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.

Yemen's Multilayered War: Al Qaeda in Arab Peninsula

The unification of Yemen in 1990 was a direct result of the military defeat of South Yemen at the hand of North Yemen forces. This military defeat and coerced unification implied that Unified Yemen could not achieve real cohesion, preventing the functioning of the nation as a democratic unit.

Meanwhile, newer elements were added to the dangerous mix of sub-nationalism, intra religious division, and tribal loyalty in Yemen. These were the Yemeni veterans of Soviet-Afghan war who fought with the Afghan mujahideen against the Soviet army backing the Afghan government.

These were hardline Wahabi and Salafi fighters, following an idealogy that mandated a strict interpretation of Islam. The fighters returned to Yemen in the early 1990s, after the withdrawal of Soviet forces from Afghanistan. The local Yemeni, both the Zaidi Shias or Maliki Sunni have traditionally followed a more liberal version of Islamic and social practices. Unlike the local Sunnis who were living in peaceful coexistence with the Zaidis Shia, these hardliners were antagonistic to the Shias.

Their arrival was followed by a forceful realignment of the local residents’ religious practices, mandating the local population to strict interpretations and social practices. Osama bin Laden, who had family roots in Yemen, was a conveniently placed ideological mentor. This led to a pushback from both the government forces as well as Shia groups, especially the Houthi-led Ansar Allah movement. In time, these former mujahideen, who were battle hardened and well versed in guerilla warfare, allied themselves with Al-Qaeda to start a low level insurgency in Yemen.

The Gulf war and subsequent stationing of American forces in Saudi Arabia and other gulf countries provided another impetus for the growth of Al Qaeda in Yemen. Consequently, they demanded that coalition forces leave Arabian land, failing which would result in more terror attacks.

Al-Qaeda affiliated groups attacked many installations associated with the US-led coalition forces in Yemen and nearby countries. The most successful of those was the famous bombing of USS Cole in Aden, in 2000. It was followed by a series of attacks leading up to  9/11.

Al-Qaeda in the Arab Peninsula (AQAP) is also known as the Ansar al-Sharia in Yemen is fighting to set up an emirate amidst the lack of leadership post the Houthi rebellion. It was this outfit that claimed responsibility for the attack on the French satirical magazine, Charlie Hebdo, in 2015 and is now considered the most dangerous al-Qaeda outfit by the US.

The CNN reported that “AQAP set out its objectives in a May 2010 statement as the "expulsion of Jews and crusaders" from the Arabian Peninsula, the re-establishment of the Islamic caliphate, the introduction of Sharia, or Islamic law, and the liberation of Muslim lands.”

The full list of attacks and places captured by terrorist insurgents in chronological order can be accessed here.

One of the outcomes of continual terrorist attacks has been a reduction in Hadi’s popularity. He is also seen as weak for not being able to stop al-Qaeda from terrorising Southern Yemen, as well as for not being able to alleviate them from their feeling of marginalization ever since the unification.
