When the existing four-wheeled walking mechanism walks on an uneven ground, there will be a case where the driving wheel is suspended or the four wheels are grounded but the force is not uniform, that is, the ground pressure is not equal. In this case, The friction between the wheels and the ground is different, and it is prone to slipping, which affects the walking trajectory.

Through the above technical solution, the traveling mechanism provided by the present disclosure can drive the driving wheel 21 to rotate about its pivot axis and move up and down relative to the base 11 by setting the elastic biasing member, and adjust the ground pressure of the driving wheel 21 in real time to ensure two The friction between the driving wheel 21 and the ground avoids slipping or ensures that the degree of slip between the two driving wheels 21 and the ground is substantially the same, ensuring the actual amount of movement, thereby ensuring the walking trajectory.

As shown in Figure 11. The second end of the resilient biasing member biases the mounting bracket 211. Alternatively, the resilient biasing member may be configured as a spring plunger 22 that is fixed to the base 11 and the head of the spring plunger 22 abuts against the mounting bracket 211 Used as the second end. Furthermore, in order to provide sufficient elastic biasing force, each of the driving wheels 21 may be provided with two spring plungers 22 correspondingly.

Optionally, the central rotation axes of the two driving wheels 21 are collinear, the driven wheel set includes two pairs of the driven wheels, wherein a pair of the driven wheels are located in the direction of the central axis of rotation One side of the driving wheel 21, and the other pair of the driven wheel are located on the other side of the driving wheel 21, by which the traveling mechanism is allowed to turn 360° when moving forward or backward. Alternatively, the two pairs of the driven wheels are symmetrically arranged about the central axis of rotation such that the center of gravity of the running mechanism falls on the center of the line of the central axes of rotation of the two drive wheels 21.

Wherein, in the running mechanism provided by the second aspect of the present disclosure, the above-mentioned universal wheel may be configured in any suitable manner.

(Of course, it is also possible to provide an internal thread on the hollow output shaft), which is fixedly connected to the telescopic arm 31. Thus, when the hollow output shaft rotates, for example, in the forward direction, the telescopic arm is moved toward the first direction, and when the hollow output shaft is, for example, reversed, the telescopic arm is moved toward the second direction opposite to the first direction, thereby adjusting the clip. Hold the position of the device in the lateral direction.

In order to prevent the weight of the hollow shaft motor, the telescopic arm 31, the rotating arm 32, the clamping device and even the target object 400 from being borne by the screw rod 341, the screw rod 341 is deformed or even broken and the normal operation is affected. The hollow shaft motor can be fixed to the first fixing plate 351, the telescopic arm 31 can be fixed to the second fixing plate 352, and the first fixing plate 351 and the second fixing plate 352 are both fixed to the slider 361, the slider 361 cooperates with a guide rod 362 extending in the lateral direction provided on the apparatus provided with the mechanical arm 3, so that the telescopic arm 31, the rotating arm 32, the clamping device and even the target object 400 can be driven with the hollow shaft motor The rotation moves in the lateral direction. In this case, the weights of the hollow shaft motor and the telescopic arm 31, the rotating arm 32, the clamping device and even the target object 400 pass through the first fixing plate 351 and the second fixing plate 352 and the cooperation of the slider 361 and the guide bar 362. Passed to the device, which is assumed by the device. In the embodiment shown in Figures 17 and 18, the guide bar 362 is disposed on the riser 12 of the autonomously moving handling robot. Alternatively, the telescopic arm 31 extends in the lateral direction and is hollow to facilitate wiring.

In the following, the unmanned workshop of the semiconductor factory will be used as a working environment to transport the foup box as the target object 400 between the shelf and the machine as a work content, and the working process of the autonomous mobile handling robot will be described in detail with reference to the accompanying drawings.

First, after the idle autonomous moving handling robot receives the command, the driving traveling mechanism is driven to the front of the shelf. At this time, the autonomous moving handling robot positions the shelf station, and the distance between the shelf and the shelf is detected by the distance detecting device 113 on the left and right sides. The two distances are compared. If they are equal, the autonomous mobile handling robot is facing the shelf. Otherwise, the control system controls the rotation of one or two of the driving wheels 21 to adjust the autonomous moving handling robot to align with the shelf. Thereafter, the second driving device 332 is operated to send the jig 4 to the front of the foup box to be gripped on the shelf. At this time, the camera camera 491 on the jig 4 takes a picture to the front, grabs the visual feature point, and the control system determines this. Whether the position of the clamp 4 is in the aligned position, and if so, the second drive 332 of the two robots synchronously drives the rotary arm 32 to rotate about its hinge axis to synchronously move the two clamps 4 forward to The positions to be gripped are respectively located on both sides of the foup box. If not, the two telescopic arms 31 can be moved to the left or right by controlling the rotation of the first driving device 331 so that the jig 4 reaches the aligned position. Thereafter, the first driving device 331 controlling the two robots drives the two telescopic arms 31 to move relative to each other such that the two clamps 4 are close to each other, so that the clamped portion of the foup box enters the clamping space of the clamp 4, respectively An elastic grip 421 is held on the support table 411. When the clamp 4 is in contact with the foup box, if the end of the positioning member 44 is aligned with the mark on the foup box, a confirmation signal is sent to the control system, the control clamp 4 continues to move relatively, and the second elastic clamp of the two clamps 4 The member 422 is elastically deformed to provide a relative clamping force from both sides of the foup box, and the positioning member 44 is retracted by the thrust of the foup box. When approaching the proximity sensor 45, the proximity sensor 45 sends an acknowledgment signal to the control system. The control system controls the robot arm 3 to stop moving, the clamp 4 stops, and the first signal light source 47 thereon emits green light, indicating completion of the clamping of the foup box. If the end of the positioning member 44 is not aligned with the mark on the foup box, an alarm signal is sent to the control system, the control system stops the movement of the robot arm 3, and controls the first signal source 47 to emit red light and/or sound signals. To inform the user, adjust the position of the foup box so that the clamp 4 can be properly clamped.

After the clamp 4 is clamped to the foup box, the control system controls the movement of the robot arm 3 to place the clamped foup box on one of the carriers 5, for example, the lowermost carrier 5. When the Foup box is placed on the carrier 5, if the positioning hole of the foup box cooperates with the positioning structure 52, the target object detecting means 54 sends an acknowledgment signal to the control system indicating that the foup box has been placed on the carrier 5. Through the RFID antenna 53 on the carrier 5, the FID code of the foup box can be read, thereby obtaining information of the foup box placed on the carrier 5.

Since then, the loading of a foup box has been completed.

By analogy, after the loading of the last foup box is completed, the control system controls the running mechanism so that the autonomous moving handling robot moves to the next foup box on the shelf to be loaded, and the loading of the foup box is performed. .

After full load, the control system controls the autonomous mobile handling robot to walk to the machine to unload the vehicle. During the walking process, the bottom plate image is taken by the bottom camera 116 to obtain the characteristics of the bottom plate to determine the current position of the autonomous moving handling robot, and the track compensation is performed when the position is deviated. When the floor feature cannot be confirmed, the current position of the autonomous moving robot can be determined by the slam algorithm through the environment image captured by the binocular camera 57. In the course of walking, since the traveling mechanism provided by the second aspect of the present disclosure is used, the grounding pressure of the two driving wheels 21 can be ensured, and the traveling direction of the autonomous moving handling robot can be ensured. The ground distance detecting device senses the road condition ahead, and once the pit or obstacle is found, the control system controls the autonomous moving handling robot to stop walking and alarm. Meanwhile, if it is detected by the first obstacle avoidance sensor 114a and/or the second obstacle avoidance sensor 114b and/or the third obstacle avoidance sensor 58 and/or the collision sensor that there is an obstacle in the traveling direction of the autonomous moving handling robot, the control system will Control the autonomous mobile handling robot to immediately stop walking and alarm. Further, if the foup box on the carrier 5 is taken away, the control system controls the autonomous mobile handling robot to immediately stop walking and alarm after the signal transmitted from the target object detecting means 54.
