Brazo robot dibujante V2. (Monstruosidad tecnológica) Los resultados del brazo robot dibujante anterior no tuvieron una gran resolución. Mi idea inicial era hacer que pudiera escribir y eso resultaba imposible. Esto se debía principalmente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada tramo […]

Panasonic, together with the Belgium-based research institution IMEC, has developed a DNA testing chip that automates all stages of obtaining genetic information, including preprocessing. This development is expected to enable personalized, tailor-made therapy to become widespread. SNPs are variations in a single DNA base among individuals. Detecting SNPs makes it possible to check whether genetically
