This document represents the final thesis of Mr. Alvaro polo Brihuega, which consists of a study of the servo motors dynamisel and design a solution for controlling them.This solution will use a VHDL programmed FPGA connected to the servo motors and the subsequent study of the changes that occur in the servo to get some resources to control their movement and the torque which plays such movent with respect to external forces. All this will be pointing to an ultimate goal as the control of changes instrength and dampen the same as falls and bumps in systems with installed servo
