The data are collected on the pole, using an hair drier to increase the temperature of the motor. Please, see https://github.com/ami-iit/element_sensorless-torque-control/issues/204#issuecomment-2757523380 for details.
In the folder raw, you find the original datasets collected on the robot.
In the folder training and testing, instead, you find the parsed datasets in .pickle format, ready to be used for PINN training.
