... in 'normal Scara' the positioning error accumulates over length -- with the parallel scara design this error is much more reduced and pretty uniform over the complete traveling range ...

single and paralel scara have different kinematics and configuration
both have advantages and disadvantages
you can see the configuration difference in this link [www.wangsamas.com]
