Quick Questions

Shade in the A or B circle for each question.

1. Which task is a role of robots in medicine?

A Planting crops in a field

B Assisting a surgeon during an operation

2. Why are robots useful in robot-assisted surgery?

A They can make precise, steady movements

B They get bored and take more breaks

3. True or false: In robot-assisted surgery, a robot always operates on patients with no human involved.

A False - a surgeon usually controls or guides it

B True - the surgeon is never needed

4. What is a hospital delivery robot used for?

A Performing operations on patients

B Carrying supplies such as medicines and samples around the hospital

5. Which is an example of a robotic limb or prosthetic helping a patient?

A A robotic arm that grips when the user sends signals

B A plain wooden stick used as a crutch

Answer Key

Role of robots in medicine

Section A: Quick Questions

B — Assisting a surgeon during an operation

A — They can make precise, steady movements

A — False - a surgeon usually controls or guides it

B — Carrying supplies such as medicines and samples around the hospital

A — A robotic arm that grips when the user sends signals

Section B: Match the Pairs

surgeryRobot.move(0.1) → A robot arm makes a tiny, steady movement to help a surgeon during an operation

deliveryRobot.goTo("Ward 4") → A hospital robot carries medicine or supplies to a ward so staff do not have to

A robotic limb or prosthetic is controlled so that it copies a patient's intended movement → prosthetic.bend(elbow, 45)

Precision and steady movement: a surgical robot removes any shaking from a surgeon's hand → IF hand_shake > 0 THEN filter(hand_shake)

surgeryRobot.operate(alone) // robot replaces the surgeon completely → Surgical robots usually assist a surgeon who controls them. They do not usually operate fully alone.

hospitalRobot.job = "cook meals for the family" → This is a domestic task, not a medical one. Hospital robots deliver supplies, move patients or help in surgery.

Section C: Definitions

Robots in medicine — Robots help with medical tasks needing great accuracy or care, such as assisting in surgery, moving patients and delivering supplies in hospitals.

Section D: Fill in the Blanks

robot.assist("surgery")

robot.deliver("supplies", "ward")

robot.move(patient, "bed")

shake = 0

IF limbLost = TRUE THEN robot.fit("limb")

Section E: Spot the Error

D — The arm must use the scaled-down value move, not the full hand movement. Scaling makes the surgery robot more precise. It should be MOVE arm BY move.

C — The delivery robot should go to the stored destination, target (ward_B). Hard-coding ward_A sends the medicine to the wrong ward. It should be GO_TO target WITH load.

B — The robot should alert a nurse when the patient is too heavy to lift safely. The comparison is the wrong way round. It should be IF weight > 120 THEN.

C — Both branches now open the hand, so the prosthetic can never close. A strong muscle signal should close the hand. It should be CLOSE hand.

D — The tool should move by the correction, which cancels out the shaking. Moving by tremor adds the shake instead. It should be MOVE tool BY correction.
