%MDL_PUMA560 Create model of Puma 560 manipulator
%
% MDL_PUMA560 is a script that creates the workspace variable p560 which
% describes the kinematic and dynamic characteristics of a Unimation Puma
% 560 manipulator using standard DH conventions. 
%
% Also define the workspace vectors:
%   qz         zero joint angle configuration
%   qr         vertical 'READY' configuration
%   qstretch   arm is stretched out in the X direction
%   qn         arm is at a nominal non-singular configuration
%
% Notes::
% - SI units are used.
% - The model includes armature inertia and gear ratios.
%
% Reference::
% - "A search for consensus among model parameters reported for the PUMA 560 robot",
%   P. Corke and B. Armstrong-Helouvry, 
%   Proc. IEEE Int. Conf. Robotics and Automation, (San Diego),

% MODEL: Unimation, Puma560, dynamics, 6DOF, standard_DH

%
% Notes:
%    - the value of m1 is given as 0 here.  Armstrong found no value for it
% and it does not appear in the equation for tau1 after the substituion
% is made to inertia about link frame rather than COG frame.
% updated:
% 2/8/95  changed D3 to 150.05mm which is closer to data from Lee, AKB86 and Tarn
%  fixed errors in COG for links 2 and 3
% 29/1/91 to agree with data from Armstrong etal.  Due to their use
%  of modified D&H params, some of the offsets Ai, Di are
%  offset, and for links 3-5 swap Y and Z axes.
% 14/2/91 to use Paul's value of link twist (alpha) to be consistant
%  with ARCL.  This is the -ve of Lee's values, which means the
%  zero angle position is a righty for Paul, and lefty for Lee.
%  Note that gravity load torque is the motor torque necessary
%  to keep the joint static, and is thus -ve of the gravity
%  caused torque.
%
% 8/95 fix bugs in COG data for Puma 560. This led to signficant errors in
%  inertia of joint 1.
