DC motor selection for robotic applications

This post was mainly contributed by members of electrical team of ARES. For designing a rover prototype we have to select motors for applications like Robotic arm, wheels etc.  This post aims to be a single guide containing all the information required for someone to select a motor for his application. I’ll try not to cover motor constructional details, but rather their types, advantages and application areas.   Type of DC electric motors used in robotic :…
