本申请基于申请号为201610781395.2、申请日为2016年8月30日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及智能家居领域,特别涉及一种机器人及机器人控制方法。
背景技术
清洁机器人是在无使用者操作的情况下,在某一区域自动行进的同时,进行清洁操作的机器人。清洁机器人所在的区域中可能存在用户不希望清洁机器人进入的部分区域,比如地面有水的卫生间,清洁机器人进入后可能会进水从而导致故障,再比如,儿童玩具的聚集地,清洁机器人进入后可能会误将玩具的零碎部件卷入尘盒;由于这些区域的边界通常不存在房门和墙壁等障碍物进行阻隔,因此,为了阻止清洁机器人进入这些区域,用户可以在这些区域的边界处设置虚拟墙,比如,在卫生间的入口处设置虚拟墙。
虚拟墙可以通过设置在地面上的虚拟墙磁条来实现,则清洁机器人在行进过程中,会通过检测组件检测周围的磁场强度,当检测到的磁场强度大于预设的磁性阈值时,确定已经行进至虚拟墙,清洁机器人可以转弯并进入沿边清扫模式。当磁性阈值设置的较大时,清洁机器人需要行进至距离虚拟墙很近时才会进入沿边清扫模式,由于检测组件通常设置在清洁机器人的较中心位置,因此当清洁机器人进入沿边清扫模式时,驱动轮实际已经跨过了虚拟墙磁条进入了用户不希望其进入的区域,仍然会导致上述进水和将玩具的零碎部件卷入尘盒等问题;当磁性阈值设置的较小时,虽然可以避免驱动轮进入这些区域,但是清洁机器人可能在距离虚拟墙较远处已经进行沿边清扫模式,或者,清洁机器人会误将不锈钢家具等存在微弱磁性的物品也误判为虚拟墙而进入沿边清扫模式,导致常常需要用户介入,难以全自动完成复杂环境的清扫。
在实际实现时,为了避免清洁机器人的驱动轮进入用户不希望其进入的区域,也可以在清洁机器人的周边设置两个或两个以上检测组件,由多个检测组件共同识别虚拟墙,但是在清洁机器人中配置多个检测组件会增加电路的复杂度,并且会增加清洁机器人的制造成本,这也是不够合理的。

请参考图4,其示出了一示例性实施例示出的机器人控制方法的流程图。本实施例以该方法用于上述图1A和图1B所示的机器人中来进行说明,该机器人控制方法包括如下步骤:
在步骤401中,通过检测组件检测虚拟墙信号。
可选的,机器人每隔预定时间间隔通过检测组件检测虚拟墙信号,预定时间间隔的长度是系统预设值或用户自定义值,本实施例对此不作限定。
检测组件通常是与设置的虚拟墙的类型对应的,虚拟墙信号是机器人通过检测组件感应到的与虚拟墙的类型对应的信号;可选的,当设置的虚拟墙是磁性条形成的磁性虚拟墙时,检测组件是磁力计时,虚拟墙信号是磁力计感应到的磁场强度;当设置的虚拟墙是磁性条形成的磁性虚拟墙时,检测组件还可以是霍尔传感器时,虚拟墙信号是霍尔传感器在磁场中产生的电位差;当设置的虚拟墙是红外线形成的红外线虚拟墙时,检测组件是红外传感器时,虚拟墙信号是红外传感器检测到的红外线信号。本实施例以虚拟墙信号是磁场强度为例进行说明。
在步骤402中,在机器人的行进过程中,检测虚拟墙信号是否达到第一信号阈值。
第一信号阈值通常是一个较大的经验值。可选的,当虚拟墙信号是磁场强度时,第一信号阈值是2000高斯。在实际实现时,机器人通常要行进至使检测组件与磁性条之间的距离足够小时,检测到的磁性条发出的虚拟墙信号才会达到第一信号阈值,比如,行进至检测组件恰好位于磁性条正上方时。
当虚拟墙所在的环境不同时,由于环境中其他物体的影响,虚拟墙产生的虚拟墙信号通常是不同的,比如,以虚拟墙信号是磁场强度为例,由于机器人感应到的地球磁场强度大小不同,当机器人处于不同高度的楼层时,即使虚拟墙是由相同的磁条形成,机器人检测到的虚拟墙信号也是不同的;再比如,由于电线也会产生磁场,当设置有磁条的地板下方铺设有电线时,机器人检测到的虚拟墙信号与磁条的地板下方未 铺设电线时检测到的虚拟墙信号也是不同的。另外,当虚拟墙的自身性能发生变化时,虚拟墙产生的虚拟墙信号也可以是不同的,比如,当磁条使用较长时间后,磁条的磁性会有所减弱,机器人检测到的虚拟墙信号会逐渐变弱。因此,机器人可以根据实际测量得到的虚拟墙信号对第一信号阈值进行调整,包括如下两个步骤:
1、在机器人的行进过程中,确定虚拟墙信号的最大值。
2、根据虚拟墙信号的最大值对第一信号阈值进行调整。
机器人在对第一信号阈值进行调整时,将第一信号阈值调整至稍小于虚拟墙信号的最大值,其中,稍小于是指虚拟墙信号的最大值与第一信号阈值的差值小于预定阈值,预定阈值是系统预设值或用户自定义值。比如,机器人初始的第一信号阈值为2000高斯,机器人在行进过程中,确定得到的虚拟墙信号的最大值为1900高斯,则机器人将第一信号阈值调整为1800高斯。
在步骤403中,当检测到虚拟墙信号达到第一信号阈值时,确定识别到虚拟墙。
机器人检测到的虚拟墙信号除了包括虚拟墙产生的信号,还可能包括机器人所在的环境中的其他物体产生的与虚拟墙的类型对应的信号,通常情况下,虚拟墙产生的信号通常较强,而其他物体产生的信号通常较弱;比如,虚拟墙是磁性虚拟墙时,机器人检测到的虚拟墙信号是磁场强度,且检测到的磁场强度通常比较强,同时,机器人所在的环境中的不锈钢家具也有磁性,机器人也会检测到不锈钢家具的磁场强度,但是检测到的磁场强度通常较小。
另外,由于虚拟墙产生的信号通常比较强,因此机器人在距离虚拟墙较远时,已经能检测到虚拟墙所产生的虚拟墙信号,若此时机器人就确定识别到虚拟墙从而调整行进方向,显然不够合理。
因此,为了防止将其他物体误判为虚拟墙或过早的识别到虚拟墙,将达到第一信号阈值的虚拟墙信号确定是虚拟墙产生的信号,确定识别到虚拟墙,并执行下列步骤405。
在步骤404中,当检测到虚拟墙信号未达到第一信号阈值时,确定未识别到虚拟墙。
当检测到虚拟墙信号未达到第一信号阈值时,机器人按照当前行进方向继续前进。
在步骤405中,在识别到虚拟墙时,调整信号阈值,控制机器人后退预定距离并沿虚拟墙的外侧行进。
机器人在识别到虚拟墙时,将信号阈值从第一信号阈值切换至第二信号阈值,第二信号阈值通常是一个较小的经验值。可选的,当虚拟墙信号是磁场强度时,第二信号阈值是800高斯。在实际实现时,机器人在距离虚拟墙一定距离的位置检测到的虚 拟墙信号强度就能达到800高斯,比如距离虚拟墙10cm的位置。
机器人在行进时,处于虚拟墙的外侧,虚拟墙的外侧是虚拟墙中处于机器人的活动区域中的一侧,虚拟墙的内侧是虚拟墙中处于机器人的非活动区域中的一侧,非活动区域是机器人没有进入权限的区域。当机器人是清洁机器人时,虚拟墙的外侧是虚拟墙中处于待清洁区域的一侧,虚拟墙内侧是虚拟墙中处于非清洁区域的一侧。
通常情况下,机器人行进至检测组件位于磁性条正上方时,检测到的虚拟墙信号大于第一信号阈值,由于机器人的导向轮在检测组件前方,因此当机器人识别到虚拟墙时,机器人的导向轮通常已经行进至虚拟墙的内侧,如图5A所示的机器人的俯视示意图中,当机器人的检测组件130位于磁性条50正上方时,导向轮123已跨入磁性条形成的虚拟墙内部区域,此时若机器人直接旋转,则机器人的驱动轮会旋转至虚拟墙内部区域。因此,机器人在识别到虚拟墙时,后退预定距离,预定距离是系统预设的经验值,在实际实现时,机器人在后退预定距离时,机器人的导向轮退回至虚拟墙外侧。在上述图5A所示的示例性例子中,机器人在后退预定距离时,俯视示意图变为如图5B所示。
机器人在后退预定距离后,向预定方向旋转预定角度后沿虚拟墙外侧行进,预定方向和预定角度都是系统预设值,本实施例以机器人向左旋转预定角度后沿虚拟墙外侧行进为例进行说明。
可选的,当机器人是清洁机器人时,清洁机器人后退预定距离并沿虚拟墙的外侧行进清洁。
可选的,机器人向预定方向旋转预定角度后,对信号阈值进行调整;或者,机器人对信号阈值进行调整后,向预定方向旋转预定角度。
需要说明的是,虚拟墙可以是任意形状的,图5A和图5B中的虚拟墙形状仅是示例性的,本实施例对此不作限定。
在步骤406中,在机器人沿虚拟墙的外侧行进时,根据虚拟墙信号和第二信号阈值之间的关系调整机器人的行进路线。
该步骤包括两种不同的实现方式:
在第一种可能的实现方式中,该步骤可以实现成为如下几个步骤,如图6所示:
在步骤601中,检测虚拟墙信号是否达到第二信号阈值。
在步骤602中,当检测到虚拟墙信号达到第二信号阈值时,控制机器人向远离虚拟墙的方向行进。
机器人在检测到虚拟墙信号达到第二信号阈值时,向远离虚拟墙的方向旋转预定角度并行进,预定角度是系统预设值或者由清洁机器人根据虚拟墙信号与第二信号阈 值之间的差值确定,本实施例对此不作限定。
通常情况下,当步骤405中,机器人向左旋转并沿障碍物行进时,远离虚拟墙的方向是向左;当机器人向左旋转并沿障碍物行进时,远离虚拟墙的方向是向右。
在步骤603中,当检测到虚拟墙信号小于第二信号阈值时,控制机器人向靠近虚拟墙的方向行进。
本步骤的实现方式可以结合上述步骤,本实施例对此不再赘述。
在一个示例性的例子中,机器人以沿着虚拟墙进行清扫的示意图如图5C所示,机器人10中的三角形的朝向表示机器人10的行进方向,机器人10在沿虚拟墙的外侧行进清洁时,根据虚拟墙信号和第二信号阈值不断调整行进方向,大致以波浪线方式行进,图5C中的虚线表示机器人10的行进方向。需要说明的是,图5C中虽然示出了机器人10的波浪线行进方向,但在实际实现时,机器人10调整行进方向的频率通常较高,机器人10在用户看来仍然是沿着虚拟墙直线行进的。
在第二种可能的实现方式中,该步骤可以实现成为如下几个步骤,如图7所示:
在步骤701中,根据采集到的预定个数的虚拟墙信号拟合出行进路线。
其中,行进路线与虚拟墙的外侧形成的形状相对应。通常情况下,虚拟墙的外侧形成的形状是规则形状,比如,当虚拟墙为磁条形成的磁性虚拟墙时,虚拟墙通常是直线或者圆弧,为了使机器人以更加平滑的行进轨迹沿虚拟墙的外侧行进,可以根据采集到的若干个虚拟墙信号拟合出行进路线。预定个数是系统预设值或用户自定义值。
比如,以虚拟墙信号是磁场强度为例,预定个数为10个,当机器人采集到的10个磁场强度均为800高斯时,机器人拟合出的行进路线是沿机器人的当前行进方向的直线。
在步骤702中,当检测到虚拟墙信号与第二信号阈值的差值在预定范围内时,控制机器人沿行进路线行进,并根据虚拟墙信号对行进路线进行调整。
其中,预定范围是系统预设值。当虚拟墙信号与第二信号阈值的差值超过预定范围时,机器人可以通过上述步骤601-603所示的方法调整机器人的行进路线,本实施例对此不再赘述。
可选的,机器人沿虚拟墙形成的区域行进一周,或者,如上述图5A-5C所示,机器人沿虚拟墙行进至机器人感应到实体墙等障碍物时,机器人确定沿虚拟墙的外侧行进结束,则该方法还包括如下几个步骤,如图8所示:
在步骤801中,检测虚拟墙信号是否小于第二信号阈值。
在步骤802中,当持续检测到虚拟墙信号小于第二信号阈值的时长达到预定时长 时,确定机器人沿虚拟墙的外侧行进结束。
比如,连续3秒检测到的虚拟墙信号均小于第二信号阈值,则确定机器人沿虚拟墙的外侧行进结束。
在步骤803中,在机器人沿虚拟墙的外侧行进结束时,再次执行根据信号阈值和虚拟墙信号识别虚拟墙的步骤。
当清洁机器人沿虚拟墙的外侧行进结束时,为了再次避免误判,重新使用数值较大的第一信号阈值识别虚拟墙。
综上所述,本公开实施例提供的清洁机器人清洁方法,通过设置两个不同的信号阈值,在机器人的行进过程中,根据信号阈值和通过检测组件检测到的虚拟墙信号识别虚拟墙,在识别到虚拟墙时,调整信号阈值,并根据调整后的信号阈值和虚拟墙信号控制机器人沿虚拟墙的外侧行进,在识别虚拟墙以及控制机器人沿虚拟墙外侧行进时,使用不同的信号阈值,解决了只设置一个较大的信号阈值时导致的机器人的驱动轮跨入虚拟墙内部或者只设置一个较小的信号阈值时发生误判导致的需要用户介入,难以全自动完成复杂环境的清扫的问题;达到了在准确识别到虚拟墙的基础上,保持机器人在沿虚拟墙的外侧行进时,机器人的驱动轮位于虚拟墙的外侧,不进入虚拟墙内部区域的效果。
