It is a challenging task for a manipulator to grasp sea cucumber on the seabottom, because it is difficult to determine the sea cucumber grasping angle of the manipulator. In this paper, a method for determining grasping position and angle of sea cucumber by rotatable bounding box is proposed. Firstly, an improved full convolution image segmentation network model is proposed. Secondly, the expanded sea cucumber image is used to train the improved full convolution neural network. Thirdly, we use the trained neural network to segment the image to get the sea cucumber target. Finally, the grasping position and angle of sea cucumber are determined according to the minimum enclosing rectangle of the largest connected region of the segmented image. Experiments show that the improved full convolution image segmentation network model can effectively improve the accuracy and speed of sea cucumber target segmentation. The proposed method can determine the grasping position and angle of sea cucumber at any rotation angle in real time and accurately.

This paper discusses the dynamic load-bearing capacity of the main transmission mechanism of worm pair traction machine in a cargo lift. By fully considering the mass, rotational inertia and friction for transmission of the worm pair, multi-body dynamics was adopted to calculate the worm gear teeth contact force and motion characteristics. Based on the nonlinear finite element algorithm for friction-contact and combined with the dynamics computation results, the finite element calculation for the teeth contact strength and bending strength were performed. The finite element calculation results and theoretical calculation results were compared to analyze their difference. The mechanism quality was evaluated from the running stability and mechanical strength, and the evaluation results show that the main transmission mechanism of traction machine in the cargo lift has good dynamic load-bearing capacity and high safety, and meets the design requirements.

How to play the role of the college training base in the process of talent training? In this paper, the national comprehensive training base of Suzhou Vocational University was taking as an example. It has been proposed that the talent training mode and three layer practical framework for the comprehensive training base of IoT.
