A wearable exoskeleton robot for the waist can provide support and enhance human waist movements through its framework and electric motors. This type of robot is commonly used to assist workers, people with disabilities, or the elderly in performing heavy physical labor or providing support and reducing fatigue during long periods of standing or sitting. The robot can also be used for rehabilitation therapy to help restore patients' walking and balance abilities. It features three modes of assistance: 1. Lifting assistance mode (provides 30kg of assistance to the user), 2. Balance assistance mode (reduces fatigue caused by long-term bending), and 3. Walking assistance mode (uses an intelligent drive system to output natural walking power and improve leg movement).
