Name 5 types of robot safety devices.

1. Emergency stops. 2. Barricades 3. Light curtains 4. Safety mats. 5. Signs and tape.

List 8 rules of robot safety

1. Remove all obstruction from work area. 2. Check for signs of damage to the robot. 3. Remove loose fitting clothing 4. Tie up long hair 5. Remove teach pendant from work area. 6. Locate emergency-stop button. 7. Ensure safety glasses are worn. 8. Ensure all people are outside the robot work area.

This includes gears, chains, and bearings as well as the physical structure itself.

Mechanical structure.

This is the most common type of gripper used in industry due to being inexpensive.

2 point curvilinear

There are 2 common types of grippers

2 point curvilinear 2 point parallel

This type of of gripper move in a straight line toward each other with finger tips always remaining parallel with each other.

2 point parallel

Most robots have between ____and _____axes.

3 and 6

Automated, reprogrammable, able to multitask

3 features are needed to define a machine as a robot.

Robots are used in many different tasks.

Assembly, material handling, welding, machine loading, painting and gluing.

Homing is an _______ procedure that causes the robots axes to move to a position where it actuates it home sensors.

Automatic

The joints are called

Axes.

The__________class of robot axes includes the waist, shoulder, and elbow.

Body class

Robots can improve quality of life by performing tasks that are

Boring

Name the nautical terms.

Yaw Pitch Roll

A_______is a specialized machine that coordinates a robots movements.

Controller

The____________resets its memory for each encoder to zero when the robot is at its home position.

Controller

Teach pendants are typically comprised of a

Display screen E stop Keypad

Teach pendants are typically comprised of the following components.

Display screen E stop Keypad

Electronic circuit cards in the controller that supply power to the robots motor.

Drives

The electronic device attached to the shaft of the servo motor

Encoder

This allows the robot controller to continually monitor the position of the servo motors.

Encoder

The wrist axes allow the robot too ok orient its

End effector

Used for a specific type of task, such as drilling, welding or cutting.

End of Arm

What does EOA stand for?

End of Arm

____________tooling enables a robot to perform work such as drilling

End of Arm

The mechanical structure of the robot includes.

Gears, chains, bearings, as well as the robot arm.

The most common type of end effector is a

Gripper

2 basic types of an End effectors are

Gripper End or Arm

These are used to grasp an object

Grippers

One type of end effector is the

Hand or gripper

Keys on teach pendant keypad that are assigned one specific function are referred to as

Hard keys

Many keys on the keypad are assigned one specific function. These are called

Hard keys.

This is used to reset the encoders value stored in the robot controller whenever the robot is homed.

Home position sensor.

This is an automatic procedure that causes the robots axes to move to a position where they actuate their home sensor.

Homing or nesting

Name the 3 advantages of a robot

Improve quality of life Improve product quality Reduce production cost.

Most robots look and act like an

Industrial machine

A______________ is an automatically controlled reprogrammable, multipurpose manipulator programmable in 3 or more axes.

Industrial robot

Before the robot is put into operation the arm should be.

Jogged

This is done to position the robot arm

Jogging

This means to move the robot arm manually under power.

Jogging

Name the most common functions found on a robot teach pendant.

Jogging Teach points. Move to a teach point Test input and outputs. Running a program

The arm of a robot is also called a

Manipulator

The part of the robot that actually moves and reaches. Also called an arm.

Manipulator

Name the 5 basic robot components.

Manipulator End effector Controller Drives Programming device.

The 2 point parallel gripper is____________

More expensive than the 2 point curvilinear gripper.

The purpose of the body Axes is to

Move the end effector to some point in space.

These axes are named using _________terms.

Nautical

All___________should be removed from the work area

Obstructions.

The wrist class of robot axes includes

Pitch, roll and yaw.

The 2 point curvilinear gripper is often

Pneumatic powered

Used to load programs for the robot to execute and also to control other robot functions.

Programming device

The home position _____________are used to reset the encoders

Sensors

The homing procedure for a servo robot homes the each axis is a ______ that ensures the robot will not crash into anything.

Sequence

A________motor drives each axis of the robot

Servo

An electrical motor that is connected by its shaft to the robots mechanical structure.

Servo motor

4 components of a robot axis

Servo motor Encoder Mechanical structure Home position sensor

The robot should always be jogged to a certain position.

Shutdown

A 2 point curvilinear gripper has 2 fingers jointed from a___________

Single pivot point

These keys have multiple-purpose functions.

Soft keys.

There are 3 reasons to jog the robot

Startup Teaching Shutdown

3 reason to jog a robot are

Startup, teaching and shutdown

Robot axes movement can either be

Straight lined or rotational

This is a handheld control device that is connected to the robot by an electrical cable.

Teach pendant

This is a necessary step in the programming of a robot.

Teaching

The part of the robot used to grasps tools.

The end effector

The fingers on a curvilinear gripper are only parallel with the part in one position.

True

The robot should always be homed when 1st turned on before it is operated or programmed.

True

These axes are named for human counter parts the resemble.

Waist Elbow Shoulder

The robots work area and equipment within it are called.
