13. Study the slide below, in pairs or small groups answer the questions

1. What are the most frequent jobs robots do in industry?

(to drill holes, to tighten bolts, to fill containers, to twist caps onto peanut butter jars, …..)

2. What end effectors would these jobs need? (use the prompts in the right-hand slide)

3. What end effector can you see in the picture?

4. Speak on how a pressure sensor works through the example of a gripper.

How Are Robots Used in a Factory? Robots in factories are used to: lift heavy items assemble parts together join parts together using glue or by welding paint things glue – клей welding – сварка

The robot's end effector depends upon the job that the robot has to do. It could be: a gripper (like a hand, for picking things up) suction pads (for lifting sheet metal or glass) a paint spray gun (for painting things) a welding gun (for joining metal parts together) suction pad – присоски welding gun – сварочный пистолет
