The disclosure includes a system and method for using a robot to prevent risk to a user by identifying a point of interest, determining whether the point of interest is a risk for the user with visual impairments based on the user's position, responsive to a first predetermined threshold for distance being met, determining where to move the robot to mitigate the risk to the user, and instructing the robot to move to a new location. The robot may move between the user and the point of interest to prevent the user from colliding with the point of interest. The robot may use an auditory or tactile warning to warn the user. The tactile warning may be transmitted to a walking stick or a belt worn by the user.
