[0021] The present invention will be described in detail below in conjunction with specific implementation cases.
[0022] The present invention is a coordinated navigation and positioning algorithm for multiple mobile robots based on CKF and VCE methods. figure 1 The algorithm flow diagram shown, and its specific implementation is as follows:
[0023] Step 1: First, build a reasonable working environment according to the tasks of the multi-mobile robot, determine the fixed landmark points in the surrounding environment of the multi-mobile robot, and measure the position of each fixed landmark point in the working environment and the initial position of each mobile robot And posture information;
[0024] Step 2: Construct a state vector including the position and posture of multiple robots:
[0025] X=[X 1 X 2 … X n ] T
[0026] Where X i =[x i ,y i ,θ i ] T Represents the pose of the i-th robot, which can be expressed as:
[0027]
[0028] Construct a measurement vector including dis...
