Write a solution for the following questions: (a) What is the term for a code structure that executes a block of code multiple times? (b) Calculate the total expenses: 12 GHC200 + GHC150 + 7 GHC23. (c

The code structure shown, which executes a block of code multiple times, is known as a loop.

• Loop

To calculate the total expenses, we follow the order of operations (multiplication before addition).

To handle both heavy and delicate objects safely, the robotic arm needs improvements in its ability to sense and adapt its grip.

(i) Force/Pressure Sensors: Adding sensors to the gripper would allow the robotic arm to detect the amount of pressure being applied to an object, enabling it to adjust its grip strength to avoid crushing delicate items while still holding heavy ones securely.

(ii) Adaptive End-Effector/Gripper: The existing gripper could be replaced or improved with one that has adjustable gripping force, compliant (soft) materials, or multiple fingers that can conform to different object shapes and apply varying pressure.
