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.

How the People Power brought down a Dictator in Sudan

Africa has witnessed many transformative events in the past decade. Among these, a people-led movement in Sudan that has overthrown a dictator in 2019 will undoubtedly take the cake.

The country has been under the ironclad rule of General Omar al-Bashir for over 30 years. The regime which came in power after a military coup in 1989, used strong arm tactics to control a nation of the diverse group of people. Furthermore, the 30 years long repressive military rule had overpowered every institution that promoted the cause of human rights. It also empowered the conservative Islamic leadership that had put harsh restrictions on women.

The regime of Omar al-Bashir was fiercely opposed by the Western countries while Saudi Arabia and the United Arab Emirates were its heavyweight backers. It had to grapple with people led movements throughout its existence which also included a full blown insurgency movement in Darfur region. However it was able to put down any challenge through brutal force.  

The people's movement to overthrow General Omar al-Bashir started in December of 2018 had such inclusiveness which was not witnessed in the earlier movements. It was powered by all the classes and ethnicities in posh as well as the poorest of neighbourhoods. Some adrenaline-fuelled women leaders encouraged other women to participate in the protests which not only increased the diversity of the people fighting for the nation but also helped to keep the movement non-violent. It also had the youth power which was yearning for a better future for them and their country.

The mobilization of millions of citizens on the streets forced the government to block the internet throughout the country for weeks. With online communication difficult to make, the protestors started using old ways to mobilise, such as megaphones, graffiti all over the streets and crowd-pulling events like a community service day. This included clearing trash areas in clothing that promoted their movement saying: ‘We will build what we are dreaming of.’

The protesters demanding civilian rule were met by violence which caused death and injury, many of which were caused by gunshot wounds. However people didn't relent and continued to protest. Huge protests were organised to correspond with the 30th anniversary of the coup that helped bring Bashir to power.  The nation was ready to make people’s revolution happen and was ready to pay the cost.

After the relentless protest, General Omer Al Bashir, who ruled with the backing of the military, was finally overthrown by the military in April 2019. However the people were not ready to accept another military ruler  to replace the earlier one. So the people's movement continued till the military leadership relented to disband the Transitional Military Council and in its place an eleven-member Sovereign Council was constituted in November 2019.

The Sovereign Council, made up of the  six civilians and five military representatives, is mandated to rule Sudan and conduct a free & fair election in the next three years. Amongst the civilian council members nominated by the protest movement, there is a woman and a journalist. This in itself is a great step forward for the long oppressed citizens of Sudan.
