Robotic arms is one of the representation of the industrial automation products, with more and more get attention automation technology research and development of robotic arms industry starts to increase. It is worth noting that in active perception technology increasingly popular, plus software tools have made great progress, the wisdom of the robotic arms have the obvious progress, whether large arm or collaborative, is becoming more and more easy to operate, perception changes significantly improve the capacity of the surrounding environment.
Workers being intelligent robot technology by mechanical way ChangYou hon said, industrial production growing demand for robotic arms, how to make the machine arm more secure, more easy to operate, will be the main direction of future robotic arms technology. Published in security, as the ISO ISO/TS15066 specifications, safety requirements for collaborative robot made specific provision, future robotic arms carrying a perceptual technology, in order to detect the movements in the environment, will be the trend of product design.
ISO/TS15066 for collaborative design and installation of robot made detailed requirements and risk assessment criteria, its main focus has four: a robotic arm, people touch, to immediately stop arm action; Second, the robot arm can be guided by people directly to record its operation path; Third, if there are working in the personnel or other object into the machine arm, robotic arms should automatically slow down to ensure safety; Fourth, the strength and power of the robot arm must be within the limits.
Engineering institute in 2015, has been working with silver, develop Taiwan's first security collaborative robotic arms, and in accordance with ISO/TS15066 specification. On this basis, engineering institute in 2016 to further develop can be mounted on the existing robotic arms touch the skin and the sensor mat modules, can let is currently not sensor staff activities surrounding the machine arm also has a certain degree of awareness, and adjust the operation speed and improve security.
YouHong analysis, there are a lot of technology can be used to achieve secure cooperation specification requirements of the robot, in addition to the most basic ability of tactile sensor, some vendors based on laser ranging light or image sensor technology to implement security alert function, but workers being considered, let the machine arm near the floor of the pressure measuring ability, can detect whether the people or objects into the alert zone, is a minimum problem, and also the most intuitive solution, and its technical principle and touch the skin is the same, the system is relatively simple.
UniversalRobot (UR) in the automation, robotic arm also shows a series of collaborative application, containing combination pick application of machine vision, the surface of an object in curved surface polishing, etc. UR area technical support supervisor AndrewPether said the cooperation security function is UR machine arm standard function, in addition to outside the resistance will cease to function completely, also can match the other sensor technology, dynamic speed adjustment. Its is the most typical applications, the operational areas when someone close to the machine arm, arm will automatically slow down to ensure safety; When working in the personnel leave, robotic arms will return to normal speed.
German industrial giant Bosch (Bosch) although there is no in the automation show their robotic arms, but Bosch no absence in the field of collaborative robot. Bosch rexroth factory automation assistant manager Chen Junlong said, compared with other companies to arm Angle to think about product research and development direction, robotic arms Bosch as a human employee's personal assistant to look at, so Bosch APAS, robotic arms in addition to possess a sense of touch the skin, laser security functions such as close to the sensor, the user can also push APAS around to do different things. User as long as your arm to positioning, through the simple dialogue window set, you can adjust the arm work content. The arm has a built-in 3 d machine vision function, can accurately identify the contact object type.
In fact, the action of the machine arm may be the future worth looking forward to the direction of the machine arm. In the automation, automatic guide vehicle (AutomatedGuidedVehicle, AGV), namely, commonly known as the handling robot, is also the focus of the show quite eyes absorption. Now AGV is mainly used in logistics, which can be carried out in accordance with the program setting and planning in advance good track inspection, loading, discharge of the goods, but also have the manufacturer will be installed directly on the AGV, collaborative arm in order to make AGV more diversified missions.
