Embodiment
[0071] 1. The calculation process of the maximum walking distance of the dredging robot:
[0072]
[0073] Because the general size of the shaft is 300mm, if the volume of silt stored by the robot is the largest, then
[0074] V 淤泥 L max =V max
[0075] which is:
[0076] 2. BP neural network calculation:
[0077] e ij = r ij / r ij
[0078] That is, the reciprocal matrix E=(e ij ) n×n but
[0079]
[0080] After 3 iterations, w (3) =[0.159 0.170 0.170 0.042 0.127 0.098 0.130 0.068] T
[0081] Iteration accuracy is 0.001
[0082] Completion criteria for neural network BP algorithm (backpropagation algorithm):
[0083] In the sample set, each sample learns once, calculates the 2-norm of the expected output and the actual output, and accumulates it to the cumulative norm,
[0084]
[0085] After an epoch is completed, each sample is learned once, and the norm is accumulated at the same time,
[0086] E=0.05
[0087] Final distance traveled calcu...
