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.

Expat Exodus In The Middle East

The COVID-19 pandemic has hit people and economies worldwide, sparking a global recession and financially destabilising millions of people. In the Middle East, dipping oil prices have only worsened the threat to the economy. Businesses are shutting down, and many are trying to survive by cutting the salaries or laying off of workers. Large segments of the workers in these countries are expatriates, and many have struggled to make ends meet as unemployment soared.

The development of the Gulf countries has always been intertwined with their large expat populations. These workers are often vital to the economy, not just as part of the workforce but also as consumers by enabling successful malls, restaurants and other forms of recreation and tourism. Countries like Saudi Arabia gain valuable non-oil revenue in the form of increased Value Added Taxes (VAT) and by imposing a monthly fee on migrants who want to sponsor family members.

Many of these workers are from developing Southeast Asian countries such as India and Pakistan, and contribute greatly to their home country’s economy in the form of remittances, i.e sending money back home. Those who are facing unemployment or salary cuts are eager to be repatriated, especially since in many Gulf countries visas, rent, and even phone lines are linked to jobs, and expats have little to no social safety nets to fall back on.

Panicked” Indians applying to go back home crashed the Dubai aviation ministry’s website for applications in the process. The consulate says it has received around 200,000 applications for repatriation of expats from as many as 12 countries.

For some, closing businesses are forcing them to go home. For others, the cost of education is the major concern. The Emirates group, Uber’s Middle Eastern counterpart Careem, and hotels are some of the few major employers considering laying off large portions of their staff or reducing salaries.

Dubai has been one of the hardest hit, as expats form an estimated 92% of the population. Dubai based movers estimate that they’re getting up to seven calls a day to ship belongings abroad. It is extremely hard to gain permanent resident status in countries such as the UAE, and the costs of living and education are quite high and often provided by employers, which has made leaving the only option left for many laid-off workers across all fields.

The UAE has tried to offset the damage by granting automatic extensions to expiring work permits, waiving of work permit fees and fines, and providing interest-free loans and repayment breaks.

Meanwhile, governments in Kuwait and Oman are trying to mould the exodus into an opportunity to boost local employment. On the other hand, the Saudi Arabian government has been criticised for not taking enough measures to protect the local workforce.

While the Gulf countries have been trying to decrease their dependence on oil wealth and foreign workforce, it is not something that can be accomplished soon, especially given the great dependence of the Gulf economies on both those factors.

There is still too unavoidable a gap between the current skill of local workers and the training needed to compete with foreign professionals, making it hard to simply employ domestic workers in place of foreign ones. The pandemic, however, might not leave much of a choice.
