摘要
从发明人提供的背景资料中，新闻记者引用了以下引文：“自主或半自主的机器人设备越来越多地用于消费家庭和商业机构。这种设备可能包括机器人真空吸尘器、割草机、拖把、一个仍然存在的问题是，机器人设备经常遇到的问题是，由于各种情况，机器人设备变得不可操作，因此需要个人的物理干预来纠正问题。例如，如果机器人清洁器的刷子卡在电线周围，在另一个例子中，机器人清洁器的刷子可能由于与毛发等纠缠而卡住，并且不再能够正常旋转，在其他例子中，机器人设备可能会在未预期的高度变化上卡住，遇到意外的倾斜等，个人必须介入以协助机器人设备。虽然机器人设备不可避免地会在工作环境中完全遇到问题，机器人装置能够独立地克服这些问题是可以预见的，当机器人装置遇到问题时，它可能使机器人装置不能工作，这是不希望的，因为机器人装置可能无法完成所要求的工作，而且这是不可取的，因为它经常需要外部帮助来克服这个问题。需要一种方法来使机器人设备能够独立地克服这些问题。
Abstract
From the background information supplied by the inventors, news correspondents o btained the following quote: “Autonomous or semi-autonomous robotic devices are increasingly used within consumer homes and commercial establishments. Such devi ces may include a robotic vacuum cleaner, lawn mower, mop, or other similar devi ces. One issue that remains is how that robotic devices often encounter is that the robotic devices become inoperable due to a variety of circumstances thereby requiring the physical intervention on the part of an individual to rectify the issue. For example, if a brush of a robotic cleaner becomes stuck around, for ex ample, an electrical cord, the robotic device may become inoperable as the brush will no longer be able to spin, and an individual must come to detangle the ele ctrical cord from the brush. In another example, brushes of robotic cleaners may become stuck due to becoming entangled with hair or the like and no longer be a ble to spin properly, the individual in turn must come over to detangle the hair from the brush. In other examples a robotic device may become stuck on an unexp ected elevation change, encounter an unexpected dip or the like and an individua l must intervene to assist the robotic device. While it is unavoidable that robo tic devices will encounter issues in the work environment completely, it is pref erable that a robotic device be able to overcome such issues independently. When a robotic device encounters an issue, it may render the robotic device inoperab le which is undesirable as the robotic device may not be able to complete work t asks, and it is further undesirable as it often requires outside assistance for overcoming the issue. A method is needed for a robotic device to be able to over come such issues independently.
