Testing Strength Based on the Principle of Robotic Arm Wrestling

This article describes the design and development of an arm that measures human physical condition controlled by a Programmable Logic Controller (PLC), ensuring system control, adjustment, and display of necessary results. A user-friendly interface, both local and remote, will be designed and implemented. The system incorporates safety features to ensure the safety of individuals. The design and implementation are based on a digital twin linked to the control system, including simulation. This approach accelerates the development of application implementation with the possibility of creating control programs for the PLC and fine-tuning the system during the design phase. Safety functions ensuring the safety of tested individuals are applied. The developed system will be portable and will serve for scientific experiments, presentation activities, and as an educational tool.
