Abstract
A floor cleaning machine includes a set of obstacle sensors that detect when the machine is approaching an obstacle. If the obstacle is less than a threshold distance away from the machine, the machine may output an alert and override the operator's command with a command to reduce the speed of the machine. If the obstacle is less than a minimum threshold distance away from the machine, the machine may come to a complete stop to prevent the collision.
