%MDL_MICO Create model of Kinova Mico manipulator
|
|
%
|
|
% MDL_MICO is a script that creates the workspace variable mico which
|
|
% describes the kinematic characteristics of a Kinova Mico manipulator
|
|
% using standard DH conventions.
|
|
%
|
|
% Also define the workspace vectors:
|
|
% qz zero joint angle configuration
|
|
% qr vertical 'READY' configuration
|
|
%
|
|
% Reference::
|
|
% - "DH Parameters of Mico" Version 1.0.1, August 05, 2013.
|
|
% Kinova
|
|
%
|
|
% Notes::
|
|
% - SI units of metres are used.
|
|
% - Unlike most other mdl_xxx scripts this one is actually a function that
|
|
% behaves like a script and writes to the global workspace.
|
|
%
|
|
% See also SerialLink, Revolute, mdl_jaco, mdl_puma560, mdl_twolink.
