This paper discusses the design of a new snake-like robot without wheels, named ACM-R7. It has 18 DOFs, is 1.6 m in length and weighs 11.7 kg. It features a water-tight structure, a large motion range pitch joint of ±90 degree and a high output-power actuator arrangement, based on the coupled drive concept. Furthermore the control method “Loop Gait” is discussed. For this gait the ACM-R7 forms a loop...
This paper introduces a novel mobile robot design concept aimed at exploration of subterranean spaces. The key innovation is the combination of highly maneuverable-body elements with wheel/leg elements (ldquowhegsrdquo). This combination offers performance not possible with conventional ldquomonolithicrdquo wheeled or tracked mobile robots, or with current robot snakes. The paper covers two design...
A real-time obstacle avoidance algorithm based on sensor data is required for mobile robots. When a mobile robot is nonholonomic and it has polygonal body, the method using configuration space is usually applied. But, it is complex and it needs much computing power. On the other hand, artificial potential field is often used for real-time obstacle avoidance, however, most of them consider a mobile...
Urban search and rescue (USAR) involves locating, rescuing (extricating), and medically stabilizing victims trapped in confined spaces. In this paper we state the current approach to USAR, address the limitations and discuss the way for moving in rugged topography. To achieve objectives such as surveillance, reconnaissance, and rescue, it is necessary to develop a driving mechanism that can handle...
