Test Flashcards
What are end effectors?
Devices attached to the wrist of an Industrial Robot.
What type of movements do Pick and Place operations require?
Movements that do not require particular finger dexterity or use of the opposed thumb.
What are end effectors that perform prehensile movements called?
Grippers.
What is often used to construct a simple gripper?
A pair of two-finger grippers.
What does a suction gripper consist of?
One or more suction cups made of natural or synthetic rubber.
What device should be installed to prevent damage to a robot’s arm or wrist?
A device that prevents damage if the end effector becomes stuck during an operation.
What may a robot be equipped with to compensate for misalignment or irregularities in a workpiece?
A compliant device.
What are Odea Cylinders used for?
