The warning horn (16) is fixed on robot body (1) front end, can have the function that whistle warning.
7. a kind of crawler type Intelligent Mobile Robot active obstacle system according to claim 1, it is characterised in that:Also Including illumination system (24);
The illumination system (24) includes lighting lamp device (15) and lighting base (19), and the lighting lamp device (15) passes through Lighting base (19) is fixed on robot body (1) front end, and light filling is provided in low light situations for crusing robot.
8. a kind of control based on claim 1 to 7 any one of them crawler type Intelligent Mobile Robot active obstacle system Method processed, which is characterized in that include the following steps:
Step 1: crusing robot when carrying out inspection work, using the environment around sensory perceptual system (21) detection, passes through detection Determine that the self-position of crusing robot, wherein binocular vision sensor (7) acquire environment with the range informations of surrounding objects The environmental information around identification robot, extraction machine people's road ahead Edge Distance, height are reconstructed based on 3 D stereo after image It spends and the level and area information in region to be driven into;
Step 2: the information that processing crusing robot sensory perceptual system (21) obtains, before judging whether crusing robot can be crossed Square obstacle, if it is possible to it crosses, enters step three, judge whether that front obstacle can be bypassed if it cannot bypass, if Front obstacle can not be bypassed, then industrial personal computer (13) sends out control signal and gives alarm system (27), and staff is reminded to come Processing;
Step 3: detecting barrier and robot body by binocular vision sensor (7) and IR evading obstacle sensors (4) (1) distance, control robot are run to immediately ahead of barrier in safe range;
Step 4: control obstacle detouring branch arm unit (14) rotates up, preset height is progressivelyed reach, main crawler travel unit is controlled (9) it works, in the process, the angle of obstacle detouring branch arm unit (14) rotation gradually increases and the position of setting and angular relationship Match, the level inclination of robot and lateral inclination angle obtained by obliquity sensor (10), control robot both sides Athey wheel to Preceding movement velocity, while controlling robot and lateral tilt does not occur;
Step 5: control obstacle detouring branch arm unit (14) and bar contact, main crawler travel unit (9) and obstacle detouring branch arm unit (14) driving force of advance all is increased with bar contact, the final function of realizing throwing over barrier.
9. crawler type Intelligent Mobile Robot active obstacle control method according to claim 8, it is characterized in that:It is described In step 2, the mode of robot throwing over barrier is according to the geomery using binocular vision sensor (7) detection barrier Radius with robot ambulation wheel radius, a height of H of obstacle, the traveling wheel of robot is R, height and the robot row of barrier The related coefficient for walking wheel is K=H/R;
The size that the related coefficient of the height for carrying out disturbance in judgement object and robot ambulation wheel is K=H/R, as K < 1, machine People can direct throwing over barrier then need the auxiliary of swing arm crawler belt and traveling crawler collective effect that can just turn over as 1≤K More.
10. crawler type Intelligent Mobile Robot active obstacle control method according to claim 8, it is characterized in that: In step 4, control obstacle detouring branch arm unit (14) is rotated upwardly to preset height, this preset height is by barrier and robot And distance decision;
Robot is set as O points, and the upper end of barrier is arranged A points, is installed with robot water prosposition and be set to B points, if being regarded in robot AngleRobot downwards angle of visibilitySubtense angle ∠ AOB=μ between downwards angle of visibility and upward angle of visibility, barrier incline Oblique angle is ∠ ABC=ψ, and the distance of Robot Binocular Vision sensor to ground is h0, barrier highest point is to ground distance H, then in △ Α BC, ∠ ACB=90 °, the relationship between robot obstacle detouring support arm swing angle and barrier gradient is:So obstacle detouring support arm swing angle is:
