Experimental measurements focused on the investigation of a fibre behaviour are performed on an assembled weigh-fibre-pulley-drive mechanical system. The fibre is driven with one drive and it is led over a pulley. On its other end there is a prism-sh

Fibres, cables and wires can play an important role in design of many machines. One of the most interesting applications is replacement of chosen rigid elements of a manipulator or a mechanism by fibres. The main advantage of this design is the achie

This paper introduces a new calibration and measuring machine RedCaM for 6 DOF with minimized transfer error. As a parallel structure it profits from the fact that sensors errors are not chaining. The redundancy of sensors provides better accuracy, s
