1. Payload
The payload is the weight that the robot can carry. The load of cobots is generally between 3-20kg. All robots have a specified payload that does not include the weight of the end effector (such as a fixture) or auxiliary tool. This means that the actual payload that a robot can carry must subtract the weight of the end effector, such as a fixture, from its nominal payload. If an in-depth analysis of the robot's application is carried out, taking into account the practical application requirements (e.g., acceleration) and physical parameters (e.g., coefficient of friction), it is necessary to appropriately reduce the maximum payload of the robot. As in general motion control systems, the load mass is reduced in order to improve the dynamic characteristics (acceleration) of the system.
2. Weight
The weight of the robot's body means whether it can easily move and change the working position, or whether it needs a forklift or forklift AGV car to do the job. In some workshops, robots need to constantly change jobs to complete various production tasks. If the robot is too heavy, it will require more manpower and working time to complete the displacement and fixation of the robot.
3. Repetitiveness
Many times, people ask about the accuracy or accuracy of the robot's movements. But in the world of cobots, this metric doesn't really make much sense. In fact, what we need to know is repetitiveness. Since cobots are typically programmed and planned through manual trial teaching/manual guidance, the robot's ability to replicate and perform the exact same movements and locate x.y.Z coordinates with millimeter accuracy is more valuable. Currently, the maximum repetition values for most cobots are listed in the spec sheet. As a result, when we test and use robots, we often get less repeatability than their nominal values.
4. Security
Safety is particularly important for cobots due to the need to integrate with humans and machines. While safety is a very complex issue, many robot manufacturers still calibrate their robot products according to the appropriate safety level, and most of them will receive safety certifications issued by third parties. Currently, the most stringent machine safety approval process is t? V。 The organization has approved safety certifications for many robots. At the same time, there are many different variables for the "safe" certification of robots. The only thing that needs to be explained is that the authentication of the robot is secure, which does not mean that the application of the robot is secure.
5. Ease of use
There is often a need to work with people. Cobots often switch between different operating tasks, and the ease of use of programming and configuration directly determines the production and operation efficiency of the equipment application. But this metric is actually very difficult to quantify. Because it is very dependent on people's operation and usage habits. The same interface or usage method is easy for some people, but difficult for others. Therefore, this indicator is always subjective.
6. Reach
The reach of a robot refers to the maximum (long) distance that the robot's wrist can reach. This distance is usually measured from the bottom of the robot. At the same time, there are many ways to measure the span of a robot arm. In most cases, we choose the maximum distance that the robot's wrist can reach as a reference. Typically, the arm length of a cobot is equal to the length of a human arm.
