This paper presents a flexible 3D simulator able to reproduce the appearance and the dynamics of generic legged robots and objects in the environment at full frame rate (30 frames per second). Such a simulator extends and improves USARSim (Urban Search and Rescue Simulator), a robot simulator in turn based on the game platform Unreal Engine. This latter provides facilities for good quality rend...

Walking animals produce adaptive interlimb coordination during locomotion in accordance with their situation. Interlimb coordination is generated through the dynamic interactions of the neural system, the musculoskeletal system, and the environment, although the underlying mechanisms remain unclear. Recently, investigations of the adaptation mechanisms of living beings have attracted attention,...

Every day new technology appears. In the field of legged robots, it is not otherwise. LIDAR vision, artificial intelligence, computing power and drives help to improve state robots. One unsolved problems still terrain navigation, such as locomotion in resistive terrain. To determine correct locomotion, research must be carried out. this paper, we compare two different situations, where a six-le...

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...

The design of legged robots has long drawn on nature for inspiration. However, few of these robots exhibit the speed and robustness seen in even the simplest of animals. This paper presents the design and fabrication of a novel class of six-legged running robots based on biologically-inspired functional principles. We first describe recent findings in biological research that motivate our robot...

During locomotion, legged robots interact with the ground by sequentially establishing and breaking contact. The interaction wrenches that arise from contact are used to steer robot’s Center of Mass (CoM) reject perturbations make system deviate desired trajectory often them fall. feasibility a given control target (desired CoM wrench or acceleration) is conditioned point distribution, f...

We present a general trajectory generation scheme for a class of “kinematic” legged robots. The method does not depend upon the number of legs, nor is it based on foot placement concepts. Instead, our method is based on an extension of a nonlinear trajectory generation algorithm for smooth systems to the legged case, where the relevant mechanics are not smooth. Our extension is based on the rea...
