Problems solved by technology

[0003] The main defect of the prior art is that the detection sensitivity of the analog infrared transceiver module is low and is easily disturbed, so the general detection distance is not very far, about 10cm, which is enough for robots with this layout, but It is very limited in appearance, the wheels must be behind the detection module, and because a braking distance is required, the detection module a...

Embodiment Construction

[0021] In order to make the present invention more detailed, it will now be explained in conjunction with the accompanying drawings and embodiments.

[0022] like figure 2 As shown, the wheeled robot 3 of an embodiment of the present invention is equipped with several infrared transceiver modules 1b, and the infrared signal transceiver direction of each infrared transceiver module 1b forms an acute angle with the horizontal plane, and the angle with the horizontal plane in the current embodiment is 45 degrees. In other implementation manners, the angle range between the infrared signal sent by the infrared transceiver module 1b and the horizontal plane is less than 90 degrees and greater than or equal to 30 degrees.

[0023] The infrared transceiver module 1b can be installed at any position of the robot. Using the diffuse reflection of the ground 2, the infrared receiving head in the infrared transceiver module 1b detects the received synchronous diffuse reflection signal, a...

Abstract

The invention discloses a fall-proof wheeled robot fitted with a plurality of infrared transceiving modules, and an infrared signal transmitting and receiving direction of each infrared transceiving module is acutely angled to the horizon. Correspondingly, the invention also discloses a fall-proof method of the wheeled robot, comprising: the wheeled robot inclining at an acute angle to the horizon to transmit a plurality of infrared signals, and stopping moving forward if not receiving the corresponding infrared signals that are reflected within a predetermined period of time. The fall-proof wheeled robot and the fall-proof method have the advantages that the use of an inclined infrared signal transceiving mode provides a widened detection range, effective fall prevention is thus achieved, and the appearance design of the wheeled robot is more flexible.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a fall-proof wheeled robot and a fall-proof method. Background technique [0002] In the existing technology, such as figure 1 As shown, most of the current anti-fall methods for indoor wheeled robots are to add an analog infrared detection module 1a in front of the robot wheels, and after the analog infrared detection module 1a receives the reflection from the ground 2, it thinks that there is a ground plane in front of it. , if no reflected signal is received, it is considered that there is a step ahead. [0003] The main defect of the prior art is that the detection sensitivity of the analog infrared transceiver module is low and is easily disturbed, so the general detection distance is not very far, about 10cm, which is enough for robots with this layout, but It is very limited in appearance, the wheels must be behind the detection module, and because a braking distance is r...
