Machine vision obtains the three-dimensional cloud point information of the shape and displacement of the object and communicates it to the control system. Through the feedback of the pressure sensor, the robot controls the intensity according to the surface change to achieve precise polishing.
Recently, Gartner, a global information technology research and analysis organization, summarized the top ten strategic technology trends in 2014, and proposed that the intelligent machine era will become the most subversive era in IT history, saying that smart machines will accelerate consumerization. Xiao Y, a polishing robot with sensors, is a vivid example of the high intelligence of intelligent machines.
The intelligent machine sounds far away and has been gradually applied around. Researchers at the Institute of Precision Sports and Advanced Robotics of the Chinese Academy of Sciences, Zhang Chi, said that whether it is home products, manufacturing equipment or robotics, we are bringing us into an increasingly intelligent era.
Xiao Y is a polishing robot that exists in the robot team's vision. It represents the hotspot of international research, that is, how to collect and store the knowledge and experience of skilled technicians through various sensors, machine vision, etc., form an expert system to teach robots, let robots simulate human actions, and reach skilled workers. The effect of the operation.
Highly intelligent robots involving multiple disciplines are difficult to implement. Zhang Chi said that this is a hot spot in international robot research. For a long time, the polishing process has been mostly done by manual processing, which is time-consuming, labor-intensive, and has poor product consistency. Therefore, the demand for automatic polishing equipment is growing, and this demand exists in many industries and fields. For example, in the Philips factory in the Netherlands, electric razors are assembled using 128 mechanical arms.
Using robots to defeat people is one of the ways in which the US re-industrialization strategy. In China, upgrading traditional industries with modern and automated equipment is also an objective requirement for promoting industrial upgrading. During the 12th Five-Year Plan period, China's industrial robot industry market demand will grow at a rate of 15% to 20% per year. The International Robot Federation expects China to become the world's largest robot market by 2014.
In this context, the robot team focuses on R&D. Recently, the force-controlled polishing robot led by researcher Xia Qinghua has made important progress, and the second-generation prototype has completed preliminary debugging. It can imitate the operation of the worker polishing the workpiece, and maintain the constant force contact between the polishing tool and the processed workpiece by controlling the contact force, effectively guaranteeing the polishing quality and realizing the automation of the workpiece polishing.
The integration of new technologies such as industrial robots and vision, as well as multi-source sensor information fusion technologies, is moving toward a more intelligent direction. Zhang Chi said that the technology is also in the application research stage in the world, and Xiao Y is the future sample of polishing robots.
