Gait phase detection plays a significant role in human motion intention recognition in lower limb exoskeleton. This study proposes a LSTM-ResMLP-LightGBM method for real-time gait phase detection in multigrade loads in outdoor activity. LSTM is exploited to extract the underlying meaning and construct a lengthy time relationship in multiple features. https://www.wholisticpet.shop/product-category/canine-travel-gear/
