Imagine that you work in a company that builds robots. You are

asked to design a robot with hydraulic arms that can help out in
the home.
a) List some of the activities that this robot could use its
hydraulic arms for.
b) Why would hydraulic arms be better for these activities than
mechanical arms without hydraulics?

a) Some activities that a robot with hydraulic arms could perform in the home include:

1. Heavy lifting: The robot could help with moving heavy furniture, appliances, or objects around the house.
2. Assisting with chores: It could help with tasks like loading and unloading the dishwasher, doing laundry, or even helping with gardening.
3. Home repairs: The robot could assist in tasks like fixing plumbing, repairing electronics, or painting.
4. Personal care: It could assist with tasks such as helping a person get out of bed, helping with grooming, or even providing physical support for people with mobility issues.

b) Hydraulic arms would be better suited for these activities than mechanical arms without hydraulics for several reasons:
1. Higher strength and torque: Hydraulic systems can provide much more power compared to purely mechanical systems. This allows the robot to perform heavy-duty tasks and lift objects that may be beyond the capabilities of mechanical arms.
2. Smooth and precise movements: Hydraulics allow for fine control over the motion of the robot's arms. This precision is particularly useful when performing tasks that require delicate movements or positioning.
3. Adjustable force and speed: Hydraulic systems can be easily adjusted to vary the force exerted by the arms or the speed at which they move. This flexibility allows the robot to adapt to different tasks and handle different objects with varying levels of delicacy or strength.
4. Reducing strain: Hydraulic systems can absorb shocks and vibrations, reducing the strain on the robot's structure and increasing its longevity. This is especially important when handling heavy or irregularly shaped objects, which may cause excessive stress on mechanical arms.
5. Compact design: Hydraulic systems can be designed to fit in relatively small spaces, allowing the robot to have a compact form factor while still delivering significant power. This is beneficial, especially in a home environment where space constraints may be present.

By leveraging the capabilities of hydraulic arms, the robot can perform a wide range of tasks efficiently, safely, and with a high degree of precision.
