arm robotic
The braso robotico is an invention that will allow people without one of their arms to be able to implement this type of device and to achieve motor control and to feel as before.
Although electronics lovers have tried and / or managed to make this kind of inventions, the cost of carrying out this type of projects, whether with research costs, materials, servo, controllers, etc., requires a great economic investment.
Hopefully in the future as technologies advance these elements can be more accessible to all people who need it and thus be able to contribute to society.
