The advancement of electronics enables the development of more complex functional prosthetics with more capabilities and functionality. The prosthetics currently developed do not leave the laboratory environment due to their complexity or the requirement to operate in conjunction with laboratory computing equipment. Therefore, it is essential to develop prosthetics that can operate outside of the laboratory environment while maintaining maximum functionality. Consequently, an electronic control system is developed that can be embedded in a functional prosthetic hand, which is then trained in real-time through electromyography (EMG) using a classification algorithm based on machine learning. The system allows the prosthetic hand to assume six different positions and be controlled by electromyography, recognizing flexion and extension movements of the wrist. This results in a control system that can be fully embedded in the prosthetic hand, with an appropriate weight and size to maintain the aesthetics and functionality of the prosthesis.

Autonomous functions for navigation and localization have piqued the attention and interest in many fields of science and engineering as automotive, aviation and robotics. Desiring high quantity of autonomous products, the used components are requested to be cheap. This often lead engineers or developers to apply micro-electromechanical systems that exhibit large errors. To use these sensors anyway, the acquired data must be processed online for error reduction. Hence there is a need for an algorithm that is easy to compute. The aim of this research is to develop a generic algorithm based on a Gauss-Markov process representing the drifting bias that can be parametrized easily and performs well on real-time systems. Therefore, the error model imitates the sensor's output and removing the errors afterwards. Finally, a validation of the suggested algorithm is performed by comparing processed data of the micro-controller to data processed a posteriori on a high-performance computer.

This paper evaluates three control systems for the propulsion of remote-controlled unmanned underwater vehicles utilizing direct current (DC) motors with propellers. Simulation models based on dynamic and static propeller parameters were used to compare closed-loop control systems with Proportional-Integral-Derivative (PID) and multi-loop controllers, alongside an open-loop control system based on static propeller characteristics. The results reveal that the multi-loop control system exhibits superior performance by effectively controlling transient processes and mitigating external disturbances on the motor shaft. In contrast, the traditional PID controller achieves near-zero velocity error but experiences longer response times and armature current oscillations during startup. The open-loop control system offers comparable performance to the multi-loop system with simpler implementation and similar startup current levels to the PID controller. The study concludes that the choice of control strategy should be based on operational conditions: an open-loop system is advisable for environments without significant propeller obstructions due to its simplicity, while the multi-loop control system with current saturation is recommended in settings with potential disturbances to minimize current levels and reduce failure risks.
