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.

Forced Uyghur labour in China: Getting the World attention now

Since 2017 nearly a million ethnic minorities, mostly Uyghur Muslims from the far Western region of the Xinjiang province of China, have been put in  detention centres. The detainees in these camps are forced to renounce their faith and, in some instances, have been subjected to torture.

The Chinese government has termed the program as a combat against “religious extremism” even as it detains members of ethnic minorities from the region and sends them to the so-called “re-education camps”. The experts however believe that these people have been thrust into a systematic program of cultural genocide.

This campaign now appears to be proceeding towards a new direction wherein the Uyghur detainees are being shipped across the country for forced labour in factories.

As per the government officials, these “trainees” have all “graduated” and are being given employment in the form of factory labour to lead a better life. While China has made this their sole criteria to defend the program, there is mounting evidence that suggests that the Uyghurs are being subjected to forced labour and are not allowed to visit their families in Xinjiang.

According to a report by the Australian Strategic Policy Institute, the Uyghurs have been moved under a labour scheme known as Xinjiang aid to factories across the country straight from the detention centers. Many of these factories are a part of the supply chain network for well-renowned brands such as Apple, Nike, and Dell.

At the factories the workers are forced to live in separate rooms and are required to take Mandarin lessons under heavy surveillance. They are not allowed to leave their jobs and go back to their families in Xinjiang either.

John Oliver, host of popular US TV show “Last Week Tonight” recently aired an episode wherein he talked about the Uyghurs. “If this is the first time that you’re hearing about an estimated million people who’ve been held in detention camps – mostly Uighurs but also Kazakhs and other ethnic minorities – you are not alone. And it’s probably because China has done its level best to keep this story from getting out,” says Oliver.

John Oliver further said, “While there is clearly nothing new about horrific practices being hidden deep within the supply chain of global capitalism, what is happening to the Uighurs is particularly appalling”.

Despite China’s attempts at keeping the entire crackdown private, more and more horrifying details have come out in the open about the atrocities meted out to the Uyghurs via testimonies from former detainees.

This has led to an increased pressure on China as well as the big brands utilizing the Chinese supply chain network, to cut ties with factories where human rights are being violated under this Uyghur crackdown.

The US has restricted 11 Chinese companies from buying American goods due to claims of them being linked to the Xinjiang region. A coalition of over 180 organizations also called out dozens of clothing brands and retailers for links to the Xinjiang crackdown and forced Uyghur labour.

While some companies like PVH, the owner of brands like Calvin Klein and Tommy Hilfiger are working on reducing their presence in the Xinjiang region’s supply chain network others like Big W, a discount department store chain operated by Australia's Woolworths group acknowledged that some of their products might be unintentionally coming from the regions of Xinjiang province.

Companies like Nike, Puma, and Adidas have however continued to deny allegations of links to factories with forced Uyghur labour completely. In their statement Nike said, "We have confirmed with our contract suppliers that they are not using textiles or spun yarn from the region."

With the increasing spotlight on the Chinese government’s repressive activities,  international pressure is increasing on the business groups which depend on China for supply change, to come clean on any link of their vendors with Uyghur forced labour. There might be some hope, even if very little, for the plight of the Chinese Uyghurs after all.
