle Bachelet, has urged the global community to rethink the existing sanctions on countries like Iran in the light of the current pandemic. The United States also offered humanitarian assistance to the state but was rejected by the Supreme Leader Khamanei, who declared the US as being charlatans and liars, and said that a wise man should not accept medicines from a country alleged of creating the virus. Russia, China and some other medical and rights groups have been urging the Trump administration to lift the sanctions. Over 21,000 lawyers and legal experts in Iran have signed a statement declaring that the US sanctions on Iran are anti-human. On the 26th of March, the US imposed even more sanctions, on more than 17 entities. The sanctions were announced a day after the family of a retired FBI agent claimed that the agent had died while in custody in Iran; two days after Ms. Bachelet made her statement on rethinking sanctions.

The crisis has touched most corners of the country, but it is most severely impacting the poor and working class. While it is older men who are dying in the highest numbers, the economic impact especially hurts women, who are most liable to lose work, and shoulder increased duties, looking after sick relatives and children staying home from school. Iranians’ purchasing power has plummeted in the past two years, as the mismanaged economy shuddered through Donald Trump’s withdrawal from the nuclear deal and the re-imposition of US sanctions. As Nahid, a women’s rights activist put it: “When people met this virus, their nutrition was already poorer, their immune systems were weakened, and many were already unable to afford health care.” Charities and private sector groups are joining together to raise funds for importing equipment and other medical supplies from China to set up facilities of COVID-19. However due to the sanctions it is becoming difficult to move money from Iran to any other country.

Arshi Tirkey, a Junior Fellow with Observer Research Foundation has put quite aptly: “It is true that political instability, corruption and economic mismanagement in Tehran have aggravated the issue; and likewise, this calls for governance reforms and financial transparency initiatives in Iran. But this is not the sole reason for the scarcity of medical equipment and the condition of health infrastructure in the country today. Sanctions remain a central impediment to improving Iran’s capacity to respond to the pandemic.”
