Resumen

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.
