%% Example
% An example script, it is used to show how to use the arcs
% functions of the KUKA iiwa matlab toolbox
% First start the server on the KUKA iiwa controller
% Then run the following script in Matlab

% Note you have 60 seconds to connect to server after starting the
% application (MatlabToolboxServer) from the smart pad on the robot controller.
