Q

What are the names of the 3 safety zones

A

The safe zone, the area where anyone can travel
The danger zone, the same as the work envelope for the robot , where OSHA requires you to have an E-stop in reach at all times
The cautionary zone, where you are close to the robot, but out of its reach, where the operator often works

Q

What are the numbers and names of the three orientational or minor axes? (Not X, Y, Z)

A

Axis 4 – Pitch (Up and down movement of the human wrist.)

Axis 5 – Yaw (Side to side movement of the human wrist.)

Axis 6 – Roll (Rotation of the human wrist.)

17
Q

What are the steps of the LOTO process, in order they are executed?

A

1 Notify affected individuals you are about to shut the machine down
2 Stop the machine cycle if necessary
3 Turn off or remove all external power supplies and lock them in the off positions
4 place appropriate information tags on the equipment
5 Verify a zero-energy state.
6 perform the necessary actions

7 Once the repairs are finished, remove all tools and any blocking devices

  1. Once everything is clear, each person working on the robot should remove his or her own lock
18
Q

Between DC current and AC current electrical systems, which is the more common choice for the for the electric Motors used in Industrial Robotics?

A

AC is a common choice for industry and drives both stepper and servomotors

19
Q

Is hydraulic power used to move heavy or light loads in industrial robotics?

A

Hydraulic power is used to move heavy loads.

20
Q

What is Pneumatic power commonly used for in industrial robotics?

A

Pneumatics are commonly used to power robot tooling

21
Q

Name the 7 options used when classifying industrial robots based on the geometry of their work envelope.

A

Cartesian
Cylindrical
Spherical
Articulated
Scara
Horizontally base-jointed Arm
Delta Geometry

22
Q

What type of robotic system is currently the most popular with industry?

A

Articulated

23
Q

Which type of robotic system is known for a cubic or rectangular work envelop?

A

Cartesian

24
Q

What does EOAT stand for and what is the functional definition of EOAT?

A

End-of-arm tooling

the devices, tools, equipment, grippers, and other tooling at the end of a manipulator that the robot uses to interact with and affect the world around it

25
Q

What are the 3 industrial robotic applications?

A
  • Material Handling Applications
  • Process Applications
  • Quality Assurance Applications
26
Q

Name the 5 types of grippers used in material handling applications.

A

Mechanical grippers
Magnetic Grippers
Vacuum Grippers
Balloon Grippers
Pin and Mandrel Grippers

27
Q

Name 4 types of welding processes used in process work applications

A

MIG Welding
Laser Welding
Spot-welding
Ultrasonic Welding

28
Q

If you have a limit switch in the field that has the actuator in the wrong position and a removeable head unit, how would you correct this situation?

A

By removing the appropriate screws in the head and then turning the actuator as needed before re-tightening the head screws.

29
Q

What do you need to know when selecting a limit switch?

A

How much amperage the contacts must withstand
How much force the object contacting the limit switch can generate
How fast the switch needs to respond

30
Q

What is an open loop system

A

Open-loop systems work on the assumption that the control pulse, whatever it may be, activates the motion system, and YOU ASSUME the robot performs as expected

31
Q

What is a closed loop system

A

Closed-loop systems send out the control pulse, whatever it may be, to initiate movement and then receive a signal back that confirms movement and in many cases in which direction and how far

32
Q

What is the ISO definition of an industrial robot?

A

An actuated mechanism programmable in two or more axes with a degree of autonomy, moving within its environment, to perform intended tasks.
