Growing up in poverty in rural Bolivia, Roly Mamani learnt to make his own toys from plastic and cardboard.
Now, those skills are being used to help others as he makes prosthetic limbs.
Through his university years, Mamani cultivated his skills in engineering and electronics.
After his education, he ended up opening a workshop dedicated to robotic toys and educational equipment.
When he happened to hear of an individual without hands, Mamani was determined to construct a pair.
His success led him to combine his skills with 3D printing in the creation of prosthetics for other needy Bolivians.
While above 36,000 people suffer from physical and mobility problems in the country, prosthetics aren't furnished by the state.
The price of a simple 3D printed limb can reach over five times the annual income for someone on the lowest wage.
Roly selects which individuals to assist, together with his physiotherapist brother, Juan Carlos.
Owing to the profits from the robotic toys, they're able to finance a massive proportion without charge, or at a reduced cost.
Pablo Matha's new arm's enabled him to play his instrument.
A prosthetic arm has permitted Marco Antonio Nina to follow his passion.
Hoping to use the recognition his work's received, Mamani intends to establish a rehabilitation centre.
A hero to many, this toymaker believes that science has granted him a superpower.
