NO A PUMA ROBOT..AND A SMALL xyz table..


 I have a project like that in mind

The TMS320LF2407 (or TMS320LF2406)DSP from Texas Instruments has been
chosen to perform the motor control and low-level processing duties.  This
DSP features high-speed processing, a built-in communication protocol, two
ADC converters, and quadrature capture pins for positional feedback from
the motors. 
 
and only one is needed for three motors... also free samples from Texas
Instruments.

you would need two pics per motor to do it properly..?????????
