EN In this paper construction of CIE Exoskeleton is presented. CIE Exoskeleton is equipped with four actuated joints in hips and knees, which is minimal set of actuators to enable paraplegic operators to walk in exoskeleton with use of crutches. Moreover, we proposed a novel statically stable gait pattern which can be used by paraplegic subjects to restore locomotion even the exoskeleton ankle joint is not actuated. Proposed gait trajectory enables to shift center of pressure form a rear leg to a forward leg without leaving a stable pose. Furthermore the preliminary results of tests on planar gait trajectory planing accuracy were presented. Preliminary tests on accuracy of planar gait trajectory planing indicate that a step length cannot be estimated only from planar model due to pelvis or exoskeleton rotation during walking. It was shown that this effect can be partially compensated by using a linear correction function.
