Fall-proof wheeled robot and fall-proof method

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...

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 and the wheels also need to maintain a certain installation distance, which greatly limits the appearance design of the robot, and because of the balance Therefore, the center of gravity of the robot must be moved backwards to keep the robot from falling easily

[0004] Therefore, the wheeled robot anti-fall method of the prior art is difficult to detect a large distance to brake to achieve the purpose of anti-fall
