[Star Wars] Given the obvious advantages of a robot army, why were they made so inefficient?

A droid army should be able to communicate wirelessly, have perfect aim, act in perfect unison, flawlessly execute and react to any strategy, and be so heavily armored and mobile that conventional weapons are useless.

Instead the Separatists made an army of weak robots with terrible aim that are laughably foolish and borderline goofy. 

Why would you ever make an army of robot Jerry Lewises?

The hardware designs were intentionally economical because they had to be mass-produced (advanced units like Destroyers were in production, but very very slow and expensive to make). They were working out the software glitches, but Sidious forced them to act before they were ready. They expected their enemies to surrender at the sight of their arrayed troops, but that didn't happen.

After all, Sidious didn't need an army of robots. He needed an army of clones.
