While audiences can be unforgiving about flaws in the nonverbal behavior of humanoid robots,
the realistic touch to our performances has prevented any such encounters.
A phenomenon described by Masahiro Mori "Uncanny Valley" stands for a general, empirically measurable, paradoxical effect on the response to artificial figures presented to an audience.
We have reached quite the opposite effect with our artificial figures in the last 15 years.
The moment our puppets, for example, defy gravity,
we find that even this unnatural act is met by obvious consent.
(Also Jesco von Puttkamer (NASA) was impressed on the 24.9.2000
by this moment of our presentation on the
"Berliner United Space Parade" very much.)
Perhaps this is due to the fact that the puppet-maker Sölk H. Schulze
has always added certain elements of abstraction
to our puppets which in cooperation with our realistic way
of performing continues to fascinate our audiences.
