A robotic machine can be set up to do exacting, repetitive work that would take longer and be more difficult for a human.
An "ideal machine" would produce the same amount of work as its energy input.
The work done by a machine is called work output
Machine work
No, there is not such thing as an ideal machine; it's just an idea.
In practical there is no machine which have efficiency 100%,i.e. output work = input work. But an ideal machine have efficiency of 100%, for an example a Carnot's heat engine. The efficiency of this engine is 100% but it is an ideal situation. As an expression of efficiency it is equal to W/Q, where W is work done by the system and Q is heat put into the system. For efficiency =1 ,i.e.100% if and only if W=Q and vice verse.
Such as machine is said to have an efficiency of 100%. Since some type of energy loss is unavoidable, this is not possible in real life, but in some cases it can be approximated quite well.
Work: The work done by the force is the same as the work done on the load in an ideal simple machine.
The work done by a machine is called work output
Machine work
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
Power
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!

Machine without any friction is an ideal machine so an ideal machine cannot have friction.
Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.
