The specific embodiment

In order to describe structure of the present utility model and characteristics place in detail, lift explanation of following preferred embodiment and conjunction with figs. as back now:

Please refer to Fig. 1 to Fig. 3, the utility model one preferred embodiment is provided have a detecting obstacle function walk dust catcher 10 certainly, mainly include a body 20, one first road wheel 30, one second road wheel 40 and two sensors 50.

This body 20 generally is oblate column, has the function of moving on a surface, for example at ground motion.This body 20 is by a plastic casing and be arranged at its inner power set and control circuit is constituted, because aforementioned power set belong to prior art and non-this case emphasis with control circuit, so holds the applicant and does not give unnecessary details at this.

This first road wheel 30 and second road wheel 40 are arranged at this body 20 accordingly, and the wheel axle extension line (L) of this first and

second road wheel

30,40 is divided into a first half 21 and one latter half of 23 with this body 20.The first half 21 of this body 20 is provided with a directive wheel 211, can rotate by 360 degree, in order to control the direct of travel of this body 20.In addition, an edge of this body first half 21 equidistantly is laid with three obstacle detection sensors 213 in order to detecting the place ahead obstacle, because this directive wheel 211 and this obstacle detection sensor 213 also belong to known technology, does not therefore give unnecessary details.

Of the present utility model focusing on: this two obstacles detection sensor 50, identical with the action principle of aforementioned obstacles detection sensor 213 in the present embodiment, also for seeing through optical transmitting set, have or not with optical receiver again to receive reverberation and judge whether running-surface is smooth towards the running-surface irradiates light.About the detailed action principle of obstacle detection sensor 50, please refer to applicant application the novel patent of TaiWan, China application M294508 number.One of them of this two obstacles detection sensor 50, as shown in Figure 2, be arranged at an edge of this body latter half of 23, to position that should second road wheel, 40 oblique rears, and contiguous this second road wheel 40, another of this two obstacles detection sensor 50 then is arranged at the edge of this body latter half of 23, to position that should first road wheel, 30 oblique rears, and contiguous this first road wheel 30.Whereby, when when walking dust catcher 10 and retreat, can see through obstacle detection sensor 50 its rears of detecting that are arranged at this body latter half of 23 and whether have obstacle for avoiding the place ahead obstacle.
