Virtual Commissioning is…
The process of using simulation technology to validate PLC logic before making changes to the actual plant
The reason for using Virtual Commissioning is…
to unlike the traditional approach enable concurrent engineering in the commissioning of your plant
Why did Airbus decide to use Virtual Commissioning for the building of all their new factories?
It is a way to make sure their Tier-1 suppliers test all their logic programming on the equipment to be deployed in the Airbus factories.
What is the long-term goal of using Machine Learning in industrial robotics?
To increase flexibility in the tasks that robots are executing WITHOUT having to re-program the robot
What is the third main point for machine learning in industrial robotics?
To teach the robot how to work in a new environment is not longer necessary
What is the purpose of the Virtual Robot Controller in RRS? (Realistic Robot Simulation)

What is the definition of a robot?
It is a mechanical or virtual artificial agent
What is the definition of an industrial robot?
It is reprogrammable
Why do you buy an industrial robot?
It will help you to achieve higher quality through higher repetitiveness
What is TCP0?
It is the coordinate where you mount an end-effector
What is a revolute joint?
It is the rotational movement between two links
What is the homogenous transformation matrix?
It describes both rotation and translation
What is the name of the first industrial robot?
Unimate
Why was the electric robot important for the evolution of robots?
The resolution in robot movement was increased

Why did Joe Engelberger “The father of robotics” have problems to sell Unimate at the start?
Customers did not understand and industry was afraid it would take jobs from employees
Which three are joint types in a robot?
Ball-joint
Revolute joint
Universal joint
What is the purpose of a fixture?
A fixture is a device for locating, holding and supporting workpieces during manufacturing operations
What is the flag unit in a fixture?
It goes between the Structure of the fixture and the Pickup
How can jigs be eliminated?
In CNC machines the tool path is digitally programmed and stored in memory, thus can be utilized instead of jigs
How can fixtures be eliminated?
By robots to hold the part instead of putting the parts in a fixture
What is the 3-2-1 method in fixture design?
A workpiece is confined when banked against three points in one plane, two points in another plane, and one point in a third plane
How many elements of the degrees-of-freedom does the 3-2-1 principle give?
9
What is absolute accuracy?
Absolute accuracy is about going accurate to an unknown position
What does calibration of a robot do?
Robot calibration is the process of identifying certain parameters in the kinematic structure
What is giving bad accuracy?
Internal loading and structural resonance affecting the robot path
Why is an industrial robot risky to use in a grinding process?
Due to bad stiffness in the servos the robot will not maintain its calculated position
What is skidding effect in a robot?
It slides on the surface
