In the suburbs of Kikuyu in Kenya\u2019s Kiambu County, 29-year-old Moses Kiuna and his cousin David Gathu are fiddling with wires and electric cables in their workshop, their grandmothers\u2019 former granary.<\/p>\n\n\n\n

They have been doing this since they were children \u2014 dismantling toys, radios and TV sets, despite the spankings their fiddling attracted from their parents. <\/p>\n\n\n\n

Today, their tinkering is a lot more advanced. The cousins are making robots that can assist people with disabilities perform simple tasks without assistance. They already have two prototypes under their belt. <\/p>\n\n\n\n

Their desire to create assistive technology came about in 2009, when they decided to try to help a classmate who had been born without a hand.<\/p>\n\n\n\n

\u201cWe had a friend who was a congenital amputee and had one hand. We would see him struggle to write, eat and do other things that other children did with ease. It\u2019s then that we began asking ourselves how we could help him, and others, move from being dependent to independent persons,\u201d said Kiuna.<\/p>\n\n\n\n

Their early experiences developed into an insatiable appetite for robotics, and they haven\u2019t looked back. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The self-taught innovators began studying the science behind how the brain sends signals to the nervous system for motor activity to occur. Armed with this knowledge, they developed a robotic prosthetic that functions like a human hand, to aid those who have lost arms because of accidents, illnesses or congenital disabilities. <\/p>\n\n\n\n

The assistive device is worn on the head and back of the affected person to enhance communication between the brain and the prosthetic arm. <\/p>\n\n\n\n

\u201cThe gadget uses brain signals received from the headset receiver and converts the user\u2019s intentions into actions performed by the robotic arm. Decisions are transmitted by electric currents from one cell to another and are translated into various movements,\u201d Gathu explained.<\/p>\n\n\n\n

The cousins carefully arranged the components in electronic gadgets so that the output makes a circuit. They then made a wood carving mimicking the human hand, complete with various joints. After many attempts, they devised a prototype that uses electric signals to control the prosthetic arm\u2019s movements. <\/p>\n\n\n\n

The device can facilitate movement along the shoulder, elbow and the wrist. It can also assist in moving the hand up and down, grabbing and releasing, picking up a drink, opening a door, turning the lights on and off, and performing other simple tasks it has been programmed to perform. <\/p>\n\n\n\n

Gathu says the robot\u2019s movements are limited because of the materials it is made of. He is optimistic that they can make a more durable, fashionable and flexible device with the appropriate wares. They say they are still perfecting the device, but a lack of funding has been a problem.<\/p>\n\n\n\n

To accommodate people who have lost their mobility from the neck down or who have developed quadriplegia from accidents or disease, they\u2019ve also invented a robot with a human interface that uses artificial intelligence (AI). <\/p>\n\n\n\n

Nicknamed Jeff, the robot receives commands in English and Swahili and can respond accordingly. Jeff can be placed on a surface or mounted on a wall.<\/p>\n\n\n\n

\u201cWe had our fellow Africans in mind when we programmed Jeff in Swahili in order to serve the people in the region who don\u2019t speak English. We also intend to programme some in our local languages,\u201d Kiuna said. <\/p>\n\n\n\n

Like the prosthetic arm, Jeff is also made of recycled electronic waste materials, leather and wires that the two buy from repair shops or collect from dumpsites.<\/p>\n\n\n\n

And although they are proud of how far they\u2019ve come towards making their dream a reality, some impediments still stand in their way. <\/p>\n\n\n\n

\u201cAccess to cutting-edge equipment and materials that can graft plastics or aluminium and enable us to design a hand that is similar in function to the real hand would make a lot of difference,\u201d Gathu said.<\/p>\n\n\n\n

They also believe they could do more with a regular workshop. Operating out of their grandmother\u2019s granary, their equipment is often damaged.<\/p>\n\n\n\n

The first robot they made, which took them two years to put together, was rained on, and they had to rebuild it from scratch.<\/p>\n\n\n\n

They also say although some organisations have offered to partner with them, the terms of agreement have not been palatable because they require the cousins to give up ownership of their innovation.<\/p>\n\n\n\n

\u201cSome learning institutions have asked us to give up the innovation in exchange for an opportunity to pursue higher education, but we don\u2019t think it\u2019s worth it, considering we\u2019ve taught ourselves what we know about robotic technology so far,\u201d Kiuna said.<\/p>\n\n\n\n

Their dream is to have a research centre that will bring together creative minds from various fields, especially in designing robotic devices that are durable, fashionable and flexible \u2014 and that could be competitive worldwide. <\/p>\n\n\n\n

Their grandmother, Mary Kabura, says she is proud of the young men and has given them a small portion of her land where they can put up a modern workshop should they get resources.<\/p>\n\n\n\n

\u201cI\u2019m impressed by their dedication and desire to meet a need in society. I have given them this small piece of land to set up their workshop, and I hope to see their robots launched in the market one day,\u201d she said.<\/p>\n\n\n\n

Gathu and Kiuna believe their innovations can be game changers for persons living with disabilities and hope that their company, Afro-Genesys, will one day be mentioned alongside giants in the robotics industry.<\/p>\n\n\n\n

Over the past year, several African ventures have stepped into the field of robotics. Uniccon Group, an Abuja-based tech startup, recently unveiled Africa\u2019s first humanoid robot, Omeife. <\/p>\n\n\n\n

The launch of Omeife came a few months after Abdul Malik Tejan-Sie, a South-African-based, Sierra Leonean innovator, presented a prototype of South Africa\u2019s first humanoid robot.<\/p>\n\n\n\n

A 2021 Government AI Readiness Report ranked Mauritius, South Africa, Kenya, Ghana and Cabo Verde as the most accommodating and prepared for AI uptake in the continent, while the United Nations Economic Commission for Africa (ECA) estimates that Africa\u2019s economy could hit US$15.7 trillion by 2030 if the continent adjusts and taps into 10% of the global AI market.<\/p>\n\n\n\n

Early in 2022, the ECA opened the African Research Centre on Artificial Intelligence at the Denis Sassou-N\u2019Guesso University of Kint\u00e9l\u00e9 in the Congo Republic. The AI Centre offers training in the areas of AI and robotics and offers a master\u2019s degree in artificial intelligence and data science to African students. \u2014 Bird Story Agency<\/p>\n","protected":false},"excerpt":{"rendered":"
