Arm 14-axis robot Yumi

ABB Dual-arm 14-axis robot Yumi

UL (Underwriters Laboratories) announces that the global industrial robot brand ABB's dual-arm 14-axis robot Yumi obtains UL safety certification, highlighting its key security design with human-machine collaboration capabilities.

Industry 4.0 and the advent of advanced manufacturing era, the global intelligent robot business opportunities bullish, manufacturers positive card position, the first research and development focus on the safety and reliability of the robot. As a comprehensive development, robotic applications have moved out of the traditional robotic arm of simple movement in the production line, more can meet the fine, intelligent, complex, such as medical, care, electronic assembly applications, and even close collaboration with people, so the robot's "security Design" has become the highest priority and the most necessary consideration project.

Judging from the corresponding security certification, the robot must pass through the level level and each kind of practical safety assessment, from the traditional to avoid the electric shock, the fire protection main basic safety request, to the system security control functional safety assessment, but also needs to include the single point failure analysis, the use situation risk and the management strategy analysis and so on, In order to ensure that each security control link is not only available, but also reliable and durable, even if a single cause of failure, can still maintain a safe state.

UL Taiwan general manager Tang Jiade said, "The human-machine collaboration and the axis of many robot certification process complex, take Yumi's arms 14 axis as an example, there are 14 kinds of translational and rotational freedom of movement, with each other to produce more and speed of action, UL by virtue of professional experience in security, for the different applications of robots, Simulation of a variety of failure scenarios to ensure that the robot in every situation, not only to interact with people smoothly, but also to be able to detect themselves, maintain security and reliability. ”

ABB Taiwan Industrial Robotics Department head Cai Jingchun associate said, "Ansi/ul 1740 robot and automation equipment standards, not only commercial standards, but also the United States National Standards Association (ANSI) adopted the national standard, through the global credibility of the UL certification, Symbolic yumi security design through rigorous and objective evaluation and testing, can lead the global industry truly into the industry 4.0/advanced manufacturing. ”

This time, the world's first dual-arm industrial robot Yumi to obtain UL certification of robot security, for the robot to human-machine interaction to bring the significance of the indicators, but also to ignite the industrial kinetic energy for the sustainable development of the robot industry and the popularization of the application of a strong heart needle injection.

The huge business opportunities brought by robots have become the focus of the layout of many manufacturers in Taiwan and the world. Robots are one of the key priorities for Taiwan's government, which is expected to devote at least 4 billion yuan a year to 4.0 per cent of productivity projects. The European Union estimates that business opportunities for the global Android Market will be as high as € 60 billion in 2020, and Boston consultants are predicting that the global robotics market will grow to $67 billion from 2010, 2025 years ago, with robots becoming the global technology integration battleground for the next decade.

Advantages:

1. One-arm 7-axis redundancy design, 14-axis arms, coupled with small fuselage, light weight, very flexible, in the cooperative robot movement speed quickly;

2. Using ABB IRC5 Controller, rapid programming language, the function is very powerful, realizes the single controller to the arm coordinated control, ABB's SDK also provides the customization development possibility;

3. Debugging environment Robotstudio provides a powerful off-line debugging environment, and Cognex vision system integration is very good, embedded Cognex view of the Insight Easybuilder;

4. The official hand hand provides the servo grasping function, may provide the real-time grasping force and the grasping position feedback, may choose the vacuum sucker, and Cognex AE2 embedded Smart Camera (with Patmax);

5. The Contactl contact force control function is added, which can realize the action of triggering signal by the ambient contact force estimated by the joint torque;

Disadvantages:

1. The load is too small, single arm 500g (thanks Comment area correction) standard load limits its only applies in the lightweight work, also limits to the hand the custom development;

2. The function development related to the force control still needs to be perfected. At present, there is only one contactl function, which can make the robot detect whether the contact force reaches a preset value in the course of linear movement, and achieves the remaining action. Functional functions such as Force compliant installation, contact Force detection, constant contact force movement and so on have not been developed.

3. The joint torque is used to detect the contact force, so the sensitivity is good when the contact point is 4 to 6 axes, and the sensitivity decreases when the 1 to 3 axes are detected. In fact, all writing robots that detect contact force with joint torques have this problem.

The most important thing about this robot is its powerful control function, is a collaborative robot, in the face of people or other objects can stop, do not need to be like other industrial robots around, I have experienced the exhibition center in Shanghai Hongqiao, stop function, indeed very sensitive, the shell wrapped with a soft sponge.

Robot directly designed into arms, end load only 500 grams or 300 grams, anyway is very small, designed to do electronic parts assembly, such as light load function. The entire robotic arm is small in size and feels like the smallest of these new collaborations, and it can be converted into other service robots.
