    Greetings,

    Possibly more of a mechanical question than an electronic one but there are still alot of design points and stuff.

    I got a whole bunch of stepper motors a while back and was thinking of reviving an old project (animatronic tail) by using them instead of servos. The main considerations are speed and torque. The servos were not up to the job and these stepper motors have about half the torque, but am I right in thinking they would be alot faster (never actually used steppers before) and can be geared down for more torque? Basic specs are as follows:

    Steppers:
    Step Angle (degrees) :1.8
    2 Phase
    Rated Voltage : 12V
    Rated Current : 0.33A
    Holding Torque : 2.3kg*cm

    Previously used servos:
    Speed (sec/60o): 0.16
    Torque (Kg-cm/Oz-in): 4.1/57
    Size (mm): 41 x 20 x 37
    Weight (g/oz): 45.5/1.6

    As for positioning, should be a simple matter of using an LED + detector, strobe disk and a counter?
