Deformable multi-mode ground and air flying robot

Abstract

A deformable multi-mode ground and air flying robot comprises a body, an automatic pilot, wing arm devices, hub devices and a suction device. The body is provided with the four sets of wing arm devices in a cross shape. The wing arm devices comprise large wing arms, small wing arms, rotation joints, installation supports, motors and damping sleeves. The hub devices are installed on the four sets of wing arm devices respectively and are driven to run through motors. The suction device is installed on the upper portion of the body and used for being sucked to the surface of an object with the assigned angle. The automatic pilot is installed on the body and drives the hub devices and the suction device to run. The automatic pilot drives the rotation joints of the wing arm devices to rotate so that the small wing arms can drive the hub devices to rotate to the assigned angle, and thus switching of a flying mode and a ground walking mode is achieved. The deformable multi-mode ground and air flying robot has the advantages of being low in power consumption, high in environment adaptability and multi-task handling capability, good in structural stability and high in mobility, and is suitable for multi-mode operation and capable of meeting various task requirements under various complex severe environments.

Description

technical field [0001] The invention relates to the field of mobile robots, in particular to a deformable multi-mode land-air flying robot in complex and harsh environments. Background technique [0002] At present, many application fields such as military reconnaissance, urban security, and disaster rescue require robots to have strong environmental adaptability and multi-task processing capabilities in complex and harsh environments, and it is difficult for a robot with a single motion mode to meet these requirements at the same time. For example: ground mobile robots have good reliability and load capacity, but it is difficult to complete tasks such as overcoming obstacles and wading; multi-rotor aircraft has good stability and maneuverability, but the battery life is short, and it is difficult to complete long-term work . Therefore, integrating the advantages of various motion modes to study multi-modal robots has important theoretical significance and application value...

Problems solved by technology

[0003] At the current stage, there are very few studies on multi-modal robots at home and abroad, and there are obvious limitations in applying them to complex and harsh environments.

Seaplanes can realize water-air amphibious operations, but most of them are used in open water, which is difficult to apply in local narrow areas such as urban security and disaster rescue, and cannot complete ground operations; application number 201410716895.9 is an invention named "Land-Air Amphibious Robot" Patent, designed a land-air amphibious robot with coaxial dual propellers and incomplete wheels, but the stability of the flight mode of the helicopter configuration is far less than that of the multi-rotor configuration, and the connection between the land device and the flight device is simple and direct. The connection also increases the weight of the robot and reduces the payload; recently, the University of California, Berkeley studied a robot that uses the robot cockroach VelociRoACH to carry the robot bird H2Bird. The robot cockroach uses the ground moving speed to provide the initial velocity for the robot bird to take off, but This is essentially the combined use of two robots, rather than the "amphibious" function of one robot, and the robot bird is small in size and requires a lower take-off speed
