Myoelectric control systems as the emerging control strategies for upper limb wearable robots have shown their efficacy and applicability to effectively provide motion assistance and/or restore motor functions in people with impairment or disabilities, as well as augment physical performance in able-bodied individuals. In myoelectric control, electromyographic (EMG) signals from muscles are utilized, improving adaptability and human-robot interactions during various motion tasks. Machine learning has been widely applied in myoelectric control systems due to its advantages in detecting and classifying various human motions and motion intentions. This chapter illustrates the challenges and trends in recent machine learning algorithms implemented on myoelectric control systems designed for upper limb wearable robots, and highlights the key focus areas for future research directions. Different modalities of recent machine learning-based myoelectric control systems are described in detail, and their advantages and disadvantages are summarized. Furthermore, key design aspects and the type of experiments conducted to validate the efficacy of the proposed myoelectric controllers are explained. Finally, the challenges and limitations of current myoelectric control systems using machine learning algorithms are analyzed, from which future research directions are suggested.
