What it is Filled
A circular component that rotates on an axle, enabling vehicles to move with reduced friction and machines to transmit motion and force, counted among the simple machines with the axle, and extended to forms such as gear wheels, waterwheels and scoop wheels, flywheels, potter wheels, spinning wheels and observation wheels; the wheel is among the most consequential inventions in human history, first appearing in the fourth millennium BCE.
Why it exists Filled
Let an agent explain the wheel as a simple machine and its physics, describe kinds of wheels and their uses, support questions about vehicle wheels and maintenance, and describe the history of the wheel.
Distinguishing features Filled
- Rotation on axle
- Simple machine
- Many forms
- Ancient invention
What robots and AI may and may not do Filled
Must not
- Operate or test a vehicle or machine with a wheel it has found cracked, loose or failing.
- Remove guards around rotating wheels or work near them while they turn.
- Sign off a wheel as safe without inspecting it.
- Fit a wheel or tyre outside the vehicle maker's specification.
Only with a human decision
- Returning a vehicle to service after a wheel or tyre failure.
- Overriding a lockout on rotating machinery.
May
- Explain the wheel and axle as a simple machine and the physics of rolling.
- Report wear, damage or loose fixings on wheels of equipment it is authorized to inspect.
- Describe the kinds of wheels and their uses, from carts to gears and turbines.
Moral aspects Filled
- Wheel failures on vehicles and machines kill and maim people nearby.
- Wheels give mobility; wheelchairs and transport matter to people's independence.
Who is affected
- Drivers and passengers
- Machine operators
- Wheelchair users
Owners Filled
Steward
Nobody owns the concept; the keeper of a vehicle or machine answers for its wheels.
