% name name of robot, used for graphical display
% manuf annotation, manufacturer's name
% comment annotation, general comment
% plotopt options for plot() method (cell array)
% fast use MEX version of RNE. Can only be set true if the mex
% file exists. Default is true.
%
% Properties (read only)::
%
% n number of joints
% config joint configuration string, eg. 'RRRRRR'
% mdh kinematic convention boolean (0=DH, 1=MDH)
