The complexity of how such a tax may be calculated fairly in the first place is incomprehensible. Never minding the fact that the definition of ‘robot’ is unclear.
Also, productivity growth is in decline  so slowing the progress through taxation could have even greater negative economic impact, rather than the reverse perhaps implied by the question.
Governments have to function, true, but a simpler manner of taxation is needed than the blunt instrument of ‘robots’ and this gets even more complex if you add AI into your question
