How Two Kenyan School Dropouts Made Prosthetic Arms For People With Disabilities

Two young Kenyan inventors have invented bio-robotic prosthetic arms from waste materials to help improve the lives of the physically challenged people in 2021.

Both David Gathu and Moses Kiuna were at the age of 29 when they designed a bio-robotic prosthetic arm in helping the people that have lost their limbs.

Recounting their ordeal before venturing into the invention, the duo said they were forced to drop out of college because of the expensive school fees but did not let the challenges steal their vision.

Gathu and Kiuna accomplished their dream to help their communities in a workshop in Kiambu county in Kikuyu, Kenya, north of the capital Nairobi.

According to Face to Face Africa, the workshop was basically a shed made out of worn-out rusted iron sheets standing next to a chicken coop.

The floor was covered with gravel, making the ground outside the shop and the interior all but indistinguishable, as brown broken glass with tape all around fits the window frame.

Brain signal bio-robotic arm
Another significant thing about the invention was being the world’s first bio-robotic arm operated by brain signals. The invention, which is controlled by brain signals, has been billed as a game-changer in the lives of disabled people in Kenya.

Gathu and Kinyua’s invention was unique and different from most prosthetic technology which is powered by a person’s muscles.

The arm works by converting brain signals into an electric current by a “NeuroNode” biopotential headset receiver. NeuroNode biopotential was originally invented to help people suffering from paralysis and speech loss.

Also, the inventors narrated that the idea to develop an electronic prosthetic came to them during the pandemic as part of their contribution towards assisting Kenya to battle the pandemic. It was initially created to help COVID-19 sanitisation efforts.

“When the virus hit our country, we decided to create a machine that could help us decontaminate surfaces. It can also be used in schools, restaurants, hospitals,” Shoppe Black quotes Kinyua as saying.

Using waste products

According to a report by Anadolu Agency, the Kenyan inventors solved two problems with their innovations, first, by using waste products to make the environment clean and safe, and helping a community of people living with disabilities.

“People throw away a lot of things that are harmful to the environment just because they don’t work. If they don’t work, it might be just one component that’s faulty but all the other components still work and can be recycled,” Gathu said.

“We’ve recycled everything that you see here. They throw it away, we pick it up and use it. This has saved us from spending a lot of money because we’re not backed up financially by anyone to come up with our innovations.”

They picked up “junk” that people threw away – things like plastic, rubber, wiring, old computer motherboards, LED lights, USB devices, switches, optical drives, heat sinks, fans, and power supply units – components that they say could be quite expensive to purchase from a shop.

Helping the community

Speaking about the physically challenged people, he said, “The main reason we came up with this is to help people in our community who have lost their limbs. We don’t want these people to feel like they can’t do anything, we want them to be dependent on themselves.”

The arm can do many more tasks. They say they are still perfecting their device, but lack of funds has been a challenge.

David Mathenge from the Association for the Physically Disabled of Kenya (APDK), a charity NGO, says: “Such inventions are the future of the science of artificial limbs. This is the science we need to ease the challenges people with disabilities face.”

US Suspends Work Visas For Nigerian, Foreign Truck Drivers

The United States government has suspended the issuance of work visas for Nigerian and other foreign truck drivers, citing job security concerns and safety risks for American citizens.

Secretary of State Marco Rubio announced the decision on Thursday, saying it takes immediate effect.

According to him, the rising number of foreign truck drivers on U.S. highways is both threatening lives and reducing opportunities for American truckers.

“Effective immediately, we are pausing all issuance of worker visas for commercial truck drivers.

“The increasing number of foreign drivers operating large tractor-trailer trucks on U.S. roads is endangering American lives and undercutting the livelihoods of American truckers,” Rubio said.

The move comes under President Donald Trump’s renewed clampdown on immigration since returning to office in January 2025.

As part of new measures, travellers from countries with high visa overstay rates or weak travel databases will be required to pay a bond of $5,000 to $15,000 before obtaining certain categories of visas.

The U.S. Embassy in Nigeria also directed all visa applicants to disclose their social media handles from the past five years, warning that failure to comply could result in denial of applications and possible ineligibility for future visas.

Judge Orders Closure Of Trump’s Controversial ‘Alligator Alcatraz’ Migrant Camp

A US federal judge on Thursday barred the Trump administration and Florida state government from bringing any new migrants to the detention centre known as “Alligator Alcatraz” and ordered much of the site to be dismantled, effectively shuttering the facility.

Florida’s government swiftly announced it would appeal the decision.

The detention centre was hastily assembled in just eight days in June with bunk beds, wire cages and large white tents at an abandoned airfield in Florida’s Everglades wetlands, home to a large population of alligators.

President Donald Trump, who has vowed to deport millions of undocumented migrants, visited the centre last month, boasting about the harsh conditions and joking that the reptilian predators will serve as guards.

Japan City Mulls Two-hour Daily Smartphone Limit

A Japanese city will urge all smartphone users to limit screen time to two hours a day outside work or school under a proposed ordinance that includes no penalties.

The limit, which will be recommended for all residents in central Japan’s Toyoake City, will not be binding, and there will be no penalties incurred for higher usage, according to the draft ordinance.

The proposal aims “to prevent excessive use of devices causing physical and mental health issues… including sleep problems,” Mayor Masafumi Koki said in a statement on Friday.

The draft urges elementary school students to avoid smartphones after 9:00 pm, and junior high students and older are advised not to use them after 10:00 pm.

The move prompted an online backlash, with many calling the plan unrealistic.

“I understand their intention, but the two-hour limit is impossible,” one user wrote on social media platform X.

“In two hours, I cannot even read a book or watch a movie (on my smartphone),” wrote another.

Others said smartphone use should be a decision for families to make for themselves.

The angry response prompted the mayor to clarify that the two-hour limit was not mandatory, emphasising that the guidelines “acknowledge smartphones are useful and indispensable in daily life”.

The ordinance will be considered next week, and if passed, it will come into effect in October.

In 2020, the western Kagawa region issued a first-of-its-kind ordinance calling for children to be limited to an hour a day of gaming during the week, and 90 minutes during school holidays.

It also suggested children aged 12 to 15 should not be allowed to use smartphones later than 9:00 pm, with the limit rising to 10:00 pm for children between 15 and 18.

Japanese youth spend slightly over five hours on average a day online on weekdays, according to a survey published in March by the Children and Families Agency.
