Selection of end-of-arm tools for collaborative robots suitable for their needs need to consider the following factors:

1. application needs: first of all, you need to clarify their application needs, such as the need for fine assembly, material handling, welding, etc., different application needs require different end-of-arm tools.

2. working environment: the working environment is also an important factor in the selection of end-of-arm tools. For example, if the working environment is narrower, you need to choose a smaller end tool; if the working environment exists higher temperature, humidity or corrosive gases, etc., you need to choose to adapt to these environments of the end of the tool.

3. Load capacity: the load capacity of the end tool is also an important factor in the selection. Need to choose the appropriate load capacity of the end-of-tool according to their own application needs, to avoid insufficient load capacity and lead to the robot can not complete the task.

4. control mode: end-of-tool control mode also needs to be considered. For example, some end-of-arm tools can be realized through manual control, while others need to be realized through software control.

5. Cost factor: Finally, the cost factor also needs to be considered. Different end tools have different prices, and you need to choose the right end tool according to your budget.

To summarize, choosing the end-of-arm tool for collaborative robots that suits your needs requires comprehensive consideration of application requirements, working environment, load capacity, control methods and cost factors.
