Experimental construction of walking robot
(Wydawnictwa AGH, 2008) Babiarz, Artur; Jaskot, Krzysztof
The paper presents an experimental construction of six legs walking robot. In the paper, we consider problem of control six legs robot with eighteen servomotors. Each of the legs is equipped in three servomotors what mean 3DOF (degree of freedom) per leg. Using multiprocessor architecture, one microcontroller for servo control and one for analyse data from sensors are described. Mobile robot is a machine that can operate in a human-made environment. By control, in this case we will understand to be able to avoid collisions with obstacles during walk in unknown environment. Legs movement algorithm is described. Presented algorithm generates movement of legs with surface detection. All of presented algorithms were written in C language. Results of real application are also shown. Preliminary results of work on fully autonomous walking robot that can operate in human environment are presented.

Identification of the servo motor used in the walking robot
(Wydawnictwa AGH, 2010) Piątek, Marcin
The paper describes the servo motor modelling and identification procedures. The hexapod - six-legged walking robot is presented. The Hitec servo motors are the robot actuators. The development environment where all experiments are performed is described in detail. The precise analysis of the servo motor static behaviour is done and the results are shown in numerical and graphical forms. An effort to identify the servo motor as a linear object has been taken. Finally, a non-linear model structure is assumed. The identification results are presented.
