The animatronic model is actuated by servo motors. Filaments that represent biological muscles are connected to the motors individually or in symmetrical pairs. A total of 16 motors are available, 14 of those are allocated to the muscles listed below. The other two motors are spare motors that can be used in future expansions of the model.
Muscles simulated in AnTon:
Genioglossus (three separate sections)
Hyoglossus (two separate sections in left/right pairs)
Styloglossus (left/right pair)
Pterygoid medial (left/right)
Pterygoid lateral (left/right)
Of these, the velum was not used in the experiments, as nasalised vowels are not prominent in English.
The muscles implemented in AnTon, as published in Hofe & More, Connection Science 20(4): 319-36, 2008. See section 'Publications' for references.
The servo base board. It provides slots for 16 standard servo motors.
The servo motors are controlled by a controller board connected to a standard PC USB port. The number of motors could easily be upgraded to 32 by adding a second board.
Servo motors: 16x Cirrus CS601BB
Controller board: ServoCenter v3.1 USB
Control software: Written as PD (pure data) extensions in C.
