Instead of complex systems with less dexterity, we put forth a design considering solely the wrist movement of the prosthetic hand, driven by a flex sensor-Arduino system which translates the motion of natural hand to the prosthetic one. Objective of this paper is to conduct a simulation experiment of this design, using Open Modelica, by creating a virtual lab environment. This paper describes the present state of the research, simulation along with the results obtained and the conclusions we could reach at this period in comparison with the initial hypothesis.

Introduction A person with a limb amputation faces various problems in their daily life and most do not have the fortune of affording the modern prosthetic. Transradial limb amputees constitute around 60% of the total limb amputation [1]. A need for low cost transradial prosthetic was recognized and was worked on. The design thus developed was based on a novel theory in the field of prosthetics, called mirror theory, which allowed the motion of the natural (master) hand to control the prosthetic (slave) hand [2]. Hence, a 3D printed prosthetic limb with an artificial wrist movement, as shown in Fig. 1, which allows grabbing motion at any position of the forearm, was developed. The model is a modification, with official collaboration, of the wrist amputee model from ENable to make it functional for transradial [3]. The actuation of the slave hand is through the movement of the master hand, which is detected with the help of a ex sensor, as shown in Fig. 5, and eventually sent to the motor input of the slave hand via a microprocessor with a simple PID feedback system [4]. Open Modelica, the tool used in this research, is a high level object oriented software for modelling and simulation that stands apart from its parallels with the use of component based modelling as opposed to the block diagram based modelling that allows it to be much simpler to control [5]. Being an acausal method of modelling, Modelica is not governed or operated by the laws of cause and effect [6]. Thus, Open Modelica could be studied extensively by understanding its history, advantages over other comparable tools, and most importantly, with a physical example of a project which would explain the tool in a much wider sense, so that in the future, it could be helpful for students or professionals in their projects and bringing this open source tool to the mainstream.
