A method for automated design of an exoskeleton taking into account the user’s anthropometric data

The method of computer-aided design of the exoskeleton of the lower extremities using parametric design is intended for creating medical exoskeletons of the lower extremities according to the anthropometric parameters of the operator, which allows reducing the error in combining the axes of movement of the exoskeleton joints and the axes of movement of the operator’s joints. The method is based on rebuilding a reference model of the exoskeleton of the lower extremities according to the anthropometric data of the operator and includes the following design procedures: the procedure for taking measurements from the operator, taking the image obtained as a result of 3D scanning, filling out the application form that takes into account operational requirements, outputting the rebuilt exoskeleton model and accompanying documentation. To determine the elemental base of the exoskeleton, a database of electrical and radio components selected for operational requirements is used. To construct a frame corresponding to anthropometric data, a previously created reference model of the lower extremity exoskeleton is used. To test the model, the method also includes a virtual simulation of work by superimposing a rebuilt exoskeleton model on a 3D model of the operator obtained as a result of 3D scanning, followed by checking the animation of movements and the combination of model collisions. To test the effectiveness, we tested the construction of exoskeletons for the anthropometric data of the user using manual and automatic methods.
