Le dispositif de commande principale destiné à commander un robot comprend : un cardan commandé par un utilisateur ; et une partie liaison combinée en rotation à un robot et est actionnée pour permettre au cardan de se déplacer dans une position arbitraire dans l'espace. La partie liaison comprend : une partie liaison SCARA actionnée lorsque le cardan se déplace sur un plan horizontal ; et une partie liaison parallèle actionnée lorsque le cardan se déplace verticalement. Une liaison SCARA est responsable de la commande horizontale du cardan et une liaison parallèle est responsable de la commande verticale du cardan, ce qui fait tourner la partie liaison par le propre poids du cardan, et ainsi, la chute vers le bas du cardan est empêchée et le cardan peut toujours être maintenu dans une position horizontale.
