At present, the dual-arm robot has begun to be used in the 3C electronics industry, although the current price in several hundred thousand yuan a, but his workload is equivalent to two single-arm robot, and flexibility, cooperation is higher, more suitable for part of the flexible process, but also the 3C electronics industry, human-machine cooperation better interpretation.
Compared to multi-axis single-arm robots, dual-arm robots are still in the stage of competition between large enterprises. The emergence of dual-arm robots is not just a simple combination of two single-arm robots, but a coordinated control of the two arms to complete the corresponding work. In the future of industrial production dual-armed robots will play an increasingly important role. Especially in the field of 3C robotic electronics, the advantages of dual-arm robots will be more obvious.
Advantages of dual-arm robots
Single-armed robots have many limitations due to the compactness of electronics, rapid update cycles, and performance requirements. Dual-arm robots are just like human hands, requiring only one controller to synchronize and coordinate the movements of both arms and to achieve flexible trajectories, thus providing a highly flexible operating space and effectively overcoming the problem of multiple single-arm robots interfering and colliding with each other on the production line. Because the dual-arm robots complement each other, the number of robots on the production line can be reduced, lowering production costs.
Dual-arm robots are particularly suitable for component assembly in the 3C electronics industry. Small quantities, diversity, and customization have become the current trend in 3C product lines. The dual-arm robot is highly independent and does not require separate tools on the production line, so when the production line changes, only the fixture at the end of the dual-arm robot's arm needs to be replaced, which is highly flexible.
Development of dual-arm robots
Foreign research on dual-arm robots began in the 1990s, and the earliest research work focused on the trajectory planning of the dual-arm robots, which was more based on how multiple robots would not collide with each other in the same work environment. In the research of two-armed robots, researchers in the United States and Japan have made many technical breakthroughs in the research of two-armed robots with the support of advanced manufacturing technology and means and strong research funds. In contrast, domestic research on two-armed robots started relatively late, mainly involving motion trajectory planning, dynamics, and coordination control.
Double-armed robots will play an important role in industrial automation, and the main manufacturers involved in double-armed robots are ABB, KUKA, YASKAWA, Kawada Industries and Fujikoshi. Last September, ABB released YuMi, the world's first truly human-robot collaboration, a two-armed robot designed with humanized visual and tactile functions to achieve perfect human-robot collaboration. YuMi is highly sensitive and extremely flexible, making it suitable for a wide range of precision work. In addition to being able to work well with people, it can also work in coordination with machines at the same time.
It is reported that the dual-arm robot has already started to be used in the 3C electronics industry, and although it is currently priced at several hundred thousand yuan a piece, its workload is equivalent to two single-arm robots, and it is more flexible and cooperative, which is more suitable for some flexible processes, and it also interprets the human-machine cooperation in the 3C electronics industry better.
