statically stable gait
Opis:: Insect-like robots have many advantages concerning mobility and stability. The specific sequence of legs going through different phases, the gait, is important when planning and executing a complex motion. The notion of gaits was originally introduced by biologists but gaits also influenced robot development. Typical multipod robots are able to execute much more gaits than occur in wildlife. In this paper we present a formalism to express certain rules for reasonable gaits. We show an algorithm that enumerates all statically stable gaits according to our formalism. We then provide a gait classification by the example of six-legged robots. Finally, we introduce properties to evaluate gaits.

Opis:: The method of two-legged diagonal gait synthesis for the quadruped robot is introduced. The problem of dynamic postural equilibration taking into account the role of compliant feet is solved. The equilibrium conditions are split to the feet attachments points and the points within the feet-end area. In simulation example the slip avoidance condition is tested. Presented method has the meaning for motion synthesis taking into account the robot parameters and - for the design of the feet considering the dynamically stable gaits. The method was proved by using simulations and experiments.

Tematy:: Denavit-Hartenberg parameters

zero moment point (ZMP)
Levenberg-Marquardt algorithm
Cycloidal gait trajectory
Opis:: Legged machines have not been offered biologically realistic movement patterns and behaviours due to the limitations in kinematic, dynamics and control technique. When the degrees of freedom (DOF) increases, the robot becomes complex and it affects the postural stability. A loss of postural stability of biped may have potentially serious consequences and this demands thorough analysis for the better prediction and elimination of the possibility of fall. This work presents the modelling and simulation of twelve degrees of freedom (DOF) biped robot, walking along a pre-defined trajectory after considering the stability in sagittal and frontal planes based upon zero moment point (ZMP) criterion. Kinematic modelling and dynamic modelling of the robot are done using Denavit-Hartenberg (DH) parameters and Newton-Euler algorithm respectively. This paper also proposes Levenberg- Marquardt method for finding inverse kinematic solutions and determines the size of the foot based on ZMP for the stable motion of biped. Biped robot locomotion is simulated, kinematic and dynamic parameters are plotted using MATLAB. Cycloidal gait trajectory is experimentally validated for a particular step length of the biped.

Tytuł:: Legs Tip-Ground Contact Detection Based on Drive Currents in a Real Walking Robot
Autorzy:: Wąsik, M.
Powiązania:: https://bibliotekanauki.pl/articles/384891.pdf

Wydawca:: Sieć Badawcza Łukasiewicz - Przemysłowy Instytut Automatyki i Pomiarów
Tematy:: 5-legged walking robot

Opis:: To ensure an effective walking over uneven terrain for multilegged walking robots, there is necessary to detect the contact between the leg’s tips and the ground. It is essential to determine the moment when we should end the swing phase of the leg. This paper presents a method of detecting contact with the ground based on total current drawn by the servomotors of each robot’s legs. The method was developed using a 4-legs supported gait on 5-legged walking robot – PentOpiliones. This detection method has been tested and positively verified on a real robot. Also there has been tested the limitation of above method using a gait with different robot postures and different speeds.
