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: The First Civil War of Yemen

This is the 2nd part of a short explainer article series on the current crisis in Yemen. To read the 1st part of the series click on the link.

After the overthrow of the monarchy in 1968,  Yemen existed as two countries — North Yemen and South Yemen.  These two countries united in 1990, after several years of conflict with one another.

Unified Yemen: Simmering discontent between North & South

A unified government was formed and the work on constitution progressed, however the relations continued to be strained between the two regions. It's important to note that unification was finally achieved after the defeat of the former Marxist state of South Yemen at the hand of North Yemen with active collaboration of Saudi Arabia.

South got a raw deal in the post unification reconstitution and re construction of the country. The government controlled lands, enterprises and other resources in the South were confiscated and given to the ruling elites belonging to the North. However some political representation and economic benefits were given to the southern elites as well.

1st Elections of Unified Yemen: Cracks in unity

The first elections to elect a new parliament of unified Yemen began in 1993. This election was won by the pro-Unification group led by the former President of North Yemen, Abdullah Saleh. The Yemen Socialist Party (YSP) which represented the interests of former South Yemen, was able to win only 54 of the 301 seats.

After losing the democratic election, the leader of YSP, Ali Salim Al-Beidh, withdrew to his base in Aden. He refused to return to the capital unless his grievances of economic marginalization of the south and violence against his party members did not end. This conflict among the ruling elite impacted the general security situation and created an opportunity for the tribal leaders to make a space for themselves as well.

This sense of marginalisation and victimhood of Southern leadership and assertiveness of tribal leadership created a fertile ground for the first civil war of Yemen.

The First Civil War of Unified Yemen

Unlike the political forces, the armed forces of North and South Yemen were not unified at the time of political unification of the country. The political differences between the pro-unification forces and the southern faction led by YSP reached the Northern and Southern armed forces as well. The political infighting soon turned into armed conflict where the armed forces used heavy equipment and air power against each other.

Southern faction leaders withdrew from the reunification and on May 21, 1994, established the Democratic Republic of Yemen (DRY). However they failed to win recognition from the international community. After heavy fighting in the southern part, the government forces captured Aden on July 7, 1994. This led to the collapse of resistance and thousands of political and military leaders left the country. They tried to revive the secessionist movement from Saudi Arabia, but failed to make any impact.

The Ceasefires were called from nearly all sides, including the USA and Russia. The war finally ended in 1994, with Abdullah Saleh being elected as president after an amnesty signing with the Yemen Socialist Party leaders.

However, the YSP was left toothless post-elections, a grievance that would later lead to the forming of the Southern Seperatist Movement (also known as al-Hirak) in 2007.
