This paper presents a method of target tracking based on convolution neural network and texture feature fusion. The lower layer of the convolutional neural network can extract some spatial structure, shape and other features of the target. High-level level can extract relatively abstract semantic information. In this paper, vgg-m convolutional neural network is adopted to realize tracking by adaptive fusion of the extracted depth features of Conv2 and Conv5 with the texture features extracted by two-dimensional Gabor filtering. In this paper, the experimental analysis of this method is carried out on the OTB2013 data set, and the results show that this method can achieve more accurate positioning of the target and has a strong timeliness.

Traditional series robots have the disadvantages of complex structure and complicated control. Almost all of them have no adaptive ability. Although soft robots have good adaptive characteristics, they also have the limitations of poor bearing capacity and low stiffness. In addition, their motion trajectory and motion precision are difficult to achieve accurate control. In order to solve the above problems, based on a single motor-driving multi-stage metamorphic mechanism, this paper carries out kinematic analysis and error analysis to determine the motion trajectory and motion accuracy of the multi-stage metamorphic mechanism. And this paper uses ADAMS to carry out simulation calculation. Comparing the theoretical calculation results and simulation calculation results, and determining the errors between the multi-stage metamorphic mechanisms, so as to ensure the accurate position of the multi-stage metamorphic mechanism during work. The multi-stage metamorphic mechanism realizes stable and efficient work.

Aiming at the challenging frontier problem of umbilical cable properties theory, which has been puzzled by this kind of robot for many years but has not been solved yet, this paper proposes an umbilical cable properties modelling method based on Kirchhoff elastic bar theory. This method analyzes the force on the umbilical cable member in the equilibrium state, obtains the Kirchhoff equation of the mobile cable in the equilibrium state, and then establishes the physical characteristics model of the mobile cable, and obtains the form of umbilical cable and the stress on the end point by solving the model. The new modelling theory research on the physical characteristics of deep-sea umbilical cable carried out in this paper is expected to solve the problem of 'unclear' problems of deep-sea slender umbilical cable, get rid of the dilemma of 'blind man and elephant', and provide guarantee for the safe and efficient operation of deep-sea robots.
