_D_e_s_c_r_i_p_t_i_o_n:

     This data set is from a simulation of a servo system involving a
     servo amplifier, a motor, a lead screw/nut, and a sliding carriage
     of some sort. It may have been on of the translational axes of a
     robot on the 9th floor of the AI lab. In any case, the output
     value is almost certainly a rise time, or the time required for
     the system to respond to a step change in a position set point.
     The variables that describe the data set and their values are the
     following:

       [,1]  Motor  A,B,C,D,E
       [,2]  Screw  A,B,C,D,E
       [,3]  Pgain  3,4,5,6
       [,4]  Vgain  1,2,3,4,5
       [,5]  Class  0.13 to 7.10

_F_o_r_m_a_t:

     A data frame with 167 observations on 5 variables, 4 nominal and 1
     as the target class.
