VLADIMIR, Bonilla Venegas Félix et al. (Modeling and simulation of the Mitsubishi RV-2JA Robot controlled by electromyographic signals). Enfoque UTE [online]. 2018, vol.9, n.2, pp.208-222. ISSN 1390-6542.

The aim of this work is to control the Mitsubishi RV-2JA Robot using sEMG surface electromyographic signals. The sEMG signals were obtained from the hand through a Myo bracelet with surface sensors. Myo surface sensors are able to detect the electromyographic signals generated by the muscles. The integration of the system was performed in the Matlab Simulink platform to process, identify, validate and control the robot through the electromyographic signals. The hand gestures analysis was performed using a temporal approximation that allowed the extraction of characteristics of the signals. The parameters identified were Electromyographic Integrated (IEMG), Mean of Absolute Value (MAV), Quadratic Mean (RMS) and Variance (VAR), having direct correlation with the type of Hand movement. In order to classify the first movements like spread fingers, wave right, wave left, elder and voor, we used six neural networks, which allow to activate three degrees of freedom of the robot. For the integration and verification of the real-time system, the hardware in loop simulation (HIL) was applied. This simulation allowed the execution of the plant model, the connection with the appropriate control and communication system to verify that the system controls the robot.
