Title: Bionic Control Method for Quadruped Robot Drive System
Abstract: This report begins by introducing the composition of electric quadruped robots and hydraulic quadruped robots, comparing the advantages, characteristics, and application fields of the two types of quadruped robots. Then, this report presents an overview of the neural composition and control principles of mammals, as well as the aspects of control methods in quadruped robots that draw inspiration from them. Then again, the report shares the principle and control method of our team’s quadruped robot motor drive control. Furthermore, a principle and control method for hydraulic-driven control of quadruped robots are proposed, forming a multi-layer framework and multi-layer coupled control method for hydraulic drive control. This method encompasses lower-level control for position and force control of hydraulic muscles and closed-loop control of pressure and flow of hydraulic heart, mid-level control for hydraulic compliance, compensation, and contact force control, and top-level control for posture planning. Lastly, it is envisioned that future advancements in the drive systems of quadruped robots should take a biomimetic approach that is more oriented towards the subconscious reactions and self-learning abilities observed in mammals.

Title: Research progress of the friction-based solid-state additive manufacturing technology
Abstract: Aerospace manufacturing industry, as a high-tech intensive industry, is the development direction of manufacturing industry all over the world, and its development can not be separated from metal components with the characteristics of light weight, difficult processing and high performance. Additive manufacturing (AM) opens up a new technological approach for designing and manufacturing high-performance metal components. However, conventional fusion-based AM methods, which involve material melting and solidification, drastically deteriorate the mechanical properties of these alloys by forming coarse grains, cracks, and pores. Friction-based solid-state additive manufacturing methods, such as friction stir additive manufacturing (FSAM), friction surfacing (FS), additive friction stir deposition (AFSD) and friction rolling additive manufacturing (FRAM) have been developed in recent years, which have great application potential in the field of manufacturing light alloy structures due to their forged microstructure characteristics and excellent mechanical properties. This report introduces the development and characteristics of various friction-based additive manufacturing technologies. The process mechanism, interlayer bonding behavior, microstructure and mechanical properties of FRAM are introduced. Finally, the potential engineering application and future development direction of friction-based AM technology are summarized.

Title: The mechanism and frontier applications of cavitation effect
Abstract: Cavitation is a process in which gas holes (vacuoles) in liquid or at liquid-solid interface form, develop and collapse when the local pressure in liquid is lower than the saturated vapor pressure. In the process of cavitation, local high temperature, high pressure, discharge, luminescence and shock waves are generated. Cavitation was first proposed by Barnaby and Parsons in 1897. At present, the main cavitation modes include hydraulic cavitation, jet cavitation and ultrasonic cavitation. Cavitation can be applied to the shot peening process, so as to reduce the cracking of materials caused by stress concentration and improve the corrosion resistance of materials. Our research group built cavitation jet shot peening equipment for cavitation shot peening, filmed the evolution process of cavitation cloud generated by cavitation jet with high-speed photography, and carried out numerical simulation and comparison with the shooting results. The influence law of process parameters on the range and effect of cavitation jet shot peening was determined by orthogonal experiment. Cavitation can also be applied to metal foil microforming. This research group uses the shock wave energy generated by submerged cavitation jet cavitation to design complex molds. By combining the incident pressure, target distance, and time of operation and other process parameters, the foil microforming method has been explored for its range and effect. The forming mechanism of metallic foil is studied by characterizing the experimental results. Due to the lack of micro-hole polishing technology, our research group proposed the alternate volume cavitation polishing technology, which changes the pressure in the closed volume by changing the volume size, so as to induce the cavitation effect to polish the surface of the micro-hole. This project verified the technical feasibility through high-speed photography and numerical simulation, and built an alternate volume cavitation test platform based on this. Cavitation can also be applied to other aspects, such as the preparation of boron nitride nanosheets.
