  • Motorized robotic walker guided by an image processing system for human walking assistance
    Patent number: 11396314
    Abstract: A motorized robotic walker is capable of moving automatically with the user through an algorithmic process using a 3D camera image processing system. The image processing system can measure relative motion of the user versus the robotic walker and a microprocessor can generate PWM signal to drive motors of the robotic walker so that the robotic walker can follow the user's motion automatically and provide assistance if needed.
