چکیده

Legged robots and animals can exhibit a variety of locomotory skills, trotting and walking being the most widely used modes of locomotion. Such behaviours are often defined with the overall stability of the system in mind and are inherently of periodic nature. Legged robots, possibly equipped with arms as well, in everyday scenarios, e.g. service or forestry/agriculture, will require also skills that are not of periodic nature but rather better described as single-shot manoeuvres.

Energy Dissipation Rate Control Via a Semi-Analytical Pattern Generation Approach for Planar Three-Legged Galloping Robot based on the Property of Passive Dynamic Walking

In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...

Projection based whole body motion planning for legged robots

In this paper we present a new approach for dynamic motion planning for legged robots. We formulate a trajectory optimization problem based on a compact form of the robot dynamics. Such a form is obtained by projecting the rigid body dynamics onto the null space of the Constraint Jacobian. As consequence of the projection, contact forces are removed from the model but their effects are still ta...

Motion planning for quadrupedal locomotion: coupled planning, terrain mapping and whole-body control

Legged robots promise an advantage over traditional wheeled systems, however, most legged robots are still confined to structured and flat environments. One of the main reasons for this is the difficulty in planning complex whole-body motions while taking into account the terrain conditions. This problem is very high-dimensional as it considers the robot’s dynamics together with the terrain mod...

Optimal Trajectory Planning of a Box Transporter Mobile Robot

This paper aims to discuss the requirements of safe and smooth trajectory planning of transporter mobile robots to perform non-prehensile object manipulation task. In non-prehensile approach, the robot and the object must keep their grasp-less contact during manipulation task. To this end, dynamic grasp concept is employed for a box manipulation task and corresponding conditions are obtained an...

From Robots to Humans: towards Efficient Forward Dynamics Simulation and Optimization Exploiting Structure and Sensitivity Information

The locomotion of quadruped and humanoid robots shares some characteristics with the one of animals and humans: a kinematic tree structure and a free-floating base, switches in the model due to different contact situations and a high number of degrees of freedom consisting of many links and many actuated joints. One main difference is in actuation: while robots commonly are driven by (at most) ...
