One of the problems with accessibility for people who are deaf is often the lack of budget to hire language interpreters. sign language. This problem can be solved by a A robotic arm Developed by the National University of Columbia, it can translate conversations into sign language.

Andres Felipe Torrijo, Gustavo Montero and Diego Jaramillo. i Edward DiazThe creators of this innovative device noted that “if it bends or makes a flexing motion, it will be the same as a robotic arm.” In short, it is a flexible sensor, which is an elastic band that imitates the movement of the fingers of the hand.

The device was created in a course called Manufacturing Processes so that he could contribute technological With its own design, at a low price and, therefore, more accessible to people with low economic resources.

How is this robotic hand?

The robotic hand prototype consists of a palm, rings and tendons like wires connected to a motor. The staff is ABS (plastic) and controls a device called arduino which is a programmable controller. He made a model of a robotic arm computer and printed 3D.

the aforementioned student TorrijoIt proves that applied robotics is a great advance in medicine, and several medical departments have benefited from the use of more precise robots, which offer even more possibilities for the diagnosis and treatment of various diseases, as well as assistance such as replacement. Patients and functions.

“The goal of the robotic arm is to teach sign language to people who don’t know it and to improve those who already do. Similarly, there is a need for new students to explore new models of robotic arms and improve their technique,” ​​the student added.

“The development of robotics has made it possible to create intelligent prostheses, artificial elements equipped with a certain autonomy, which allows to partially or completely replace the functions of amputated limbs after an accident or any kind of damage,” he noted. in turn.student a hunter.

The design of the prototype took into account what was determined by the Physical Medicine and Rehabilitation Association of Colombia, according to which the prevalence of upper limb amputation in the country is 65 to 100 people per 100,000.

The figure estimates that approx 10% The population has some kind of disability And 5 or 10% of disabled people are amputatedAnd a third of them have upper limbs amputated.

“It was not only aimed at enhancing the students’ ability to generate projects using different branches of mechatronics engineering, but they are given as projects that can be used to solve different situations or problems in the region,” said the professor. Juan Jairo Vaca Gonzalez.

Other projects were implemented in the field MechatronicsThese include a photocatalyst (for improving biomass production processes and processes), production cell simulation (focusing on various product processes), and an automated aquaponic system (for use in fish farming).

“The activity is important because, in addition to making visible the classroom model of the Academic Innovation Lab at our headquarters, it is also a space to promote and strengthen networks with local and national actors, allowing us to publicize what we are working on through mentoring.” teachers,” he concluded IBET CHRISTINA ROMERO CALDERONProfessor and Director of Research and Extension at UNAL in La Paz
