% Finish Time and Pen Time Table
[time_finish, time_table_pen] = cal_time_data(cp_ptp, ts1, time_wait);
max_pen_idx = length(time_table_pen) - 1;

% Position Reference
cp_ptp = cell2mat(cp_ptp);

y_ref = cp_ptp(2, :);

% Angle Reference
[theta1_ref, theta2_ref] = xy2theta(x_ref, y_ref, l1, l2);

% Theta and Omega Limitation Check
