HOW DOES A ROBOT WORK?

A robot works automatically or guided by 1. .

Robotic arm: mechanical 2. programmed to repeat tasks 3. and safely

Parts:
• controller: (hardware) brain, connects arm to 4.
• 5. (electric, hydraulic, 6. ): engine, moves the links
• arm (steel or 7. ): base and joints, moves upon 8.
• end effector: hand, manipulates 9.
• 10. : receive feedback and signals

Control system: (software) manages 11. and tasks.
Paths:
• point-to-point path: between two 12. (for highly 13. tasks)
• continuous path: 14. path (several points in close proximity)

6. Listen to a recording about the importance of robotic arms in medicine and fill the gaps with the missing words.

1. In medicine, robotic arms offer , safety, and efficiency.
2. Robots assist and nurses in performing tasks that require extreme accuracy.
3. Robotic arms are transforming and improving patient outcomes.
4. In surgery, they make very small, precise that are difficult for human hands to perform.
5. Robotic arms can make little cuts instead of large .
6. In laboratories they perform repetitive or delicate tasks, reducing human and saving time.
