Quick Questions

Shade in the A or B circle for each question.

1. Why is a robotic arm on a car production line classed as a robot?

A It has a mechanical frame, electrical components and a program

B It is large and made of metal

2. Which part of a robotic arm gives it the ability to bend and reach different positions?

A Its program counter

B Its joints

3. What is the job of a gripper on a factory robotic arm?

A To pick up and hold items

B To store the program

4. What makes a robotic arm repeat the same task on every item on the production line?

A A program of instructions it follows each time

B The arm decides for itself what to do each time

5. Which of these are the electrical components of a robotic arm?

A Joints and gripper

B Motors and sensors

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1robotic arm		AA robot must be programmable. The program tells the motors and sensors what to do, and without one the arm cannot work as a robot.
2gripper		Barm.joints = 6
3The arm's joints and frame are its mechanical structure, so it can reach and move items		CThe part at the end of a robotic arm that holds or picks up an item on the production line
4The same program is repeated for each item that arrives on the production line		DFOR item ← 1 TO 100 pick_and_place() NEXT item
5A robotic arm has no program, because its motors make it work by themselves		EA robot does not have to move around. A fixed arm is still a robot because it has structure, electrical components and a program.
6A factory robotic arm is not a robot because it is fixed in one position and does not move around		FA factory robot with a jointed frame and gripper, electric motors and sensors, and a program that repeats a task on each item on a production line

Answer Key

Example robot: factory equipment

Section A: Quick Questions

A — It has a mechanical frame, electrical components and a program

B — Its joints

A — To pick up and hold items

A — A program of instructions it follows each time

B — Motors and sensors

Section B: Match the Pairs

robotic arm → A factory robot with a jointed frame and gripper, electric motors and sensors, and a program that repeats a task on each item on a production line

gripper → The part at the end of a robotic arm that holds or picks up an item on the production line

The arm's joints and frame are its mechanical structure, so it can reach and move items → arm.joints = 6

The same program is repeated for each item that arrives on the production line → FOR item ← 1 TO 100 pick_and_place() NEXT item

A robotic arm has no program, because its motors make it work by themselves → A robot must be programmable. The program tells the motors and sensors what to do, and without one the arm cannot work as a robot.

A factory robotic arm is not a robot because it is fixed in one position and does not move around → A robot does not have to move around. A fixed arm is still a robot because it has structure, electrical components and a program.

Section C: Definitions

robotic arm — A factory robot with a jointed frame and gripper, electric motors and sensors, and a program that repeats a task on each item on a production line.

Section D: Fill in the Blanks

FOR item = 1 TO 10
   arm.pickUp()
NEXT item

arm.rotate(joint1, 45)

IF sensor.detects(item) THEN
   arm.grip()
ENDIF

arm.baseFixed = TRUE
agv.baseFixed = FALSE

PROCEDURE PickAndPlace()
   arm.grip()
ENDPROCEDURE

Section E: Spot the Error

D — After the gripper closes on the item, the arm must carry it to the box. Moving back to the conveyor means the item is never placed. It should be MOVE arm TO box.

D — The MOVE command needs the word TO between the arm and its destination. It should be MOVE arm TO box.

B — An IF statement needs THEN at the end of its condition, so the program knows what to do when the sensor reading is true. It should be IF angle < 90 THEN.

A — The arm should repeat its task for each item while the belt is running. Testing for FALSE means the loop would not run while the belt is moving. It should be belt_running = TRUE.

B — A robotic arm bolted in one place has a FIXED position, so it reaches with its arm. Testing for MOVING would make this fixed robot drive with wheels. It should be IF position = FIXED THEN.
