CLEANING MACHINE WITH COLLISION PREVENTION

摘要

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.

主权项

1. A floor cleaning machine, comprising:
a drive wheel; a motor that, in operation, causes the drive wheel to turn; a speed controller that controls the motor; one or more motion sensors that, in operation, detect a speed and a direction of movement of the machine; one or more obstacle sensors that, in operation, detect data representative of an object that is external to the machine; a processor; and a memory containing programming instructions that are configured to instruct the processor to:
receive an operator command to drive the machine;receive the speed and direction of movement of the machine;receive the data representative of the object;use the speed measurement and direction of movement to determine whether the machine is expected to collide with the object; andin response to determining that the motor is expected to collide with the object, generate one or more instructions to override the operator command and reduce the speed of the machine.
