I have created a program to package the honeycomb of the genetic industry, but in the middle, I need to have the robot switch between the items in hand. I already know that there are other ways to achieve similar functions (such as continuous inventory detection, if there is no specific item, it can be considered that the robot has already held it), but I would like to ask if there is an API that allows for direct detection of items in the robot's hands? If any, this will significantly reduce the complexity of the program. Thank you:)
