En el presente informe, se describe la experiencia del Semillero de investigaci?n GIEM (Grupo de investigaciones electrom?dicas) en el proceso de dise?o e implementaci?n de las partes mec?nica y electr?nica de una pinza rob?tica de bajo costo, accionada mediante la biose?al proveniente de la contracci?n del brazo. Para el control electr?nico, la se?al es captada mediante electrodos semisecos y procesada a trav?s de un amplificador de instrumentaci?n; finalmente la se?al es filtrada, digitalizada, e ingresada a un microcontrolador, que le da a la pinza la orden de abrir o cerrar, a partir de la se?al que detecta mediante sensores el agarre de un objeto. El dise?o mec?nico se desarroll? y verific? funcionalmente en SolidWorks. Posteriormente se realiz? la impresi?n 3D en material ABS (Acrilonitrilo Butadieno Estireno), el cual le redujo peso a la pinza y con ello se garantiz? uno mayor comodidad al infante.This article describes the experience of the GIEM Research Seedbed (Electromedical Research Group) in the process of design and implementation of the mechanical and electronic parts of a low cost robotic clamp, actuated by the biosignal from the contraction of the arm. For electronic control, the signal was captured by semi-dry electrodes and processed through an instrumentation amplifier; finally the signal was filtered and digitized, and entered into the arduino, which gave the order to open or close the clamp from the signal that detected by sensors the grip of an object. The mechanical design was developed and verified functionally in SolidWorks. Subsequently, 3D printing was made on ABS material (Acrylonitrile Butadiene Styrene), which reduced weight to the clamp and with this, greater comfort for the infant.
