Answer: ABCD.
Answer Analysis:
Industrial robot safety considerations include the following:
When separating pneumatic systems, the air pressure should be released first. In industrial robots, pneumatic systems are one of the commonly used driving methods.
When it is necessary to separate the pneumatic system, the residual gas in the system should be released first to avoid air pressure damage Option A.
Before the repair work, it should be confirmed that the robot is not in a dangerous state. In the operation of industrial robots, it is necessary to ensure that no people are present in the robot's range of motion.
If there are people within the robot's action range, automatic operation should be prohibited to avoid safety accidents.
When multiple people work next to the robot equipment, please be careful not to block each other's escape routes.
When working next to industrial robot equipment, multiple operators are often present at the same time. At this point, it is necessary to ensure that everyone has enough escape routes to avoid blocking each other's escape routes in the event of an emergency and causing casualties.
So, depending on the title, the answer is ABCD.
