Mohammad Javad Azadi on Instagram: "The Simulation of 3-Dof Motion Trajectory. Some robot makers design the robot in mechanical simulation softwares such as Modelica, Dymola, Simulink, and Simscape Multibody. They consider a mathematical model according to the behavior of the robot based on the motor speed. The calculations for finding the mathematical model of balancing robots are gnerally based on either of the two methods: the Lagrange energy method or the analysis of Newtonian forces. In the
