The purpose of this paper is to elaborate not on the bionic pattern of walking robot. Our own simple idea of 4 degree of freedom (DOF) walking robot with the ability to walk on flat surfaces, rotate and climbing upstairs was made using vertical moved legs with rotary foot and additional controlled mass. In this paper, based on former idea, prototype model for only flat surface walking task 3 DOF were presented. Parts of the robot are moving thanks to servo motors. The paper contains kinematics and centre of gravity analysis, presentation of robot and its control system made using Pololu controller. Conducted experiments confirmed presented idea.

Many of design of walking robots are based on bionics ideas. Some of its are very similar to original biology conception, but there are very complicated. The idea of paper was to elaborate no bionic pattern, own simple idea of walking robot for task walking on flat surface, rotate, and climbing on stairs. In paper was presented the idea of solution walking robot with this ability. In presented design was used 4 DOF. Was presented idea of this solution, kinematics analyse and simulation software.

The paper presents the construction of a multi-purpose mobile robot. The main assumption was to create a robot which would be able to move in all directions, grab items and communicate with the environment. This developed robot controls the system based on Think-pad X41 tablet with a special interface and its own software.

This paper presents parallel kinematic manipulator design. A manipulator with three axis and parallelogram mechanism was made using aluminium profile rods. This mechanism was controlled by PC with the use of stepper motors. Kinematics analysis was conducted and its findings were used to make a special software to generate G-code control file. X and y mouse cursor indications with given z value were used as data showing the position of the effector to establish the movement of the arms of the presented manipulator. Step2CNC software was used to control the manipulator. Tests have confirmed the correctness of the study.

The paper presents a model of tool with controlled geometry of the active surface. This tool is very suitable for use with an industrial robot, for example, to form polystyrene foam. The tool was built in the form of two discs mounted on axes stepper motors positioned in the frame. This discs combined using two wires with feature a length of a wire compensation system. It was made using the spiral spring. Tool geometry was set by rotating one of the discs at a specific angle (0-180o). After starting the both engines, concurrently at the same direction, surface of tool action is obtained in the form of hyperboloid. To run the tool uses stepper motors connected to a computer equipped with an interface card and specially developed control software. Tool joined to the IRb60 robot wrist can obtain curved surface as a superposition of the kinematics of tool and robot wrist.
