The paper deals with a windshield wiper mechanism with two parallel rocker blades having a complex topological structure. In the first part of the paper, the mobility of the mechanism is analyzed by means of the simplest formula for planar linkages. Also, the topological structure consisting of adyad and a tetrad has been outlined. In the second part of the paper, a kinema-tic analysis of the multi-contour mechanism is performed, the angular displacements of the two rocker blades being obtained. In this regard the independent contour method has been used, the angular displacements of all kinematicelements of the mechanism being calculated. Moreover, the displacement systems have been derived in order to obtain the velocities and late-on the accelerations of the mechanism elements. Finally, the paper ends with the displaying of the kinematic charts of the mechanism elements of which those with themovement of the two parallel rocker blades are the most wanted. This is due to the requirement of maximization of the wiping surface which is a very important safety issue.

The paper presents several types of mobile robots (MR) with 4, 6 and 8 wheels adapted for moving on uneven terrain. In the case of MR on 4 wheels, their diameter is limited and the chassis is raised, the ground clearance being higher than the height of a bump. MRs on 4 or 6 wheels have the chassis linked to the motor wheels by articulated bars as a dyad or tetrad variable geometry suspension. MR on 8 wheels use 4 planetary motor gear sets in tristar shape.

The paper presents a structural analysis of the complex mechanisms type screw-jack. The mechanism mobilityanalysis using various generally applicable formulas has been performed. A newkinematic scheme of the jack linkage has been proposed. Besides the actuatorscrew, it has a planar kinematic chain with articulated bars. With regard tothis new mechanism, an algorithm for static calculus has been developed, inwhich the automobile gravity force is the main exterior force.
