When mobile robot is moved along the isoplanar wall surface of metope, mobile robot can utilize first distance sensor
The positional relationship of 10331 detection data judgement and wall surface.Wherein, the rotation center of mobile robot is in driving wheel rotation axis
On, and first distance sensor 10331 is arranged far from driving wheel rotation axis, so that mobile robot is along wall surface when moving,
Angle between the Forward direction of robot body 101 and wall surface is when predetermined angle (lesser angle) is interior, first distance
The distance value that sensor 10331 detects is proportional to the distance between side and the wall surface of robot body 101 value.Even first away from
The distance value detected from sensor 10331 becomes larger, then the distance between the side of robot body 101 and wall surface value become larger.If
The distance value that first distance sensor 10331 detects becomes smaller, then the distance between the side of robot body 101 and wall surface value become
It is small.

As shown in figure 15, mobile robot is to the distance of wall surface with the preset datum mark in mobile robot to wall surface
Distance H is indicated.The datum mark is located on the straight line where the direction of the launch of 10332 emission detection signal of second distance sensor.
When seeking distance H, the distance value X3 and second distance sensor 10332 detected using first distance sensor 10331 is visited
The distance value X2 measured, wherein distance value X1, the first distance sensor 10331 of datum mark to second distance sensor 10332
The distance between second distance sensor 10332 L is given value.In this way, can be calculated using following formula 1 and formula 2
Distance H.Wherein, L is bigger, and calculated target angle θ is more accurate, and target angle θ is more accurate, then distance H is more accurate.
(X2+X1) cos θ=H formula (2)
It should be understood that there are many types of the mobile robot of the utility model, for example, clean robot, exhibition machine
People or storage robot etc..When mobile robot is clean robot, mobile robot further includes cleaning device, and cleaning device is used
