With the more and more extensive use of robottechnology in industrial production, the trajectory planning requirements of industrial robots are constantly increasing. In order to solve the problem that the trajectory is difficult to fit due to the nonlinearity in the continuous trajectory planning of robot, this paper presents a trajectory planning method of industrial robots which combines RBF (radial basis function) neural network and PSO (particle swarm optimization) algorithm. When RBF neural network has fewer hidden layer nodes, PSO algorithm is used to optimize the connection weight and threshold of RBF neural network. Through simulation analysis, the RBF neural network before and after improvement is compared. The results show that compared with the trajectory planning algorithm before improvement, the PSO-RBF neural network has smaller error and stronger adaptability, which meets the expected requirements of industrial robot trajectory planning.

In order to realize tight formation control of spherical robots, a formation control method of multi-spherical robot system was proposed based on optimization of pigeon swarm algorithm. Based on the kinematics model of spherical robots, the roles of spherical robots were divided into leader and follower. A PID controller was designed for stability control in x and y direction channels. According to the desired position and velocity, a corresponding fitness function is uniformly set to optimize the optimal parameters of the formation controller. Finally, the stable control of the multi-spherical robot formation is realized in the simulation environment.

In order to improve the motion stability and monitorability of inspection robots, a digital twin predictive control system for inspection robots based on Unity3D and robot Operating System (ROS) is proposed. Firstly, with the support of wireless communication technology and ROS system, the mapping of virtual-real space scene and robot state is carried out through TCP/IP protocol;secondly, considering the impact of data communication lag and signal loss on the control system, a predictive control model is constructed to control the robot's motion in order to reduce the reliance on real-time data, and the predictive control model is optimized by using Laguerre's function as well as filtering algorithm to optimize the control response and mitigate control oscillations in time;finally, in the virtual decision space, the physical robot is driven to follow the predicted trajectory in a synchronized mapping manner. The experimental results prove that the digital twin control system has good tracking performance and is stable and reliable. Compared with that before model optimization, the efficiency is improved by 50.93% and the error is reduced by 69.23%.

In the field of automated construction, the autonomous navigation system of construction robots plays an important role in improving work efficiency and safety. Visual SLAM technology has demonstrated its superiority in the dynamic scene of construction due to its strong adaptability and relatively low cost. Therefore, based on the characteristics of the construction environment, the traditional visual SLAM technology has been improved to enhance the positioning and map construction performance of robots. By combining RGB-D cameras with the ORB-SLAM2 framework, the accuracy of robot environmental perception and positioning has been improved, and the YOLOv4 tiny network has been used to eliminate dynamic interference and optimize the stability of the navigation system. The simulation results show that the autonomous navigation system for construction robots based on improved technology reduces path planning and travel time by 19.08% and 13.81%, respectively, and significantly improves the efficiency and accuracy of 3D map construction. This research achievement provides a new technological approach for precise navigation of construction robots, which is of great significance for achieving autonomous robot operations in construction scenarios.
