In this paper, we describe a gait generation method for the crawling motion of a legged robot using Normalized Energy Stability Margin (NESM). The crawling motion is a method of locomotion that, since the robot is very close to a state of falling, its leg and torso are grounded alternately in order to enable the robot to move with a low center of gravity. It has the benefit of decreasing the impact...
High mobility, large obstacle performance, narrow space crossing-over capacity and stable data communication are important features for a rescue robot. The authors proposed a parent-child robot system that could achieve all of these abilities. The robot system is composed of a parent robot, a tracked child robot and a legged robot. The parent robot has high mobility and can climb over ordinary obstacles...
In rescue robot competition field, a robot needs to operate in various dynamic environments where they encounter a multitude of unknown both static and/or moving obstacles and targets. Hence, the robot should have high mobility performance to cope with this situation. Here, we propose a new robot hybrid mechanism that consists of wheeled and legged actuators. Based upon the designed mechanism, we...
