INDUSTRIAL ROBOTICS

Industrial robots are programmable machines designed to perform tasks in factories and 1. .
They have degrees of 2. : independent movements of a 3. (one possible direction or type of motion)

Typical independent movements:
• 4. rotation
• shoulder movement
• elbow movement
• wrist 5.
• wrist yaw
• 6. roll

Types of industrial robots:
• articulated robots: three 7. joints in a chain (8. , painting, welding)
• SCARA robots: manipulators, four 9. (for pick and 10. tasks)
• 11. (Cartesian) robots: manipulator onto overhead system, movement across 12. plane (for CNC machines, welding)
• cylindrical robots: primary arm, axes form 13. coordinate system (for machine loading)
• spherical robots: 14. base + two rotary joints + linear joint, telescopic 15. (for assembly lines)
• delta robots: 16. robots (for high-speed electronics, packaging, sorting)
8.1 Say if the sentences are true (Vero) or false (Falso).
1. Industrial robots help humans by doing dangerous and repetitive jobs.
2. Normally, industrial robots have more than six DOF.
3. The wrist yaw refers to the up and down movement.
4. Articulated robots have a chain-like joint structure.
5. SCARA robots are used for pick and place tasks.
6. SCARA robots can also be called Cartesian.
7. Gantry robots usually move along a vertical plane.
8. The axes of cylindrical robots form a cylindrical coordinate system.
9. Cylindrical robots have a telescopic axis to reach long distances.
10. Delta robots are used for high-speed tasks.
