Embodiment Construction

[0042] The embodiment of the present invention is a deformed mobile robot, the length of the body 001 is 648mm, the width of the body 001 is 450mm, the length of the thigh 002 is 360mm, and the length of the shank 003 is 262mm, take X dMax It is a quarter of the length of the entire fuselage 001 when the robot is fully extended: 473mm, take Y dMax It is the height of the center of gravity of the whole fuselage 001 when standing at the highest point: 622mm, and the rotation angles of each joint are respectively calculated as integral multiples of 90° or 45°.

[0043] In order to find the best way of robot posture deformation described in the embodiment, adopt the present invention to determine the process following program of its posture best deformation way:

[0044] The first step is to establish the 8 possible deformation poses of the deformable mobile robot, and take a name code corresponding to the vertices of the graph theory, as shown in Table 1, and the corresponding ei...

Abstract

The invention discloses a determination method for a shape shifting robot attitude transformation optimal path. According to the determination method for the shape shifting robot attitude transformation optimal path, the graph theory is introduced on the attitude control of a shape lifting robot, an attitude transformation problem is converted into a graph theory related problem, accordingly, according to the attitude transformation complexity weight minimum principle, when the optimal attitude transformation path is obtained, a control system can send a corresponding driving order to a motor of each joint of the shape shifting robot, so that the shape shifting robot can transform the joint turning angles of the shape shifting robot in sequence according to the optimal attitude transformation path, the reasonable sequence transformation of the attitude of the shape shifting robot is achieved, the interconversion between different attitudes is achieved, for different environment conditions, the attitude transformation of the shape shifting robot can be achieved stably, efficiently and reasonably, and therefore the good environmental suitability is achieved.

Description

technical field [0001] The invention relates to a deformed robot, in particular to a deformed mobile robot. Background technique [0002] There are more and more researches on deformable robots in different complex environments, especially deformable mobile robots, and there are more and more robot deformable poses. For example, a deformed mobile robot has four crawlers (belonging to the lower leg) with drive motors, and each crawler is connected to the main body of the robot through an extension rod (belonging to the thigh) via two kinematic joints, and each kinematic joint uses a motor drive. Through the rotation around its joints, each calf and thigh can achieve rotation changes at different angles, thus combining various postures of the deformed mobile robot, realizing its different walking modes, so as to adapt to the movement needs of different environmental conditions . In the posture transformation of the deformable mobile robot, the transformation between some po...
