We present kinematic structure of measurement arm along with its construction restrainsoriginating from using only accelerometers for determining relative positions of links. Method of calculating position of arm's end in relation to its base basing on orientation of individual links is presented. Accuracy and repeatability tests were performed using custom made test stand. The description of test stand, measurements procedures for last link changing its position in Cartesian directions and orientation in vertical axis is also included in the paper. These changes were justified in context of links orientation in relations to global coordinate system. Obtained tests results are presented and analyzed.
