【Robot manipulator structure】

Through the use of modern design methods such as finite element analysis, modal analysis and simulation design, the optimal design of robot manipulator is realized. Explore new high-strength lightweight materials to further increase load / weight ratio. For example, a robot company represented by KUKA in Germany has changed the robot's parallel parallelogram structure to an open chain structure, expanding the working range of the robot, and the application of the light aluminum alloy material greatly improves the performance of the robot.

In addition, the use of advanced RV reducer and AC servo motor, robot operation machine almost become maintenance-free system. Institutions toward the modular, reconfigurable direction. For example, the joint module in the servo motor, reducer, detection system three integrated; by the joint module, connecting rod module structure using the restructuring of the robot machine; foreign have assembled modular robots to ask the market. Robot structure is more dexterous, the control system is getting smaller and smaller, both are moving toward integration. The use of parallel mechanism, the use of robotics technology to achieve high-precision measurement and processing, which is robot technology to CNC technology to expand, in order to achieve the future integration of robotics and numerical control technology laid the foundation.

【Robot Control System】

Open, modular control system. To the PC-based open-type controller in the direction of development, to facilitate standardization, networking; increased device integration, the control cabinet daily small, and modular structure; greatly improve the system reliability, ease of operation and maintainability . Control system performance to further improve, from the past control standard 6-axis robot to now able to control 21 or even 27 axes, and to achieve the software servo and digital control. Man-machine interface more friendly, language, graphical programming interface is under development. The standardization and networking of robot controllers, as well as PC-based networked controllers, have become the research hotspots. Programming technology In addition to further improve the operability of online programming, the practical application of offline programming will become the research focus, in some areas off-line programming has been put into practical use.

Robot Sensing Technology

In addition to using traditional sensors such as position, velocity and acceleration, assembly and welding robots also employ laser sensors, vision sensors and force sensors, as well as automatic tracking of welds and automated production of objects on the line Automatic positioning and precision assembly operations, greatly improving the robot performance and environmental adaptability. Remote robots use visual, acoustic, force, tactile and other multi-sensor fusion technology for environmental modeling and decision-making control. To further enhance the intelligence and adaptability of robots, the use of multiple sensors is the key to solving the problem. Its research focus is on effective and feasible multisensor fusion algorithms, especially in the case of non-linear and non-stationary, non-normal distribution of multi-sensor fusion algorithm. Another problem is the practical application of sensing system.

【Network communication function】

The latest robot controllers from YASKAWA in Japan and KUKA in Germany have realized the connection with Canbus, Profibus bus and some networks, making the robot a big step forward in networked applications from independent applications in the past. It also makes the robot from past special equipment Development to standardized equipment.

【Robot remote control and monitoring technology】

In some high-risk environments such as nuclear radiation, deep water, toxic and other welding or other operations, the need for remote robots instead of people to work. The development of contemporary remote control robot system is not the pursuit of autonomous systems, but committed to the operator and the robot's human-computer interaction control, that is, remote control plus local autonomous system constitutes a complete monitoring remote control operating system, intelligent robots out of the laboratory into practical stage. The sojourn robot that the United States launched onto Mars was the most famous example of the successful application of such a system. Multi-robot and operator coordination between the control, through the network to establish a wide range of robot remote control system, in the case of delays, the establishment of pre-display for remote control.

Virtual Robot Technology

The role of virtual reality in robots has evolved from simulation and rehearsal to process control, such as manipulating robots with the feel of remote robotic operators creating exposure to remote working environments. Based on multi-sensor, multimedia and virtual reality and telepresence technology, the virtual teleoperation and human-computer interaction of robots are realized.

【Robot cost performance】

Robot performance continues to improve (high speed, high accuracy, high reliability, ease of operation and maintenance), while stand-alone prices continue to decline. Due to the rapid development of microelectronic technology and the application of large scale integrated circuits, the reliability of the robot system has been greatly improved. The reliability of past robot systems MTBF is generally thousands of hours, but now has reached 50,000 hours, to meet the needs of any occasion.

Multi-Agent Control Technology

This is a new field of robotics research. Mainly on the multi-agent community structure, mutual communication and negotiation mechanism, perception and learning methods, modeling and planning, group behavior control and other aspects of research.
