The paper presents the design of a manipulator for servicing the elements of water and sewage infrastructure, in particular for installation and dismantling of pressure transducers without the need for earthmoving. In their construction a method of estimating the value of residual stresses in the cold shaped material of flat springs made of 1.1274 steel, based on measurements of Instrumental hardness was applied.
